Page 76: B2.3 How To Enable Settings
B2.3 How to Enable Settings Parameters described in Section B2.2.7, “controller Parameters,” and Section B2.2.10, “I/O Parameters,” must be enabled before their settings can take effect. This section describes how to enable various settings and check for successful completion. Table B2.25 lists the input relays and Table B2.26 lists the I/O data registers that are used for enabling controller parameters and I/O parameters.
Page 77 CAUTION The OPE register functions only when the module is in Setup mode. Accessing the OPE register before transiting to Setup mode generates an error, and returns an error value of –32767 in the STUS register. CAUTION Always finishing enabling all required settings, always set SETUP to '0: Disable setup instruction operand'.
Page 78  State Transition The operating states of the module can be classified into 3 types. For details on how to transit to a new state and check for successful transition, as well as details on the content of registers and relays in each state, see Table B.2.28, “Content of Registers and Relays in Each Operating State”.
Page 79  Procedure for Enabling Controller and I/O Parameter Values Figure B2.3 illustrates the procedure for enabling controller parameter and I/O parameter values. Two I/O data registers, namely, SETUP and OPE, are used to enable settings, whilst three relays (SETUP.R, CMDRDY, MDLRDY) and one input data register (STUS) are used to check for successful execution.
Page 80 CAUTION The STUS register is a read-only register, which is updated after execution of each setup instruction. When executing a sequence of setup instructions, check the STUS register after each execution to determine if setup is successful. CAUTION If a sequence program has a long execution cycle, a rising edge in the CMDRDY relay may fail to be detected.

Page 117: Part-C Function Description
TOC C-1 Temperature Control and PID Module PART-C Function Description IM 34M06H62-02E 3rd Edition PART-C describes the functions of the module. This module has four controller loops, which can be configured to operate in pairs or individually to serve different purposes. This part first describes the controller mode that defines the way these controller loops are used, followed by the individual functions of the module.
Page 118 Blank Page...
Page 119: C1 Controller Mode
C1-1 C1. Controller Mode The controller mode defines the interdependency of the four controller loops of the module. When the controller mode is set to single loop, each controller operates independently. When the controller mode is set to cascade control or two-input changeover control, a pair of controller loops 1 and 2, or a pair of controller loops 3 and 4, cooperate to function like a single controller.
Page 120: C1.1 Single Loop
C1-2 C1.1 Single Loop When the controller mode is set to Single Loop, you get the most basic control operation where each controller operates independently. You will set up each loop separately, and perform run/stop and other operations for each loop separately. C4.

Page 124: Cascade Control Operation
C1-6 C1.2.1 Cascade Control Operation  Operating Status and Cascade Control In cascade control mode, run/stop selection (RUN/STP) or automatic/manual/cascade selection (A/M/C) is specified using parameters of the secondary loop (loop 2 or 4). With “Stop” specified, the secondary loop outputs the preset output (n.POUT) and the preset cooling output (n.POUT.C) (for heating/cooling control), and the control output (HOUT) from the primary loop is set to its preset output (n.POUT).
Page 125 C1-7  Performing PID Adjustment in Cascade Control Use the following procedure to perform auto-tuning or manual PID adjustment: (1) Perform auto-tuning or manual PID adjustment in automatic mode to determine optimal PID values for the secondary loop. (2) Switch to cascade control mode, and perform auto-tuning or manual PID adjustment for the primary loop to determine optimal PID values.
Page 126: C1.3 Two-Input Changeover Control
C1-8 C1.3 Two-input Changeover Control When the controller mode is set to Two-input Changeover Control, a pair of controller loops 1 and 2 or a pair of controller loops 3 and 4 is used to control a single target through changeover between the two PVs. This flowchart illustrates the module functions as functional blocks.

C1-11 C1.4 Disabled Mode The Disabled mode suspends one or both controller functions for a pair of two loops. The ‘Single Loop (odd-numbered loop disabled)’ controller mode disables the odd-numbered loop. The Both Loops Disabled mode disables both loops of the pair. All controller functions are deactivated for a disabled loop.

Page 135: Control Type Selection
C2-5 C2.1 Control Type Selection The Control Type Selection function selects the type of control and computation for a controller. You can use the Control Type Selection (OT) parameter to select one out of four types of control and computation function. For details on each type of control and computation function, see Sections C2.4.1, "ON/OFF Control Output"...

Page 137: Control Types And Their Operations
C2-7 C2.4 Control Types and their Operations Two control types are available: ON/OFF control output and PID control output. C2.4.1 ON/OFF Control Output In ON/OFF control, the module turns on or off an output according to the deviation between the control set point (CSP) and the PV. To set the control type to ON/OFF Control, set the Control Type Selection (OT) parameter to 1.
Page 138 C2-8 Figure C2.3 ON/OFF Control Operation Example (for reverse operation)  Manual Operation In Manual mode, you can control the ON/OFF output manually by writing 100.0 or 0.0% to the Manual Output (MOUT) parameter. If you set MOUT to a value smaller than 0.0%, the value is treated as 0.0%. If the preset value is 0.1% or larger, it is treated as 100.0%.
Page 139: C2.4.2 Pid Control Output
C2-9 C2.4.2 PID Control Output In PID control output, the module continuously adjusts its output according to the deviation between the control set point (CSP) and the PV. To select PID control output, set the Control Type Selection (OT) parameter to 0. For details, see Section C2.1, “Control Type Selection."...
Page 140 C2-10 Figure C2.4 Time-proportional PID Control Output  Continuous PID Control Output In continuous PID control, the PID computation result, HOUT, is output as a continuous analog signal in the form of a 4-20 mA current.

Page 141 C2-11  Output Limiter The output limiter defines the range for the output control value by specifying the upper and lower output limits, which may be defined for each loop or each PID parameter group. Table C2.11 Output Limiter Registers Data Position Number Default Symbol...
Page 142 C2-12  Rate-of-change Limit The rate-of-change limit prevents drastic changes in the output by defining the maximum rate of change allowed in the control output. This function is useful for protecting a controlled load or machine. For example, supposing that the rate-of-change is set to 2% per second, even if the PID computation result changes instantly from 0 to 100%, the actual output changes linearly from 0 to 100% over a duration of 50 s.
Page 143: C2.4.3 Heating/Cooling Pid Control
C2-13 C2.4.3 Heating/Cooling PID Control In Heating/Cooling PID Control, the module computes its output according to the deviation between the control set point (CSP) and the PV, and outputs the PID computation result as heating and cooling outputs. To select Heating/Cooling PID Control, set the Control Type Selection (OT) parameter to 2.

Figure C2.8 Positive Dead Band (for P control) When a negative dead band value is specified, both heating and cooling outputs are generated and overlap within the dead band.
Page 147 C2-17  Setting the Cooling Gain In heating/cooling PID control, control output is calculated based on heating parameters. Parameters other than proportional band, namely, integral time and derivative time, are common to both heating and cooling output calculations. The proportional band for cooling output is adjusted using the cooling gain as follows: - Proportional band for heating output = Proportional band - Proportional band for cooling output = Proportional band ÷...

Page 149 C2-19  Manual Operation In Manual mode, the output from the module is determined by the Manual Output (MOUT) parameter or the Manual Cooling Output (MOUTC) parameter, either of which can be set manually. The heating output range is between 0% and the Upper Output Limit (OH), and the cooling output range is between 0% and the Lower Output Limit (OL).
Page 150 C2-20  Heating/Cooling Control Output Limits The upper limit of the heating output is defined with the Upper Output Limit (n.OH) parameter (where n: 1-4), and the upper limit of the cooling output is defined with the Lower Output Limit (n.OL) parameter (where n: 1-4). The lower limit of the heating or cooling output is fixed at 0%.
Page 151: C2.4.4 Heating/Cooling On/Off Control
C2-21 C2.4.4 Heating/Cooling ON/OFF Control In Heating/Cooling ON/OFF Control, the module turns on or turns off the heating or cooling output depending on the deviation between the control set point (CSP) and the PV. To select Heating/Cooling ON/OFF Control, set the Control Type Selection (OT) parameter to 3.
Page 152 C2-22  Manual Operation In Manual mode, the output from the module is determined by the Manual Output (MOUT) parameter or the Manual Cooling Output (MOUTC) parameter, which you can set manually. You may set MOUT and MOUTC independently. The value of MOUT or MOUTC must be either 0.0% or 100.0%.
Page 153: C2.5 Analog Output
C2-23 C2.5 Analog Output The analog output function is available only with F3CU04-1S. If an output terminal is not used as a control output, it may be configured for an analog output (4-20 mA). To configure an output terminal for analog output, set its corresponding bit in the Output Type Selection (OUTPUT) parameter to 1 (Analog Output), and set the corresponding Output Terminal Selection (OUTSELn) parameter (n = 1-8) to an integer ranging from 21 to 28 corresponding to AOUT1-8.
Page 154: C2.6 External Output
C2-24 C2.6 External Output You may switch the output between Control Output (HOUT) and External Output (EXOUT) using the EXOUT/OUT parameter. When EXOUT/OUT is set to 0 (Normal output), the PID computation result or some other control and computation result is output. When EXOUT/OUT is set to 1 (External output), the output value specified by the External Output (EXOUT) parameter is output.

Page 161: C3.2 Power Frequency Selection
C3-7 C3.2 Power Frequency Selection Power frequency may be set either by switches or software. Power frequency selection by software is available only when switches SW1-4 = OFF and SW5=0. The default value is determined by SW1-2. An appropriate power frequency setting reduces the interference of common-mode noise from the power supply on input signals.
Page 162: C3.3 Input Range Setting
C3-8 C3.3 Input Range Setting For each instrument range selected using Input Type Selection, you may define an input range, which is the actual temperature range to be monitored, by specifying upper (RH) and lower (RL) limits within the instrument range. Some input types such as thermocouple W, however, allow an input range that is wider than the instrument range.
Page 163: C3.4 Pv Range Setting (For Use In Two-Input Changeover Mode Only)
C3-9 C3.4 PV Range Setting (for use in two-input changeover mode only) The PV range setting defines the range of the output process value in Two-input Changeover mode, in cases where the two input signals have different input ranges. The PV range setting can only be changed in the two-input changeover mode and no other mode.
Page 164: C3.5 Burnout Detection
C3-10 C3.5 Burnout Detection Burnout detection checks for an open circuit on an input. For thermocouple or RTD input, you may define a burnout condition by specifying the direction of change in the input value and the final input value. For DC voltage input, burnout detection is not available.
Page 165: C3.6 Reference Junction Compensation
C3-11 CAUTION Burnout detection is not performed when EXPV/PV is set to “1: external input”. CAUTION If the Burnout Selection (BSL) parameter is set to ‘Down-scale’ for a thermocouple range, a burnout may not be detected in high temperature environments exceeding 40C. In this situation, set the alarm type to ‘Lower Limit’, set an appropriate alarm preset value, and use the alarm for burnout detection instead.
Page 166: Broken-Line Biasing
C3-12 C3.7 Broken-line Biasing The broken-line biasing function adds different bias values to input values depending on their magnitude. This function is useful for correcting offset or gain error (due to sensor characteristics, degradation or other reasons) over parts of an input range. As shown in the figure below, by specifying the input values (X) and corresponding bias values (Y) for any three points, bias correction is performed throughout the input range.
Page 167: C3.8 Fixed Biasing
C3-13 C3.8 Fixed Biasing The fixed biasing function adds a constant bias to input values throughout the input range. This function is especially useful when a sensor output is always lower than true values by a fixed amount due to the physical condition of the sensor. For example, it may be used when the temperature of a material in a furnace is indirectly determined by measuring the ambient temperature in the furnace, where a fixed bias is added to the ambient temperature to represent the temperature of the material.
Page 168: C3.9 Square Root Extraction
C3-14 C3.9 Square Root Extraction The square root extraction function is especially useful for converting differential pressures measured with a restriction flowmeter using an orifice or nozzle into flow rates.

Page 169: C3.10 Input Filtering
C3-15 C3.10 Input Filtering The input filtering function removes noise from input signals. It is especially useful for removing high frequency noise from flow rate or pressure input signals. When a larger time-constant is specified for this function, more noise is removed and the input signal becomes cleaner and more stable.

Page 172: C3.12 External Input
C3-18 C3.12 External Input The input value used for monitoring and controlling may be switched to an external input, which may be, say, processed data from a CPU module. An external input must fall within the range of -5.0% to 105.0% of (SL to SH). Use the EXPV/PV parameter to switch between external input and normal input.

C4-1 C4. SP-Related Functions This chapter describes the selection of the set points used in control and computation functions, as well as changes in set point value accompanied by a change in operation control modes.

Page 174: C4.1 Set Point (Sp)
C4-2 C4.1 Set Point (SP) Any one of the pre-defined set points (1.SP to 4.SP) or a remote set point (RSP) can be selected as the control set point (CSP). The set points (1.SP to 4.SP) can be stored in EEPROM for data retention purposes at power off.
Page 175: C4.2 Remote Set Point
C4-3 C4.2 Remote Set Point Any one of the pre-defined set points (1.SP to 4.SP) or a remote set point (RSP) can be selected as the control set point (CSP). The RSP signal is intended to be updated continually (for example, as a ramp signal from the CPU module) and hence, is not stored to the EEPROM when updated.
Page 176: C4.3 Limiting The Set Point
C4-4 C4.3 Limiting the Set Point You can set upper limit and lower limit for the control set point (CSP). This feature is useful in situations where it is desirable to limit the control set point within a certain temperature range, depending on the characteristics of equipment and materials involved.
Page 177: C4.4 Setting Sp Gradient
C4-5 C4.4 Setting SP Gradient To prevent drastic changes in the Control Set Point (CSP), or to vary the CSP at a fixed rate, you can set the SP Up Gradient (SPR.UP) or SP Down Gradient (SPR.DN) parameters. Use the SP Up Gradient (SPR.UP) parameter to specify the rate of change in the increasing direction.
Page 178 C4-6 Example specifying SP Up Gradient (SPR.UP) This example illustrates the use of the SP Up Gradient (SPR.UP) parameter (see Figure C4.3). The system is operating with 1.SP and then switched to 2.SP. The CSP rises at a fixed rate. In the following example, the temperature difference between 2.SP and 1.SP is 140ºC, and it is desired to achieve this temperature change in 2 minutes.
Page 179: C4.5 Pv Tracking
C4-7 C4.5 PV Tracking The PV tracking function first makes the CSP temporarily the same as the current PV value, and then changes the CSP gradually to the true CSP value according to the SP gradient setting. This function is enabled when the SP up gradient (SPR.UP) or SP down gradient (SPR.DN) parameter is set to a non-zero value.
Page 180: C4.6 Sp Tracking
C4-8 C4.6 SP Tracking When a loop is switched from remote to local mode, the SP tracking function automatically sets the selected Set Point (n.SP) in local mode to the value of the Remote Set Point (RSP) immediately preceding the switchover. SP tracking can be used to prevent a drastic change in the CSP when switching from remote to local mode.
Page 181: C5 Auto-Tuning Function
C5-1 C5. Auto-Tuning Function There are two types of auto-tuning, namely, dynamic auto-tuning, where the module performs tuning automatically, and (normal) auto-tuning, where the module performs tuning when instructed by parameters. C5.1 Dynamic Auto-tuning Dynamic auto-tuning is a control function where the module observes the movements of the measured values and output values, and automatically determines the optimal PID values when it begins operation or when hunting occurs in measured values.
Page 182 C5-2 Dynamic auto-tuning does not operate when any of the following conditions is true. When Dynamic auto-tuning Enable (SELF) is set to “0: Disabled” When Control Type Selection (OT) is not set to “0: PID Control” When Zone PID Selection (ZONE) is set to “1: Enabled” When Run/Stop Selection (RUN/STP) is set to “0: Stop”...
Page 183: C5.2 Auto-Tuning
C5-3 C5.2 Auto-tuning The auto-tuning function automatically measures the process characteristics, and then calculates and sets the optimal PID constants. When auto-tuning is activated after SP is set, the control output value temporarily assumes the form of on/off steps such that PV oscillates around SP, and the module automatically calculates the optimal PID constants from the response data.
Page 184 C5-4 Auto-tuning does not run if any of the following conditions is true. When Control Type Selection (OT) is set to “1: On/off control” or “3: Heating/cooling on/off control”. When Run/Stop Selection (RUN/STP) is set to “0: Stop”. When Automatic/Manual/Cascade Selection (A/M/C) is set to “1: Manual” when not in cascade controller mode.

C5-5 C5.2.1 Tuning Points and Stored PID Number Setting the Start Auto-tuning (AT) parameter to an integer value ranging from 1 to 5 starts auto-tuning. Setting AT to 1, 2, 3 or 4 performs tuning for 1.PID to 4.PID respectively. Setting AT to 5 performs auto-tuning for 1.PID to 4.PID sequentially.
Page 186 C5-6 Figure C5.3 Auto-tuning with Zone PID When Zone PID Selection (ZONE) is 1 (Enabled), the tuning point is automatically calculated and auto-tuning is performed. To avoid exceeding the temperature limits of the controlled object, you can set upper and lower range limits. The upper and lower range limits are RH and RL for thermocouple/RTD input, SH and SL for direct voltage input, and PRH and PRL for two-input changeover control.
Page 187: C6 Control And Computation Function
C6-1 C6. Control and Computation Function C6.1 Forward Operation and Reverse Operation Forward operation or reverse operation defines the direction of change (increase or decrease) of the control output value corresponding to a positive difference between the CSP and PV. (Switching between forward operation and reverse operation is, however, not available in Heating/Cooling Control mode.) You can switch between forward operation and reverse operation even in Run mode.
Page 188: Proportional Band
C6-2 C6.2 Proportional Band  Difference Between On/Off Operation and Proportional Operation In on/off operation, the control output alternates between “ON” and “OFF” depending on whether the deviation is positive or negative. In proportional operation, the control output varies in direct proportion to the deviation, scaled by the value of the Proportional Band (PB) parameter.
Page 189 C6-3  Adjusting the Proportional Band When fine-tuning a proportional band obtained from auto-tuning, or when adjusting the proportional band manually, note the following points. Always adjust downwards from a larger value to a smaller value. If oscillations appear, it means that the PB setting is too small. Adjusting the proportional band will not eliminate the offset.
Page 190: Integral Time And Manual Reset Values
C6-4 C6.3 Integral Time and Manual Reset Value  About Integral Time A function that automatically reduces the offset (steady state deviation) that would theoretically be unavoidable in a proportional operation is called an integral action (I action), with the integral time (TI) parameter defining the sensitivity of the integral action. The integral action increases or decreases its output continuously in proportion to the integral of the deviation (the product of deviation and its duration).
Page 191 C6-5  Adjusting the Integral Time When adjusting the integral time manually, note the following points: The adjustment is primarily for reducing the offset. Always adjust downwards from a longer time to a shorter time. When reducing the proportional band, appearance of long periodic oscillations indicates that the proportional band is too short.
Page 192: C6.4 Derivative Time
C6-6 C6.4 Derivative Time  About Derivative Time If the time constant or lag time of the controlled object is too long, proportional action or proportional integral action alone may not provide a fast enough corrective operation, often resulting in overshooting. One way to improve controllability is to take into account the tendency of the deviation (whether increasing or decreasing) and trigger appropriate corrective action earlier.
Page 193 C6-7  Adjusting the Derivative Time When adjusting the derivative time manually, note the following points: Adjust upwards from a shorter duration to a longer duration. Appearance of short periodic oscillations indicates that the derivative time is too long. A longer derivative time strengthens the corrective action and causes oscillations in the output.
Page 194: C6.5 Manual Adjustment Pid Constants
C6-8 C6.5 Manual Adjustment of PID Constants The following formula shows the relationship between the output and the PID constants. Bear this formula in mind when adjusting PID constants manually. To perform manual adjustment of PID constants, follow steps (2) to (5) given below. Procedure for adjusting PID constants manually Output = ...
Page 195: C6.6 Pid Control Mode
C6-9 C6.6 PID Control Mode This module provides 2 PID control modes, namely, Standard PID Control mode and Fixed-point Control mode, which are selectable using the Control Mode (CMD) parameter. In either control mode, either PV Derivative Type PID Control Method or Deviation Derivative Type PID Control Method is adopted depending on the operating mode.

C6-11 C6.7 “Super” Overshooting Suppression Function The “Super” overshooting suppression function uses fuzzy logic to suppress overshooting. It is particularly effective in the following situations when used together with the auto-tuning function. For suppressing overshooting For reducing start-up time For handling large load fluctuations For handling frequent changes in SP values The “Super”...
Page 198: C6.8 Anti-Reset Windup
C6-12 C6.8 Anti-reset Windup The anti-reset windup function suppresses overshoot, which tends to develop right after PID control operation begins. The function is triggered when the control output reaches its upper (OH) or lower (OL) limit. It runs in two modes, namely Automatic and Manual, which can be selected using the ARW parameter.
Page 199: C6.9 Pid Selection Method (Sp Number Selection, Zone Pid Selection)
C6-13 C6.9 PID Selection Method (SP Number Selection, Zone PID Selection) Either SP Number Selection or Zone PID Selection can be selected as the PID selection method using the Zone PID Selection (ZONE) parameter. Setting Zone PID Selection (ZONE) to “0: Disabled” selects the SP Number Selection method.
Page 200: C6.9.1 Sp Number Selection
C6-14 C6.9.1 SP Number Selection Setting the Zone PID Selection (ZONE) parameter to “0: Disabled” selects SP Number Selection as the PID selection method. The SP Number Selection method switches the set point (1.SP to 4.SP) and the PID parameter group concurrently. It is used in batch control where the set point and PID values are to be changed at the same time.
Page 201: C6.9.2 Zone Pid Selection
C6-15 C6.9.2 Zone PID Selection Setting the Zone PID Selection (ZONE) parameter to “1: Enabled” selects Zone PID Selection as the PID selection method. The Zone PID Selection method switches between PID parameter groups automatically depending on the PV value. It can be used in chemical reaction apparatus where the chemical reaction gain changes with temperature.
Page 202 C6-16  Zone Switching Hysteresis The Zone Switching Hysteresis (RHY) parameter can be used to define a hysteresis when switching between zones. Zone switching hysteresis comes into play when the Current PID Number (PIDNO) parameter is reduced, say, from 3 to 2, or from 2 to 1. It also applies when operation is switched from PID parameter group 1, 2 or 3 to group 4, according to the Reference Deviation (RDV) parameter.
Page 203 C6-17  Reference Deviation The Reference Deviation (RDV) parameter allows you to switch between PID parameter groups according to the magnitude of the deviation. When the difference between the PV and CSP is larger than the value of the Reference Deviation (RDV) parameter, the PID parameter group intended for large deviations is selected (PIDNO = 4).

Page 205: C7 Operation Control
C7-1 C7. Operation Control C7.1 Run/Stop Switch Setting the Run/Stop Selection (RUN/STP) parameter to “0: Stop” stops PID computation, and outputs the preset output. The preset output is output as is, unconstrained by the upper and lower output limits. The output rate-of-change limit is also disabled in Stop mode.
Page 206: C7.1.1 Operation After Switching From Stop Mode To Run Mode
C7-2 C7.1.1 Operation after Switching from Stop Mode to Run Mode When OT = “0: PID Control”: In general, the switch is “bump-less” on the control output value. However, if the preset output is beyond the upper and lower output limits (OH, OL), the output value bumps to a value limited by OH and OL.
Page 207 C7-3 When OT = “2: Heating/Cooling PID Control”: The control output value and the cooling control output value bump to 0.0%. However, if the Dead Band (DB) is negative, the control output value may bump to a value other than 0.0% (defined by the setting).
Page 208: C7.2 Automatic/Manual Switch
C7-4 C7.2 Automatic/Manual Switch Setting the Automatic/Manual/Cascade Selection (A/M/C) parameter to “1: Manual” allows you to output any arbitrary value manually. Manual output operates only when the Run/Stop Selection (RUN/STP) parameter is set to “Run”. If “Stop” is specified, the preset output is output instead.
Page 209: C7.2.1 Operation After Switching From Manual Mode To Automatic
C7-5 C7.2.1 Operation after Switching from Manual Mode to Automatic Mode When OT = “0: PID Control” or OT = “2: Heating/Cooling PID Control”: The switch is “bump-less” on the control output value. Control and computation begins with the output value immediately after the switch as the origin (if Integral Time (TI) is set to “0: OFF”, the control output bumps to the new value).
Page 210: C7.3 Remote/Local Switch
C7-6 C7.3 Remote/Local Switch You can use the Remote/Local Selection (RMT/LOC) parameter to switch between Local mode and Remote mode. In Local mode, one of the preset Set Point parameters (1.SP to 4.SP) is used as the set point. For details, see Section C4.1, “Set Point (SP).” In Remote mode, an external value that is obtained and written to the Remote Set Point (RSP) parameter is used as the set point.
Page 211: C7.4 Automatic/Manual/Cascade Switch
C7-7 C7.4 Automatic/Manual/Cascade Switch Automatic/Manual/Cascade switching is enabled only in cascade control. Setting is performed using the Automatic/Manual/Cascade Selection (A/M/C) parameter of the even-numbered loop. Figure C7.10 shows the mode transition diagram. Figure C7.10 Switching Modes Table C7.6 Operating Status and Input Relays in Cascade Control Odd-numbered Loop Even-numbered Loop A/M/C...
Page 212: C7.4.1 Cascade Mode
C7-8 C7.4.1 Cascade Mode In cascade mode control, the output value of the primary loop is used as the set point of the secondary loop. The primary loop uses the control set point (CSP1) of the odd-numbered loop and the process value (PV1) of the odd-numbered loop to perform control and computation (PID1) of the odd-numbered loop.
Page 213: C7.4.3 Manual Mode
C7-9 C7.4.3 Manual Mode In Manual mode, you can output any arbitrary value. The secondary loop outputs as control output values (OUTPUT2) the values of the manual output (MOUT and MOUTC) parameters of the even-numbered loop. The PV2 and CSP2 values of the secondary loop, as well as the primary loop have no effect on control.
Page 214: C7.5 Preset Output Function
C7-10 C7.5 Preset Output Function When the Run/Stop Selection (RUN/STP) is set to “Stop”, the values of the Preset Output (POUT, POUTC) parameters are output as the control output values. These values are also output when a burnout or AD converter error is detected provided the Automatic/Manual/Cascade Selection (A/M/C) parameter is set to “Automatic”...

C8-6 C8.2 Wait Function When the wait function is specified, the alarm function is temporarily disabled (enters wait state) for a specified period after the following events: - Power up - Change in SP number (SPNO) Figure C8.2 below shows an example of the alarm function when the alarm type is set to Lower Limit with Waiting.
Page 221: C8.3 Alarm Delay Timer
C8-7 C8.3 Alarm Delay Timer The alarm delay timer function delays the generation of an alarm. The alarm turns on only if the alarm condition persists until a delay timer times out. If an alarm condition disappears before a delay timer times out, the timer resets. Changing the alarm type or powering down also resets the delay timer.

C9-1 C9. Disable Backup Function The Disable Backup Function (NBKUP) can be used to suspend the automatic storing of parameters to the EEPROM. Use this function to protect the EEPROM if parameters are updated frequently. The module has two types of parameters: stored and non-stored. Stored parameters preserve their data in EEPROM even when the module is powered down provided NBKUP is set to 0 (backup).

If you observe any of the following error phenomena, follow the troubleshooting instructions described in the corresponding text sections given on the following pages: (1) Input does not change, or fluctuates excessively.
Page 236: Input Does Not Change, Or Fluctuates Excessively
D2-2 (1) Input does not change, or fluctuates excessively If input does not change, or fluctuates excessively, there may be a problem with sensor connection, module usage, or register preset values. Follow the steps below to locate the cause. Also see (3), "The loop is out of control (with an oscillating response)" if the module is used as a controller.
Page 237: Any Led Indicator Other Than Rdy And 60 Hz Is Lit Or Flashing
D2-3 (2) Any LED indicator other than RDY and 60 Hz is lit or flashing If any LED indicator other than the RDY and 60 Hz LED indicators (e.g. ALM or ERR LED indicator) is lit or flashing, an alarm or error has been detected. An input circuit may be incorrectly connected, or the self-diagnosis function may have detected an internal error.
Page 238: The Loop Is Out Of Control (With An Oscillating Response)
D2-4 (3) The loop is out of control (with an oscillating response) If the loop is out of control (with an oscillating response), it may be due to an improper value in an operation control, input, control or output parameter. Follow the steps below to locate the cause.
