I/O refresh Execute I/O refresh before starting program operations. • Input ON/OFF data input from input module/intelligent function module to CPU module • Output ON/OFF data input from CPU module to output module/intelligent function module When executing constant scan, I/O refresh is executed after the constant scan waiting time ends. Program operations Step 0 of each program up to the END/FEND instruction is executed according to program settings.
Page 20: Scan Time

Scan Time The CPU module repeats the following processing. The scan time is the sum total of each process and execution time. RUN time RUN time initialization processing*1 I/O refresh Program operations Scan time END processing *1 This process is included in the initial scan time. Initial scan time This refers to the initial scan time when the CPU module is in the RUN mode.

Page 57: Chapter 9 Pid Control Function

PID CONTROL FUNCTION Outline of Function PID control is performed by PID control instruction. The PID instruction requires the system to calculate the output (MV) value from the measured (PV) value. Through combining the P (proportional) action, I (integral) action, and D (derivative) action the target (SV) value can be obtained.

• Relationship between the forward/backward operation and the output (MV), measured value (PV) and target value (SV) The relationship is as follows. Output value (MV) Target value (SV) Backward Forward operation operation Measured value (PV) Alarm setting (for input variation and output variation) If b1 and b2 in (s3) +1 are turned ON, the input variation and the output variation can be checked.
Page 63: Input Filter Constant (s3)+2

Upper and lower limits for output value When the upper and lower limit settings of the output value are valid, the output value is as shown in the chart. The upper limit and lower limit of the output value can moderate the increase of the integral item in the PID control. When using the upper limit and lower limit of the output value, make sure to set (s3)+1, b2 to OFF.
Page 64: Proportional Gain (s3)+3

Proportional gain (s3)+3 During the proportional operation, the output (MV) increases in proportion to the deviation (difference between the target value (SV) and the measured value (PV)). This deviation is called proportional gain (Kp), and expressed in the following relational expression: Output (MV) = Proportional gain (KP) ...

Integral time (s3)+4 During the integral operation, the time after deviation is generated until the integral operation output becomes the proportional operation output. This is called integral time and is expressed as "TI". As TI becomes smaller, the integral operation becomes stronger. Setting range: 0 to 32767 (...

Page 70: Auto-tuning

Auto-Tuning This chapter describes the auto-tuning function of PID instruction. The auto-tuning function will automatically set the important constants, such as the proportional gain and the integral time, to ensure optimum PID control. There are two auto-tuning methods: limit cycle method and step response method. Limit Cycle Method For acquiring satisfactory control results in PID control, it is necessary to obtain the optimal value of each constant (parameter) suitable to the control target.
Page 71

■Operation characteristics (in an example of backward operation) During the "W" period after the tuning cycle is finished, the output value is held at the output Lower Limit Value (LLV), and then normal PID control is started. The value "W" can be obtained by the expression "W = (50 + KW)/100  ( - on)", and the wait setting parameter "KW"...

Step Response Method For acquiring satisfactory control results during PID control, it is necessary to obtain the optimal value of each constant (parameter) suitable for the control target. This paragraph explains the step response method to obtain three constants in the PID control (proportional gain (KP), integral time (TI) and differential time (TD)).

Page 86: Chapter 10 Constant Scan

CONSTANT SCAN Since the processing time differs as per the execution/non-execution of command used in the program, the scan timer changes with every scan. By setting the constant scan, because a program can be repeatedly executed while keeping scan time at a specified amount of time, even when the execution time of the program changes, the I/O refresh interval can be constant.
Page 87

Conditions of setting time Set a value that meets the following relational equation for the setting time of the constant scan. "WDT setting time" > "Constant scan setting time" > "Maximum scan time of the program" When the maximum scan time of the program is longer than the setting time of the constant scan, it results in error. The constant scan time is ignored and it is executed with the scan time of the program.

LATCH FUNCTION The contents of each device/label of the CPU module is cleared in the cases described below and changed to its default value. • At power OFFON of the CPU module • At reset • A power failure that exceeded allowable momentary power interruption The contents of each device/label with latch setting will be maintained in case of power failure even in the above-mentioned cases.
Page 102: Latch Settings

14.3 Latch Settings Latch settings This subsection describes the latch setting. Setting latch on devices A range of multiple latches can be set for 1 type of device. Two latch ranges, latch (1) and latch (2), can be set. However, make sure that the range of latch (1) and latch (2) is not overlapping.
Page 103: Setting Latch On Labels

Setting latch on labels This subsection describes latch setting on labels. Operating procedure In the label edit window, specify Label edit window "RETAIN" for label attribute. There are two types of latch for labels: "Device/Label Memory Area Detailed Setting" window latch (1) and latch (2).
Page 104: Precautions

14.5 Precautions The precaution to be taken when using a latch function is described below. • When latch range and device no. of points are changed in the parameter, the latching for devices other than link register (W) and latch label will be the same as the latch settings before the change. Also, if the latch range setting parameter at the time of previous operation is different from that at the time of the current operation after the CPU module is powered OFF and ON or reset, the latch data is recovered only in the overlapping part of the latch ranges.
