For information on other features, engineering, design, construction work, startup and maintenance of PROFIBUS PA, refer to the PROFIBUS PA Nutzerorganisation e.V. website: www.profibus.com Internal Structure of FLXA21 The FLXA21 contains a structured mapping of function blocks. Each function block serves a specific task. Physical block • Manages the status of FLXA21 hardware. • Automatically informs the host of any detected faults or other problems. Transducer block • Converts sensor input to process values which are transferred to AI function block by...
Parameters Figure 1.1 Logical Structure of Each Block Node address, block tags and contained parameters within a function block are structured in the FLXA21 device as shown in figure 1.1. 1.3 Wiring System Configuration The number of devices that can be connected to a single bus and the cable length vary depending on system design. When constructing systems, both the basic and overall design must be carefully considered to allow device performance to be fully exhibited.
Cable gland diagram Cables, terminals and glands for PROFIBUS Wire and install the system by referring to chapter 2 in the FLXA21 instruction manual (IM 12A01A02-01E). The PROFIBUS PA power supply is 9 to 32 V DC. The wiring is the same.

<2. Preparation> When using a SENCOM module When using a SENCOM module, you need to use the supplied cable clamp to fix the sensor cables in place. Attach the supplied cable clamp as shown in Figure 2.2. Sensor cable Cable cramp Figure 2.2 When using a SENCOM module DIP switches Figure 2.3 shows the DIP switches for setting the address and write protection. Normally, you do not have the change them from the default settings.
Figure 2.2 Shield and grounding How to download EDD for PDM It takes a certain time to insert EDD to PDM package. If your PDM package doesn’t include FLXA21 EDD, download it from the following website. http://www.yokogawa.com/an/download/an-dl-profibus-001en.htm *: This address is subject to change without prior notice. If the above address cannot be accessed, consult your nearest sales office or the agency from which you purchased the product.
Connect the devices as shown in Figure 3.1. Connect the terminators at both ends of the trunk, with a minimum length of the spur laid for connection. The polarity of signal and power must be maintained. Power supply HOST Coupler/terminator Terminator FLXA21 Figure 3.1 Cabling IM 12A01A02-72E 3rd Edition : Oct. 01, 2015-00...
Using the host device display function, check that the FLXA21 is in operation on the bus. Unless otherwise specified, the following settings are in effect when shipped from the factory. If no FLXA21 is detected, check the available address. Please set all addresses of the devices in advance or separately connect each FLXA21 and set a different address for each. Make sure to note the address after changing it as from this point on the device can only be accessed through this address.
<3. Getting Started> Notes When Using the FLXA21-SC Concentration Table (when using FieldMate) The FLXA21-SC concentration table can be read from and written to using the CONC_TABLE_ CONCENTRATION_1 to CONC_TABLE_CONCENTRATION_21 and CONC_TABLE_ CONDUCTIVITY_1 to CONC_TABLE_CONDUCTIVITY_21 parameters of the transducer block. However, when using FieldMate, note the following points. The default concentration table values are “Not a Number”. On the device screen, they appear as blank. On FieldMate, “IEEE: NOT A NUMBER” is displayed. Values set to “Not a Number” cannot be changed from FieldMate. If you want to write the concentration table from FieldMate, first set all the items in the concentration table to some value from the device screen. PRIMARY/SECONDARY/TERTIARY/ QUATERNARY_VALUE Value Assignment Measurement values are assigned to PRIMARY_VALUE, SECONDARY_VALUE, TERTIARY_ VALUE, and QUATERNARY_VALUE from the device screen.
In general, slave devices exchange data cyclically with the master (class 1, e.g. PLC). The FLXA21 (slave) gets the data from the sensor, makes some calculations and makes the outcome available through analog input blocks. The controller device (Master) requests for these process values, makes some calculation (PID, ratio) and sends the result to an actuator.
<4. Explanation of Basic Item> The AI1/2 measurement items assigned to each slot are determined according to Channel (AI) as well as PRIMARY, SECONDARY, TERTIARY, and QUATERNARY Type (Transducer Block). For details, see the description of each item. The GSD file of the FLXA21 specifies 3 modules: ;Empty module Module = “Empty Module” 0x00 EndModule ;Modules for Analog Input Module = “Analog Input (AI)short”...
The actual mode is changed by setting the target mode. When the physical block mode is set to OOS all function blocks are set to OOS mode. CHANNEL Channel is the parameter to select the signal which is calculated in SENSOR Transducer Block. The values are assigned to channels. For the FLXA21 three or four channels are available. For the FLXA21, you can select from the PRIMARY, SECONDARY, TERTIARY, QUATENARY values assigned to the Transducer Block. For details on how to assign measurement items to parameters, refer to “3.6 PRIMARY/ SECONDARY/TERTIARY/QUATERNARY_VALUE Value Assignment”.

<4. Explanation of Basic Item> Fail Safe Mode (FSAFE_TYPE) Fail Safe Mode is parameter used to define the reaction of the device, if a BAD status of signal to AI function block (OUT.Status and OUT.Value) is detected. This is available only when Target Mode of AI function block is in “Auto”. Fail Safe Mode defines the Output Value and Status (Quality) when status of input signal to AI function block is BAD. This function is valid only when Actual Mode of AI function block is in “AUTO” Table 4.3 Fail Safe Mode (Classic Status) Fail Safe Mode...
<4. Explanation of Basic Item> Setting and change of basic parameters This section describes the procedure taken to set and change the parameters for each block. Obtaining access to each parameter differs depending on the configuration system used. For details, refer to the instruction manual for each configuration system. Access the block mode (MODE_BLK) of each block. Set the Target of block mode (MODE_BLK) to Auto, Man or O/S (*Note 2) according to the Write Mode of the parameter to be set or changed.
The default value is 0.0 to 100.0%. Change this if necessary. For AI1 set L_TYPE to Direct With the FLXA21, the channel values are displayed on the display indicator, independent of the scaling in the AI blocks. Setting the output mode Access the L_TYPE parameter. Set the output mode.

<5. In-Process Operation> M (Maintenance): An alarm category for a detected failure that has a low level of urgency but is a failure that could develop into a problem causing restrictions in instrument functionality in some environments. Classic Status and Condensed Status can be switched by using the Condensed Status/ Diagnosis (PB.COND_STATUS_DIAG) parameter.
