Download finished example program "SIMATIC 400 Station2 (C)"
Procedure
We recommend you use the example "SIMATIC 400 Station2 (C)" of the FM_PIDEx project
for the next tests. As a result you can try out the FM 455 C on a simulated control section
without using real processes (refer to the
FM 455 Controller Module manual, chapter
"Application example for the FM 455 C").
1. In HW Config, replace your FM 455 C with the FM 455 C of the example.
2. In the HW Config, check the cyclic interrupt clock cycle of the OB 35. 100 ms must be set
as the execution time.
3. Safe, compile and download this configuration.
4. Copy all blocks, except system data and the SFCs 58 and 59, from the blocks container
of the sample project to the blocks container of the user program.
5. Check the module address setting at the MOD_ADDR parameter of DB 31. It must tally
with the FM 455 C address that is entered in the HW Config.
6. Download those blocks to the CPU.

Testing the controller test using the loop monitor and curve recorder
functions
Procedure
You open the loop display in the parameterization interface by opening online Test > Loop
display in the FM 455 C of the example program. The loop monitor lets you manually enter
setpoints and manipulated values to test the controller.
To open the curve recorder, call instance DB 31 of the example program by selecting
Test > Curve Recorder in the FM 455 C programming interface. You can use the curve
recorder to record the trend of a setpoint step, for example.
For further information on the loop monitor and curve recorder, refer to the Online Help (click
Help in the relevant view.)
Note
You toggle from PG setpoint mode to PG manipulated value mode by setting the
SP_OP_ON, SP_OP, LMNOP_ON and LMN_OP variables at FB 31 PID_FM. Those
variables are reserved for this specific function and should not be implemented in the user
program.
