Proceed as follows to create the objects:

● You create a second organization block [OB200] in which you will call up the blocks of the

PID controller.

● You create the technological object "PID_Compact".

● You load the simulation block "PROC_C" to the organization block [OB200]. By using the

simulation block, you require no hardware other than the PLC.

● You configure the technological object "PID_Compact".

– Select the controller type.

– Enter a setpoint for the controller.

– Interconnect the actual value and the controlled variable of the technological object

"PID_Compact" with the simulation block "PROC_C".

● You load the user program and carry out a controller optimization in the commissioning

window of the technological window.
