Result

You have loaded in the example project the block for the simulation of the input and output

values of the PID controller.

When the cyclic interrupt OB "PID (OB200)" is executed, the "PROC_C" block simulates

input and output values and loads these in the instance data block "PROC_C_DB". The

values of the parameters INV and OUTV are mapped in the tags when the program is

executed.

In the next section you will use the technological object "PID_Compact" to configure the PID

controller and link its inputs and outputs to the corresponding values of the simulation block.
