Any way to make a PID OUT = IN?

I will be reading the output value of a PLC for a control valve and want to use the PCSD control valve GEM to show that value. I made a new class based on CSD class, but changed the AI function block to an AI_SOFT. I am wondering if there is a way to basically make the PID block pass through the in value to the out value, so that the GEM will just show that. I don't really want to utilize the PID algorithm at all, just need that OUT value since that is what the PCSD GEM is looking at.

    There are a couple of ways to do that. One way is to allow only ROUT mode and set the mode to ROUT and wire the value to ROUT_IN, thus the PID output would follow ROUT_IN. Another way is to enable tracking in control options, turn TRK_IN_D On, and wire the value to TRK_VAL. Similar to the ROUT option, but will cause the PID block to have a question mark since track override in On.
