Unable to configure PID output using a groov RIO or GRV-MM1001-10 channel configured as TPO


Applies To:

PAC Control Basic
PAC Control Professional

Versions Affected:

R10.5a to current


Symptoms:

If a groov RIO or a multifunction mixed-signal (GRV-MM1001-10) channel is configured with the TPO feature, you may be unable to add it as an output of a PID loop in PAC Control.

Workaround:

You can configure the PID output as Host when configuring the PID loop, and then create a new chart that moves the value using the Get PID Output and Set TPO Percent commands. 

For instructions, see “Configuring PID Loops” in the PAC Control User’s Guide (form 1700). See also the PAC Control Command Reference (form 1701).
