Is there a standard PCSD template which can control two digital outputs (Fans) to control a temperature at a given setpoint?
Hi Stuart, as far as I am aware PSCD does not include what you want as standard, but could be achieved using PCSD building blocks. This might have changed with the latest releases of PCSD (I only have v5 and no longer work for Emerson so don’t have access to the latest version).
What Version are you on?
In reply to Carl Stanford:
PCSD has a module _O_GAP_52 (or 53, depending on version) that operates a discrete device based on comparing a PV from an external analog module with either single or dual thresholds. If the PV is above the high threshold or the setpoint plus a bandwidth, it changes the setpoint of the discrete device. If the PV is below the low threshold or the setpoint minus a bandwidth, it changes the discrete device to a second setpoint. The module can be set for direct or reverse action.
