Modes
The PID function block supports the following modes:
•
Manual (Man): The block output (OUT) may be set manually.
•
Automatic (Auto): The SP may be set manually, and the block algorithm
calculates OUT.
•
Cascade (Cas): The SP is calculated in another block and is provided to the PID
block through the CAS_IN connection.
•
RemoteCascade (RCas): The SP is provided by a host computer that writes to
the RCAS_IN parameter.
•
RemoteOutput (Rout): The OUT is provided by a host computer that writes to
the ROUT_IN parameter.
•
Local Override (LO): The track function is active. OUT is set by TRK_VAL. The
BLOCK_ERR parameter shows Out of service.
•
Initialization Manual (IMan): The output path is not complete (for example, the
cascade-to-slave path might not be open). In IMan mode, OUT tracks
BKCAL_IN.
