Table 7-27. BLOCK _ERR
Conditions
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 Local override.
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.
Out of Service (O/S)—The block is not processed. The OUT status is set to
Bad: Out of Service. The BLOCK_ERR parameter shows Out of service.
You can configure the Man, Auto, Cas, and O/S modes as permitted modes
for operator entry.
