Manual (Man) — The block output (OUT) can be set manually.
Remote output (ROut) — The OUT is calculated by an application that writes to the ROUT_IN parameter.
Automatic (Auto) — The SP can be set manually and the block algorithm calculates OUT.
Cascade (Cas) — The SP is calculated in another block and is provided to the Fuzzy Logic Control function block through the CAS_IN connection.
Remote cascade (RCas) — The SP is calculated by an application that writes to the RCAS_IN parameter.
Local override (LO) — The track function is active. OUT is set by TRK_VAL. The BLOCK_ERR parameter shows Local override.
Initializing 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 (OOS) — 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, RCas, ROut and OOS modes as permitted modes for operator entry.
