Modes
The DO block supports the following modes:
D Manual (Man)—The block output OUT_D [9] value may be entered manually.
D Automatic (Auto)—The block algorithm uses the local set point SP_D [8]value to determine OUT_D [9].
D Cascade (Cas)—The block uses a set point supplied by another function block.
Note
The transducer block must be in Auto for the mode to go to AUTO, CAS or MAN.
D RemoteCascade (RCas)—The block uses a set point supplied by a host computer.
D Out of Service (OOS)—The block is not processed and the output is not transferred to I/O. The BLOCK_ERR [6]
attribute shows Out of service.
