Supports Out of Service (OOS), Local Override (LO),
Manual (Man), Automatic (Auto), Cascade (Cas), and
Remote Cascade (RCas) modes.
The Set point (SP_D) supports the full cascade sub-
function.
Use the Cascade mode to transfer the output of
another block to the Set point (SP_D) of the DO block.
Use the IO_OPTS Invert selection to do a Boolean
NOT function between the field value and the output.
Use the IO_OPTS Invert selection to do a Boolean
NOT function between the SP_D and the output.
If the hardware supports a readback value, it is used
for READBACK_D, and, after accounting for the
IO_OPTS Invert selection, acts as the PV_D for this
block. If this is not supported, READBACK is
generated from OUT_D.
In the Man mode, an operator can force the output, in
a programmable logic controller sense. If Man mode is
not permitted, it must be supported as a transition
mode for exiting the OOS mode
The SIMULATE_D parameter is for testing purposes
only and always initializes in the disabled state.
