Remarks SP (SP_D) is normally written by an operator occasionally
while in Auto mode. It is not intended to be written as a
cascade setpoint input. Instead, a connection to CAS_IN is
intended to provide a value into SP (SP_D) when in Cas
mode and a write into RCAS_IN is intended to provide a
value into SP (SP_D) when in RCas mode. However, SP
(SP_D) may be updated when operating in ROut mode in
order to provide a reasonable setpoint, if failing from ROut
to Auto mode upon a failure of the ROUT_IN update.
The data type consists of the value and status of discrete
value parameters. It uses the following two elements.
1 Status
2 Value
