Interface with the PMC area
For the number interface
A text message is displayed on the operator’s panel via the 1- or
2-byte text number report interface, using the R or D or
E(PMC-SB7)area of the PMC. If the text number is zero, the
character previously displayed will be erased. Subsequently, the
system monitors for a number change, and displays a text
message only if a change is made. The system monitors for a
number change periodically and, therefore, a number change
must be retained for 500 msec or longer. If a change cannot be
detected, the message cannot be displayed.
