Remote I/O Systems
SR 25312 turns ON to indicate an error has occurred in Remote I/O Sys-
tems. The ALARM/ERROR indicator will flash, but PC operation will continue.
SR 251, as well as AR 0014 and AR 0015, contain information on the source
and type of error. The function of each bit is described below. Refer to Optical
and Wired Remote I/O System Manuals for details.
If there are errors in more than one Remote I/O Unit, word 251 will contain
error information for only the first one. Data for the remaining Units will be
stored in memory and can be accessed by turning the Error Check bit ON
and OFF. Be sure to record data for the first error, which will be cleared when
data for the next error is displayed.
Not used.
