REMOTE I/O INTERFACE MODULE BLOCK
6-7
08 I/O Communication Error (BUSERRS) .............................................................................CWR
This diagnostic indicates that an error occurred in communication between the RIO module
and the instrument. This diagnostic can be suppressed or enabled as follows:
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block.
SUPPRESS 1 Diagnostic error is suppressed. Acknowledgement status remains
clear.
09 Unacknowledged I/O Communication Error (BUSERRU) ............................................. – WR
If the I/O communications error diagnostic is enabled, the unacknowledged diagnostic status
indicates if the diagnostic is or is not acknowledged. The status can be acknowledged or read
as follows.
NO 0 Diagnostic error is acknowledged.
YES 1 Diagnostic error is unacknowledged.
10 Active I/O Communication Error (BUSERRA) ................................................................ – WR
The active I/O communications error diagnostic status indicates if the error is active even after
acknowledgement. The status can be read as follows.
NO 0 Diagnostic error is not active.
YES 1 Diagnostic error is active.
11 Remote I/O Bus Communication Error (COMMERRS)...................................................CWR
This diagnostic indicates errors in communication or loss of communication between the RIO
interface module and the CS-31 bus. This diagnostic can be suppressed or enabled as
follows:
ENABLE 0 Diagnostic error is not suppressed and errors are reported to the
System Event block.
SUPPRESS 1 Diagnostic error is suppressed. Acknowledgement status remains
clear.
12 Unacknowledged Remote I/O Bus Communication Error (COMMERRU)................... – WR
If the remote I/O bus communications error diagnostic is enabled, the unacknowledged status
indicates if the diagnostic is or is not acknowledged. The status can be acknowledged or read
as follows.
NO 0 Diagnostic error is acknowledged.
YES 1 Diagnostic error is unacknowledged.
13 Active Remote I/O Bus Communication Error (COMMERRA) ...................................... – WR
If the remote I/O bus communications error diagnostic is enabled, the active status indicates if
the error is active even after acknowledgement. The status can be read as follows.
NO 0 Diagnostic error is not active.
YES 1 Diagnostic error is active.
