REMOTE I/O INTERFACE MODULE BLOCK

6-9

20

I/O Module Mismatch (MODMM).......................................................................................– – R
Even though the I/O mismatch diagnostic may be suppressed and its value not stored with the
active I/O mismatch attribute, the actual I/O mismatch condition can still be determined by this
attribute (value is unsuppressed). This attribute is used to determine if there is an I/O
mismatch when changing the I/O mismatch diagnostic from suppressed to enabled.

NO

0

Diagnostic error is not active.

YES

1

Diagnostic error is active

21

Slots (SLOT) ...................................................................................................................... C – R
The slot (module location) number of the Remote I/O Interface Module is read as the lower of
the two slot numbers (1=1-2). Two numbers are displayed for configuration purposes (1-2, 2-
3, 3-4... through 31-32) because the module is double wide (note that locations 14-15F and
18-19F indicate they are valid only for the flush mount form of the Modcell processor).

22

Module Identification (MODID) ........................................................................................– – R.
The RIO module identification number, in hex, as read from the module. Currently only
FB0000.

23

Extended Error (EXTERR) ............................................................................................... – WR
The error code as read from the RIO module. Presently not supported.

30

Bus Error Counter (BUSERRCT) ..................................................................................... – WR
Wrap-around counter which provides a free running count (0 to 65535) of the quantity of CS-
31 bus communication errors. (Errors in communication between the RIO module and the
instrument are counted in Interface Block Attributes 132 - MDNORSPS and 133-
MDCHKSMS.)
