Input Channel Status
The slave maintains a fixed area in the dual port RAM to store
the current value and status of each channel. The master MFP
reads the data and status for each channel individually.
To view the status of the IMASI03, read it's block output N+1 of
function code 215. Check the input status on each point indi-
vidually by looking at the corresponding function code 216
block output quality. Use any INFI 90 operator interface, such
as an Operator Interface Station (OIS) or Engineering Work
Station (EWS).
Slave Errors
Slave errors are reported to the MFP through function codes
215 for the slave and 216 for the active input channels. The
MFP indicates slave errors through module status when in the
execute mode. Byte 1 of the module status will indicate an
error and byte 2 of the module status will indicate LIO (local
I/O) when there is an IMASI03 error.
When specification 4 in function code 215 is set to 1, the MFP
will continue to execute if function code 215 detects an error. A
module problem report can be requested in order to get specific
information about any slave error indicated in module status.
When specification 4 in function code 215 is set to 0, the MFP
goes into error mode if function code 215 detects an error. If an
error occurs, module status byte 1 will indicate an error, byte 2
will indicate LIO and byte 3 will indicate the specific error.
Refer to Table
. For example, Analog Input Reference Error
is indicated by a 2 and Missing I/O is indicated by a 3 in
byte 3.

Error
The indicated FC 215 block failed due to
an IMASI03 A/D system reference error.
Remove IMASI03 and insert. If error
recurs, replace the IMASI03.

Missing I/O
The indicated FC 215 block failed due to
a communication error with the
IMASI03.
Remove IMASI03, verify expander bus
dip shunt, verify IMASI03 slave address
is same as FC 215 Spec 1. Insert
IMASI03 and verify proper seating. If
error recurs, call Bailey field service.
The indicated FC 215 block detected an
IMASI03 error. (IMASI03 slave firmware
has reported an error.)
