*: Channel configuration setup for 1 measurement only. This applies to
all Input Types.
•
The second measurement on open circuit detection occurs every 3
seconds which will take 23 ms per enabled channel.
Module update rate is proportional to the channels enabled and it is also affected
by the open circuit detection enable bits. The following table indicates maximum
module date rate with all channels enabled, and all channel open circuit detection
bits enabled.

3.9.1 Module Specific Hardware Errors

A Micro850 or 870 PLC can generate a series of 0×F2xy error codes specific to
an Expansion I/O module. The Fault code is 0×F29z, where z indicates the slot
number of the expansion I/O. If z=0, then the slot number cannot be identified.
