Addressing MNB-1000-15 remote I/O modules

Issue

The inputs and outputs from the remote I/O modules either show as NA or do not function properly.

Product Line

TAC I/A Series

Environment

MNB-1000 installations with MNB-1000-15 remote I/O modules

Cause

In this case the dip switches on the remote I/O modules were set to 2 and 3 incorrectly because it was assumed the MNB-1000 was address 1. 

The MNB-1000's address relative to the remote I/0 modules is 0 and cannot be changed.  The remote I/O modules must be addressed 1 through 8. 

Resolution

Adjust the dip switch settings on each remote I/O module to address them from 1 up to 8.
