Multiple slave FCs [ERROR 153]

Multiple slave FCs [ERROR 153]

Multiple slave FCs on Module 1,01,02 slave 3: see slave report (Module 1,01,02 Header) for details

This message means that DBDOC's analysis of the configuration of your slave FC specs suggests that there may be a problem with too many slaves chained together or with more than one slave on the same channel.

In the example, you can see that Channel 17 has a problem. Two pairs of DIGRP: Digital Input Group [FC84] blocks (blocks 720/730 and 740/750) have the same slave address 17. 18 and higher are unused, so the solution probably involves configuring the second pair to be the next slave.
