Communicating with Remote I/O 6-21

Monitoring Remote I/O Scanner Channels

•Do not program IIN or IOT instructions to a module in the same physical module group as a BT module unless you know a block-transfer is not in progress. If you must do this, then use an XIO instruction to examine the .EN bit of the block-transfer instruction to condition the IIN and IOT.

To monitor channels configured as a scanner, use the scanner mode status screen in your programming software. This screen displays the data in the diagnostic file you defined on the scanner mode configuration screen (page 6-7).
