Issue
IO Scanning is needed when using the M340.
Product line
Unity Pro, M340
Resolution
The embedded Ethernet port on the processors (BMXP342020 or BMXP342030) does not support IO scanning.
I/O scanning with the M340 can only be done through a communications module.
Using either a BMXNOE0100, BMXNOE0110 or BMXNOC0401 is required for IO Scanning with all M340 models.
