Can I monitor IO module health in an M340 application?

Yes, you can monitor the health of an IO module. Unity offers %SW160 - %SW167 for this purpose. Each bit within the word will represent a module location along the bus. For example %SW160.3 would be contain the health status of rack 0, slot 3. If the bit value is "1" the module is healthy, if the bit value is "0" the module is unhealthy.
