Card being used. These 3 parameters must match the PLC you are communicating to.
6. Select the Comms Mode. Unconnected (UCMM) messaging relies on shared resources to
transfer data to/from the PLC. This could result in message timeouts if there are a lot of devices
fighting for these shared buffers. Connected (Class 3 Explicit) messaging relies on reserved
resources to transfer data to/from the PLC. Connected messaging is recommended.
