What is the maximum Modbus port speed on the M340 CPU?

Issue:

Need to confirm the maximum supported baud rate for the embedded Modbus port on Modicon M340 CPUs.

Product Line:

Modicon M340 CPUs with embedded Modbus ports (examples include: BMXP341000, BMXP342000, BMXP342010, BMXP342020)

Environment:

Using the embedded Modbus port on an M340 CPU

Configuring Modbus serial communications (baud rate)

Cause:

The embedded Modbus serial interface on M340 CPUs has a defined maximum communication speed that limits the highest configurable baud rate.

Resolution:

The maximum Modbus port speed is 38,400 baud on all M340 CPUs with embedded Modbus ports (e.g., BMXP341000, BMXP342000, BMXP342010, BMXP342020).
