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).
