MCW151 and 3G3MV. Communication errors?

1 post in this topic

Hi All! My set OMNUC+MCW151-> port RS-422( twisted pair cables)-> two 3G3MV. Servo and inverters in stop mode. Use programs from mc151coms.zip from folder Modbus (Mechatronics application center). Has a little changed. Speed 9600. Run RAMPS.BAS (priority 3) and save log in file modbus_test.log. Reading in a cycle 24 register, usually all it is normal. But sometimes (without law) the answer I do not receive, and 3G3MV shows communications error (U-15): - CRC error – always; - Parity error, Overrun error, Framing error - sometimes (without law). At speed of 19200 mistakes is more often. The project and log-file are in the attached file modbus_test.zip You could collect the stand and execute my project during 60 minutes? modbus_test.zip
