hi all,
i am testing communication between CQM1H-SCB41 to inverter 3G3MV (RS422). but have a error CAL from inverter when i set parameter n003 = 2 and n004=6.
i setting port B of PLC (please see attach file) and inverter :
N002= 0
N003= 2
N004= 6
N151 =0
N152 =1
N153= 1
N154 =3
N155 =2
i don't know use instruction to program (TXD and RXD or PMCR) and my configuration is correct and use PMCR instruction ?
please show me or send me code program use cx-programmer to write frequency from PLC CQM1H to inverter 3G3MV and read frequency from inverter to PLC
thanks everyone so much.
i am hearing from everyone soon.
best regards,
