  1. 3G3JX communication to ACS550 (ABB's inverter)

    Linhvct replied to Linhvct's topic in Omron

    it's strange to a newbie using PLC like me. I read the manual and it said the frequency referency register is 40001, so I write these follow value into Modbus fixed DM: D1304 : 4000 D1305 : 1XXX D1306 : X000 X means the frequency value in binary, then the number of data bytes is 5, is that right?

  3. Thank PMCR, wiring, DIP switch in JX and CP1W-CIF11 are just the same as your picture, but it still doesn't work. May be I set up JX's parameters wrong. I can not find what I did wrong. In PLC's programme, setting page, tab Port 2, I set "serial gateway" and baud speed is 9600 with 1,8,1-N. Is there something else that I miss?
  4. Eck, Just codes 03 and 10 is used to read and write registers. May be I find out what I made wrong. Many thanks for you supports.
