  3. Echo back setting on QJ71C24n - R4

    It's unlucky that I am not able to change my wiring to RS422, it must be Rs485. I am now trying Pre-defined protocol to do the Modbus rtu. Follow your advise, I looked for code to ignore echo back in MELSEC-Q manual, chapter number 8: " DATA COMMUNICATION USING THE PRE-DEFINED PROTOCOL" but It may be not here. Would you please give me some idea or keyword about this code for I can find it easier. Thank you so much for your help.
  4. Hi everybody. I have 1 QJ71C24n-R4 with 2 channels CH1 & CH2 and I want to use Modbus RTU for both of channels to read data from electric meter. Now I can do it well with CH2 but cannot with CH1. The reason is echo back setting, my GX work 2 only able to prohibit echo back on CH2, not able on CH1. Does anyone know about this problem? Please give me some advise. Thank you so much.
