  1. Hi PMCR,

     

    I'm working with an OMRON CP1L-L with the CP1W-CIF12 RS-485 Serial Communication Card and I want to read and write to a Filler Conrtroller of Micromotion, model 1500 with the option of Modbus RTU. I verified the Micromotion with Simply Modbus Master and I can read and write to some register without any problem.

    I setup the Serial Port 1 on the OMRON to Serial Gateway with all the same parameters of the Comm setting on the Micromotion. When I entered the values in the DM32300, 32301, 32302 and 32303, I force the bit A0640.0 at ON and I saw the light coming on momentarily. The bit at A0640.02 turned ON after few seconds and the value at the DM32352 get 0080 for timeout. Does that mean that I only have to increase the Time Response on Serial Port 1 ?

    Plus, do you know if there's a Modbus Slave Function Block for the comm RS-485?  I think that I need to use the CRC16 FB ?

    Regards,
