  • c-more and do-more H2 processor


    I am having difficulty connecting a c-more panel to the Rs-232 port on a H2-DM1E.

    I have both the serial port and the panel at 9600 baud 8 data 1 stop odd parity on a Ea-2CBL cable

    C-more software is ve 2.76 with native do-more driver.

    Keep getting a PLC-001 timeout No flashes on Tx or Rx LED

    Anyone have an idea?

    On PLC->System Configuration, CPU page, make sure the internal serial port is configured for Do-more Programming. This is the default, but I just want to make sure you hadn't tweaked it to Modbus or General Purpose or ???.
    There are 10 kinds of people in this world, those who know binary, and those who do not.

      Yes set to Do-more progrogramming

        Reset everything and now I see tx and rx blinking in unison on both the panel and plc. Still no comunucation though. PLC-001 timeout

          Have the same setup on my test bench, and couldn't get it work. Could get them to talk in K-sequence. After some tinkering found the following settings made it work for native do more protocol:

          Turn Parity to None
          Transmit Control: Unconditional
          RTS: Follows Transmitter

          I think we just found a bug in the software?

          Like clockwork, if I set the internal port of the Do-More to Odd Parity it will not talk to the C-More in Do-More protocol, but however if they are both set to Odd then it works with K-Sequence...v

            For peace of mind, I set up an H2-DME1 internal serial for Do-more/9600/8/1/Odd and connected with works fine. Have not tried it with C-more, however...

              I have C-more and DoMore both set up using the DoMore Protocol.

              I have tested with both set to:

              Baud: 9600 and 38400
              Data Bits 8
              Stop Bits 1
              Parity: None and Odd
              Transmit Control: Unconditional
              RTS Control: Follows Transmitter

              No errors, communicating with no issue.

              Using C, D, V and N memory types.

              C-more version 2.76

              DoMore Software version 1.0.2

              DoMore Hardware
              OS version 1.07
              Booter version 3.04
              FPGA version 3.3
