Productivity Suite Simulator Modbus TCP Protocol

I am trying to communicate Modbus TCP from a C-More Micro to the Productivity Suite Simulator and receiving the following error code:

P499:Recv.ErrCode0090

This code is not listed for the productivity PAC, but it is for the AB driver and says:

Remote node cannot buffer command.

Communication works when I use the Productivity Ethernet Driver, but I want to use the Modbus Driver so additional equipment can be tested.

Thank you,

Garry

    Hey Gary,

     

    Using the Simulator I set up a simple one rung ladder project talking Modbus TCP to a Cmicro EA3-T6CL and all worked as expected. See attached projects.

      I did the same. Works. (P3-550 / EA3-6TCL / EA-ECOM)

      Garry, Can you post both project files?

       

      Or maybe mcve project files.

      Thanks for the followup. I have tried the sample program provided and it worked correctly. This is on a different computer than the one that gave me the error message.

      I will go back and try again with the original equipment. This looks like an internal issue.

      What I am doing is connecting this to Factory IO. When it didn't work I tried a C-More Micro.

      Thanks Again,

      Garry

    Thank you for the follow up!

    I have been able now to communicate with Factory IO.

    The issue was within Factory IO and assigning the Modbus inputs and outputs.

    Here is the configuration of the Factory IO Modbus TCP/IP Client.

    Factory IO Modbus Driver 2The read digital is on the coils and the read register is with holding registers. The digital outputs are offset by 11 which is the amount of the inputs required. This is because they come from the same area.

    Factory IO Modbus Driver 1Here is the Pick and Place using the Do-More Simulator and Factory IO.

     

    Thanks again for the assistance.

    Garry
