Read a modbus register from a Modbus device Ethernet IP or Ethernet Tcpip

Greetings

I have a Laumus Load cell transmitter controller. It is configured as Ethernet/IP

I am unable to read the modbus registers from it via the IP port on the click.

Hooked it to Rs-485 and all running however the boss wants to us the network.

I can order the device configured as Ethernet/IP, Ethernet TCP/IP ,Modbus/TCP

AS stated I could not get the click to read the registers on the Ethernet/IP version.

Can Click read the modbus registers on the TCP/IP version?

Thanks

Tim

    Hi Tim,

     

    If your unit is currently configured for Ethernet/IP then most likely there is no Modbus TCP driver running in the transmitter. You would need to order a unit configured for Modbus TCP unless the transmitter is software configurable allowing you to select a different driver.

     

    The Click does not support acting as an Ethernet/IP scanner (master) which is what you would need to be able to talk to the transmitter (would be the 'adapter' or slave).

     

    For Modbus TCP, the Click would be the client (master) and the transmitter the server (slave).
