E14 Community recommendation for ModBus TCP client

colporteur

I am looking for an application to query a ModBus TCP interface on a scale head?

The company I am working for has recently installed a RiceLake 1280 scale indicator with a Modbus TCP interface. The scale indicator is IP capable and resides in a network DMZ. The goal is to have a cloud vendor pull scale data over the network from the Modbus interface. I'm looking for an application that can query the Modbus interface to confirm communication with the interface. 

The scale vendor recommended an application in order to set the Modbus TCP interface IP address. I managed to get that working, proving the interface IP answers an IP ping. DMZ rules have been set in place to isolate the indicator. I want to test that the cloud vendor can get to the Modbus interface and pull the data. I'm thinking maybe there is a software tool like minicom is for serial communication, except the tool is for Modbus.

E14 has some great Modbus resources but nothing to match my search. A Modbus client query tool. I'm hoping there is a community member that has experience with Modbus TCP and that they could recommend application software to perform the task.

  • I will close this post by first saying thank you for your input. Sounding out the problem and getting suggestions was helpful in arriving at the solution.

    I culled a link for oceancontrol windows GUI client from the link   provided.    python client established a connection, I just didn't invest in generating a query. It did confirm it was working.   input reminded me of net cat a network test tool I had used many moon ago. I confess net cat was the one I used the most.

    Since I was only looking to confirm a connection through the firewall, net cats ease of use made it ideal for quick testing. Supported on windows and linux was bonus. I had to learn the syntax for Windows:( It is not the same as linux.

    With a confirmed modbus tcp interface available it is off to configure and test a VPN end to end solution that will connect the company and vendor. Thanks again for you input.
