How to Set Up Communications between an IDEC HG3G HMI set up as a Modbus/TCP Master and Acromag’s 965EN
To establish communications between an IDEC HG3G HMI set up as a Modbus/TCP master and Acromag’s 965EN Remote I/O set up as a Modbus/TCP slave.
HG3G-8 Series HMI
965EN-4006 Remote I/O
Projects for IDEC’s HG3G series of HMIs are created with WindO/I-NV2 software. To create a new program, click on the Application Menu button in the top left-hand corner of the software and select New – Interactive Quick Start
The software will prompt you to enter a file name for your project. Specify the directory in which you’d like to save the project, as well as the file name and click the Next button
The next step is to select which IDEC HMI is being used. In our example, we are using the HG3G. Select HG3G/HG4G underneath O/I Type and click the Next button
Now we need to specify which communication driver and protocol are being used for communications. In this case, we are communicating via Modbus/TCP. Underneath Manufacturer, select Modicon. Underneath Protocol, select Modbus/TCP Client, since we are setting the HMI up as the Modbus/TCP Master.
As we are only communicating to one Remote I/O module, we can leave the Connection setting as 1:1 Communication. If we were communicating to multiple Remote I/O modules, we would select 1:N Communication. Click the Next button to continue.
