Integrate tags from Schneider Unity Modbus

This task describes how to add a Schneider Modicon M340 PAC or Modicon Premium PAC as a tag integration source in your IWS project.

This tag integration is based on the SCHNE driver, which communicates with Schneider Modicon devices using the Modbus protocol over Ethernet.

Before you begin this task, you should do the following:
  • Review the manufacturer’s documentation for your Schneider Modicon device and the Schneider Unity Pro software;
  • Use the Schneider Unity Pro software to export an I/O configuration file (*.XSY) from your PLC program;
  • Read the SCHNE driver documentation (on the Help tab of the ribbon, in the Documentation group, click Communication Drivers, and then select SCHNE); and
  • Make sure the source device is running and available on your network, and note its network address.

To add a Schneider Modicon device as a tag integration source:

  1. On the Project tab of the ribbon, in the Settings group, click Communication. The Project Settings dialog is displayed, with the Communication tab selected.
