Setting up Device Communication

The OFSOPC driver handles device communication through the integration of OPC Factory Server (OFS) on the I/O Server. Individual devices are addressed through the use of OFS alias names in the configuration of your Plant SCADA variable tags.

Setting up communication within a Plant SCADA project is therefore a straightforward process of connecting to OFS locally on each I/O server.

See Communication Settings for the default settings used by the Express Communication Wizard when configuring the connection to OFS as a device.

Note: If you want to use the OFSOPC driver on an I/O server that is running as a Windows® service, you need to make some additional configuration settings on the I/O server.
