Local - Selecting a local connection takes you to a screen that contains a list of the available and running OPC servers located on the local machine. There are only a couple of differences for a remote connection that will be highlighted along the way. For the most part, setting up a local or remote connection to an OPC-DA server is the same. Choose the OPC-DA COM Connection and then s elect whether you want to make a Localconnection or if the OPC server resides on a Remote machine.Go to OPC Connections > Servers and then select Create new OPC Server Connection.

Due to the complications that Windows DCOM security settings can cause, this set-up guide is followed by the Troubleshooting OPC-COM Connections section that deals with an overview of how to deal with a faulted server connection due to DCOM security settings as well as other possibilities. This section provides a brief walk-through of how to set-up a new Local or Remote OPC-DA server connection using the COM module. All subscriptions to the server will use the same connection. Connections to OPC servers will be held open while the Ignition Gateway is running. If you have an OPC server that is not capable of accepting OPC UA connections and you need to talk to a PLC for which Ignition has no supported driver, you'll have to use the OPC-COM module to make your device data available in Ignition. The OPC-COM module provides the ability to connect to OPC servers that only communicate using the older COM based OPC-DA standard. For other operating systems, OPC UA must be used. Therefore, the information in this section only applies to Ignition Gateways installed on Windows. Note: Classic OPC is based on COM, which is a technology in Microsoft Windows.
