OPC Server
From SysCAD Documentation
Navigation: User Guide -> Data Sharing -> OPC Server
The SysCAD OPC Server can be used for a number of applications, including operator training. The OPC Server can be used to connect to software (eg operator interface software) or hardware (eg PLC). All you need is an appropriate OPC Client driver for the hardware or software.
To use the OPC Server functionality in SysCAD you will need to have purchased the OPC Server add-on, otherwise the licensing will disable these features.
The steps involved in using OPC Server in a SysCAD project are:
- Set up a SysCAD dynamic project.
- Switch on the OPC Server option. See Project Project Settings IO Connection Tab page.
- In the OPC Client connect to the SysCAD OPC server.
- Enter any valid SysCAD tags in the OPC Client that you wish to subscribe to.
There are various free OPC Client test tools that can be downloaded and used to test SysCAD tag connectivity to the SysCAD OPC Server.
For OPC connection over a network, you need to ensure on the client and server ends all the appropriate DCOM permissions are configured correctly.
OPC Server Options
The OPC Options dialog box is to keep the user informed of the communication status between SysCAD and the OPC Client. When SysCAD is running and communication established, the statistics page will list a summary of the communication between the packages:
and the tags page will list all the tags and their values passed through by OPC.
The Refresh button refreshes the dialog box and the Force All button will force communication to take place regardless of value change. The Options button will open up the following dialog box allowing the user to set some extra options.
