CIMHT_004 How to Configure the CIMPLICITY HMI OPC Server GE
How to Configure the CIMPLICITY HMI OPC Server
The GE HMI/SCADA – CIMPLICITY product has a built in OPC Compliant Server that is capable of
publishing CIMPLICITY point data to an OPC Client. This document is intended to demonstrate how to
configure the CIMPLICITY OPC Server so that successful communications can be obtained. This
document is directed towards CIMPLICITY 7.0 but is valid for versions 4.0 or higher.

How it works
When a CIMPLICITY project is running it is generally updating point data with values as conditions
change in the devices/servers that it is talking to. This data can then be fed up to the CIMPLICITY OPC
Server via a Point Management interface that allows the OPC Server to receive these value updates,
This then allows the OPC Server to propagate the updates to interested OPC Client(s).

Step 1: Verify the CIMPLICITY Project is Running
The first step in the configuration is to make sure that your CIMPLICITY project is currently running. This
should be evident by going into CIMPLICITY Options via the Windows Start menu and see if your project
is listed in the running projects list on the Projects tab.
Figure 2 – CIMPLICITY Options showing the Running Project.
Step 2: Setup the OPC Server Security
After confirming that the project is running, the CIMPLICITY OPC Server must be manually launched in
order to configure the security permissions on it. The CIMPLICITY OPC Server can be started by going to
Start->Programs->Proficy HMI/SCADA – CIMPLICITY->OPC Server.
Note: The OPC Server only has to be started in order to configure it. When an OPC client connects to
the OPC Server then it will automatically launch the OPC Server.

Once the CIMPLICITY OPC Server is open then go to Edit->”Server Configuration….”. A new dialog will be
displayed titled “OPC Server Configuration”.
Figure 4 – The OPC Server Configuration dialog prior to configuring a project connection.
Click on the “Add” button along the right hand side of the dialog. A new dialog will appear called
“Project Properties”. In this dialog choose the project from the dropdown and put in the CIMPLICITY
username and password to be used for the OPC Server. Typically this is a highly privileged user who
has access to all of the points in the project (i.e. Administrator).

When complete, click on the “OK” button to close the dialog. On the Server Configuration Dialog
highlight the entry that you just added and click on the “Show this Name Space” button. This will allow
the OPC Client applications to browse the OPC Server. In addition, make sure there is a check in the
box that says to “Reconcile Cache…”. This tells the OPC Server to make sure it stays up to date when
the Project is stopped and started. When all of these configuration steps are complete, it should look
as follows.

You can now click “OK”.
In the main CIMPLICITY OPC Server application window, it should show a green dot next to the project
name in the list. This indicates that it has successfully connected to the project and retrieved the latest
point list.

Now close the CIMPLICITY OPC Server. At this point it is ready to accept connections from OPC Clients.
Step 3: Connect an OPC Client to the OPC Server
Connect up with your preferred OPC Client application. The CIMPLICITY OPC Server should launch, and
the OPC Client should now be able to browse the points on the project that you have configured in the
