Installing the 2.0 OPC Service

The OPC Service can be downloaded from the following link:

https://downloads.mvpplant.com/downloads/MVPPlantPLCService_20240705-UA_stable.zip

Please note that the installation of the OPC Service requires the following:

• OPC Server Requirements
• Access to the server where the OPC Service will be installed (normally the OPC server)
  • If the OPC Service will not be installed directly on the OPC Server, the chosen server must be able to communicate with the OPC Server over the network.
• The OPC Service must be able to reach MVP servers.
  • Either the On-Premise servers when using a On Premise implementation of MVP or the cloud at *.mvpplant.com

Configuration Setup

Prior to installation of the service, you will need to edit the OPC service’s configuration file. To begin:

1. Unzip the downloaded file and open the service folder-> Right-click and edit the file “CMMSdg.OPC.PLCSignalRService.exe.config” in a notepad program.

 

2. In the customer node update the following:

• Customer Name: should be the prefix to your mvpplant.com site. Example: if your site name is ‘company1.mvpplant.com’, you would just enter in ‘company1’ as the customer name.
• Username: The Username you use to login to MVP.
• Password: The password you use to login to MVP.
• Remove the comment out characters “!- -“ in the start and end “- -“ of the Customers node line. 

 

3. Only for UA OPC Server clients, will you need to update this section. If you do have a UA OPC server client and are using an ‘Anonymous’ user authentication, then you will not need to update this section either.

• Server URL: OPC Server name/host name
• OPC User: Login name to OPC server client
• Password: Password for client.
• Remove the comment out characters “<!--“ in the start and end “-->“ of the UA Credentials node for each line. 

 

4. App Settings Node:

• Change the value ‘{CUSTOMER_NAME}’ to the prefix you used previously in step 2 for the ‘Auth URL’ key, and ‘URL’ key.
•  OPC Protocol Key: change this to ‘UA’, ‘DA’, ‘UADA’ based off whatever type of OPC server you are connecting to.

5. Client Node:

• Make sure you change the value ‘{CUSTOMER_NAME}’ to the prefix you used previously in step 2 within the endpoint address.

 

Installation

1. To begin the installation process:

• “Run as administrator” the install.cmd file within the root folder.

 

• You should see a successful prompt within CMD and you can also check your services to see “MVP OPC Service” is installed and running. (Make sure that the service is running and is enabled first before any trouble shooting, if necessary).

Adding a Meter Tag

To add an OPC Connector to an MVP Asset meter:

1. Login to MVP One.

2. Select Assets and select the Asset record to edit.

3. Select Edit.

4. On the left-hand side select meter or scroll down to the meter section.

5. Edit the meter by selecting edit. A new meter can also be added by selecting "Add."

6. Select "Attach PLC" once completed.

 

7. Once you enter in your OPC host name, click on the globe icon and it should bring up a list of all OPC servers on the network where the MVP PLC service is installed.

 

8. After you choose the OPC Server within the dropdown, then you will be able to navigate through the OPC server channels to find the tags you would like to add.

Once you have chosen your tag, you will need to enter in the rate you want the service to update the value at. This will be notated in minutes. Click ‘Ok’ once you have finished, and click ‘Save’ on the record to apply all changes.

Certificate Management

MVP OPC Client Certificate:

1. The MVP OPC service tray will be located on your PC’s service tray section with the MVP logo.

 

2. The MVP service tray options will allow quick access to:

• Status of the service (Running or Disabled)
• Management of certificates

 

3. When you try to initially connect your OPC tag within MVP it will show up here as a rejected certificate. Highlight the certificate and click “Trust” to have the certificate trusted by the OPC service.

 

4. It will show up in the trusted section once you have trusted the certificate.

 

OPC Server Client Certificate

When setting up the initial OPC Connector on an Asset, users will need to enter in their OPC Host name in MVP One. Once you select the globe icon, it should find any OPC server on the network the service is on. This is for primary authentication so both OPC server client and MVP Service need to have trusted certificates if you are running UA.

 

Note: Some OPC Server clients will require you to trust the MVP PLC service certificate on UI. If there is trouble connecting to the host, make sure in your respective OPC Server client, that the certificate has been trusted as well.  (Example below is what it looks like in an Ignition OPC Server client).
