CP-Link 3 Service

The CP-Link 3 Service provides an ADS interface for setting the HID-Focus manually (also see Set the HID focus manually). Starting with CP-Link 3 Version 1.3.xx the CP-Link 3 Service is implemented as TwinCAT Server, in earlier versions as Windows Service application.

CP-Link 3 Service as TwinCAT Server (Starting with CP-Link 3 Version 1.3.xx)

▪: If you install CP-Link 3 on a PC with an already installed TwinCAT, the CP-Link 3 Service is registered as TwinCAT Server during the installation automatically.

▪: If you however install TwinCAT on a PC with an already installed CP-Link 3, you need to register the CP-Link 3 Service as TwinCAT Server manually.

If you install TwinCAT on a PC with an already installed CP-Link 3, the CP-Link 3 Service has to be registered as TwinCAT Server subsequently. This requires the TwinCAT System to be stopped. Open a command-line window and navigate to the subfolder Services in the CP-Link 3 program directory, e.g. "C:\Program Files\Beckhoff\CP-Link 3\Services". Now type "CPLink3Service.exe /RegTcServer" into the command-line to register the CP-Link 3 Service as TwinCAT Server. A window is displayed giving status information about the registration result.

You can use the TwinCAT Storage Editor to verify that the CP-Link 3 Service is registered as TwinCAT Server.

CP-Link 3 Service as Windows Service application (up to CP-Link 3 Version 1.2.xx)

During the installation of CP-Link 3 the CP-Link 3 Service is registered and started as Windows Service application automatically.

Verify status, modify properties

A list to manage Windows Service applications can be opened via the start menu Start -> Control Panel -> Administrative Tools -> Services. The status of the CP-Link 3 Service should be "Started" and the startup type should be "Automatic". If not, configure the service according to the mentioned criteria. In case the CP-Link 3 Service is not in the list of services, it has to be registered as Windows Service application manually. Open a command-line window and navigate to the subfolder Services in the CP-Link 3 program directory, e.g. C:\Program Files\Beckhoff\CP-Link 3\Services". Now type "CPLink3Service.exe /RegServer" and then "CPLink3Service.exe /service" into the command-line. Refresh the view of the services window. The CP-Link 3 Service should be in the list of services now. Maybe you need to modify the properties of the service to match the criteria mentioned above.
