Troubleshooting Connection Lost

By default, OPC group of items and OPC field data points do not provide any indication if the connection between Desigo CC and any third-party OPC server is lost or not established.

To be notified of this issue you must set the config file so that #COM will be displayed for the third-party OPC client points properties. Do the following:

  1. Navigate to GMSProjects > [project] > config.
  1. Open the config file with a text editor.
  1. Locate the OPC server and specify the following:
    [opc_[OPC server name]]
    setInvalidForConnLoss = 1
Example of configuration
  1. Repeat the previous step for each OPC server.
  1. Stop and restart the OPC drivers connected to the OPC server. See Starting or Stopping the OPC Driver.
