Confirm that the Sparkplug Publisher Server Component is Installed

The Sparkplug Publisher extension driver provides the MQTT driver with extra functionality. It provides Geo SCADA Expert with the ability to communicate with MQTT brokers in order to publish data to Sparkplug Host Applications. For such communications, the Sparkplug Publisher component has to be installed on each of the servers on your system (including any permanent standby servers), in addition to the MQTT component.

Use the Add/Remove Programs function in the Windows® Control Panel to check whether the required components are installed.

The Sparkplug Publisher component is located in the Server group, in a branch off from its MQTT ‘parent’ driver component. To check that this component has been installed, ensure that the symbol to the left of the text Sparkplug does not have an X on it.
