FairCom Edge connects to the most common industrial IoT protocols, including MQTT, Modbus, OPC UA, Allen-Bradley EtherNet/IP, and PTC ThingWorx

FairCom Edge connects to the most common Industrial IoT protocols, including MQTT, Modbus, OPC UA, Allen-Bradley EtherNet/IP, and PTC ThingWorx. These connectors enable FairCom Edge to collect tags from various devices, equipment, and manufacturing software.

You can configure these connectors using input actions in the JSON Edge API .


A tag is named data, such as a temperature with a value of 70 . In JSON, a tag is a JSON property, such as "temperature": 70. In a SQL table, a tag is a data field, such as a field named temperature with a value of 70.
