Using Hilscher's netIOT Edge Gateways helps avoiding this effort. netIOT Edge Gateways allow process values to be recorded by passive 'listening' on the automation network and making that data available to the IoT application. The tapping is carried out without any influence to the network, so that existing systems can be made IoT capable within minutes without any further modifications. In addition, passive access to the field data ensures that no disturbances from the IT network can occur in the OT network, be they unintentionally or intentionally caused.
Commissioning of the netIOT Edge Gateway is simple. In a short production pause, the network connection between the PLC and the field devices are briefly disconnected. At this point, the netIOT Edge Gateway is installed using a network TAP. Once the network cables have been plugged in again, production can continue straight away. The netIOT Edge Gateway can now be further parameterized without affecting the running production and the connection to the IoT application can be realized. Process values from the field are available through the netIOT Edge Gateway via OPC UA or Node-RED.
