Microsoft, OPC Foundation and Moxa cooperate

Moxa, Microsoft and the OPC Foundation are cooperating on IoT and are presenting their first result: an industrial gateway with an integrated OPC UA Publisher module, which will soon be available in a starter kit.

By using Windows 10 IoT and an OPC UA Publisher module, the 'MC-1121' gateway offers a way to securely and reliably transfer data from field devices to the cloud.

Moxa has worked closely with the OPC Foundation and Microsoft to adopt the functionality of OPC UA. Among other things, Moxa hardware is used for testing Windows 10 in the IoT. Moxa's MC-1121 series of IIoT gateways are used. These transfer device data to the cloud and support the OPC UA Publisher module, which enables data to be transferred to the Azure IoT Hub. According to Moxa, the gateways have a variety of interfaces to connect Ethernet, serial and I/O devices and can be used together with 'Microsoft Connected Device Studio'. This should make them an all-in-one solution for small to medium-sized installations or for easily connecting large-scale installations to the cloud. In addition, a starter kit has been put together as a collaboration project between Moxa, Microsoft and the OPC Foundation, consisting of the MC-1121 gateway with Windows 10 IoT and the OPC UA Publisher, which will be available from the first quarter of 2018.

"By utilizing OPC UA technology, Moxa gateways address the integration of information between control systems," says Thomas J Burke, President of the OPC Foundation.

Moxa intends to show the results of the collaboration with a live demonstration at this year's IoT Expo in Taipei. An application will show how easy it is to collect data from various devices and sensors, such as temperature sensors or coolant sensors, as well as other signals and then send them to the Microsoft Azure Cloud using the OPC UA Publisher module in Windows 10 IoT.

Scalable solution required

OPC UA has long been used as a method to connect the OT and IT worlds. It is important for the Industrial Internet of Things (IIoT), where many devices and systems using different protocols need to communicate with each other. Originally, OPC UA worked on a client-server model. However, when hundreds or thousands of devices need to be connected across multiple locations, a scalable solution is required. This led the Foundation to look at a publisher-subscriber model that offers optimized communication with greater scalability and resilience.
