The first version was based on programming an application. The new version is based on docker images, each being a separate application, which has to be stored in the container registry of your choice (like Docker Hub or your own container registry in Azure.

One of these modules is a Modbus module. It’s available at the Docker Hub of Microsoft. Modbus is a great protocol for highspeed communication over TCP and I have already blogged about it, using the previous IoTEdge SDK version.

Let’s check out how we get some telemetry from it.
