Connect SIEMENS SIMATIC ET 200SP to Azure IOT

Question

We are working on prospect and pushing Microsoft Azure IOT solutions to implement Industry 4.0 for Manufacturing Industry.
We demoed Azure IOT capabilities and customer is very excited and want to proceed further.

Customer are using SIEMENS SIMATIC ET 200SP, PLC and already collecting data from sensors.
As part of Phase 1, we want to develop Azure IOT Edge which will talk to SIMATIC ET 200SP and collects/upload data to IOT Hub.

We need some help/guidance especially on how to connect SIEMENS SIMATIC ET 200SP and if their is already certified Azure Device that can be used.

Hello @Nagaraj Jadhav ,

The options to connect the SIMATIC ET 200SP depend on its configuration. The product page lists interface modules for PROFINET and PROFIBUS as well as an Interface MultiFieldbus modules to PROFINET, Ethernet IP and Modbus TCP.
Additionally, one might not connect directly to the SIMATIC ET 200 SP on the shop floor and instead connect to an attached PLC (e.g., SIMATIC S7-1500) in the control room / cabinet. If there is a PLC and it is providing an OPC UA Server, you can use the OPC Publisher module to connect IoT Edge with the PLC and obtain the data from the SIMATIC ET 200SP and other data sources.

Alternatively, one could a middleware like Kepware KEPServer, Softing dataFEED, Matricon, Ignition or others to handle the lower level protocols and providing an OPC UA server for accessing it from IoT Edge, here is an link to an example for KepWare
