Data collecton form shop floor to SAP DMC and vice versa.

Hi,

we are planning to implement SAP Digital manufacturing cloud. I ask , what is the best practice to collect data from (shop floor ) sensors, PLCs, RTUs , etc and send to SAP DMC and vice versa.

Thanks

Hi Hady,

This depends on your exact use case as SAP DM support several different approaches. The documentation can be found HERE .

I general terms you need to install the SAP Production Connector and SAP Cloud Connector on prem and this allows SAP DM to communicate from the cloud to your on prem machines in a secured method.

You then have the option of using an event based approach that can monitor data in real time and then automatically trigger a production process if a set of conditions are met (Manage Automatic Triggers application). You can also use a Pull/Push approach using the Read & Write Indicator services in the Design Production Processes app.

You can also create Setpoints that can be sent directly to the machines as well.

If you can give more details of a use case I can be more specific.

Hope this helps

Kevin

Thanks Kevin ,

About : event based approach that can monitor data in real time and then automatically trigger a production process ,

This will be achieved by OPC UA sever , is it correct? if yes, please tell me the best one to work efficient with SAP .

Hi Hady,

We support several types of servers including OPC UA (we also support IP21, OPC DA, OPC HDA, Asset Framework and Proficy Historian) but OPC UA is a good choice due to its built in security.

As for the choice of the OPC UA server that depends completely on what hardware you are trying to communicate with. Some hardware natively supports OPC UA, others require a 3rd party "translation" tool to convert the actual machines protocol into OPC UA. Examples include Forcam Force Edge, Telit deviceWise, KepServerEX ......... and many more.

Thanks
