No sure, but maybe “process orchestration layer” in the context of MTP, the “module type package” … related to standards in process industries if I’m not mistaken.
POL is known in the plants as process control systems , in Siemens we have PCS 7 and PC7 neo and our Scadas built in Wincc Unified for example. Other process control systems come from other process vendor….
The idea behind machine proxy is created a abastraction layer to integrate the bown field to MTP standards ( NAMUR 2658), the edge device+ machine proxy get data from the brown field with his comm connectors and map the variables to the standard, in order to use the machine with a plant that adopted MTP.
For the greenfield we have a PLC s7 library, to do native our PLC with the MTP standard..
So Could you use edge to built a POL, of course, you have hardware / software to build any app, indeed in node red you can build and web SCADA...but it is no the idea behind machine proxy, It has no sense to implement a PCS S7 process control system in the industrial edge enviroment.
Hello Caleb,
there is already a Machine Proxy – Module Type Package – Application available in the Industrial Edge Marketplace ==> https://www.dex.siemens.com/edge/manufacturing-process-industries/machine-proxy?cclcl=de_DE
Is this what you are looking for?
