OPC UA is the most common interface to communicate with machines and PLC's.
With Siemens and Beckhoff PLCs we communicate directly via OPCUA.
For all other PLCs we work with KepWare Ex.
This protocol enables us to allow ERP software to communicate with machine data.
Order data such as recipes, quantities, targets, setup information and others can be sent directly to the SCADA software on the machine.
We register the recording of start and stop times, standstills and error messages in our OEE software that calculates the online efficiency parameter.
