Read Beckhoff PLC data with Arduino

Projects General Guidance
1

Hello,

I am wondering how I can read data from a Beckhoff PLC in order to control a DC motor.
I ordered an Ethernet shield and an RS232 one.
Should I connect the arduino to the network and to route data with Kepware?
Do you know if its possible to directly link the PLC with the Arduino?
Is it there a way for arduino to access a database and read this data?

I am very lost on this,

Thank you for your guidance

It depends on the PLC, if it is transmitting the wanted data somewhere. Then You need to know the syntax, the formatting of the data.

what i know is that there is a kepware taking the data and publishing to a server, however I am wondering if the PLC itself can send the data without kepware

Reading users manual is my suggestion.
