I don't know what bechof is. If you don't know what protocol it supports and no-one has already done it then it will be difficult to make progress. Don't they publish the protocols it supports? Modbus or something.

Isn't the CP1L-E an OMRON plc?

One of the protocols most OMRON PLCs use is FINS. A relatively basic UDP / TCP protocol with publicly published documentation that you could use to write a node for node-red.
