I'm having the same troubles with a Loytec L-VIS 3ME7, till now i succesfully used opc-ua and bacnet ip from Node-red to the L-VIS screen and from Codesys for Raspberry Pi with Modbus TCP/IP
But this solutions do not work in the way you could with OPC XML/DA.
With Bacnet i can read and write datapoints to Loytec with their Bacnet numbers. Until now the reading and writing looks to be stable.
With OPC-UA you can calculate a number from the datapoint UID and read, write of subscribe a point, but in Node-red it was not stable, and didn't restart the connection when an error occured.
Both working from node red, to the Loytec device and not as a slave device.
Do you guys have figured out some other (maybe also more stable) solutions?
