OPC DA client on Pi

Thu Jul 28, 2016 10:49 am

Hello,

I have Loytec L-INX 102 Automation Server with built in OPC XML DA server.
Does anyone have experience with any ready-built libraries i can use?
I need to read/write information from L-INX to RPi and vice versa.

Thank you.

Hi

Did you find any solution? I am also trying to connect to a OPC DA server from Pi3.
How did you solve it.?

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?
