Standard protocol for a LED Display Panel


Thread Starter


Hello, List:

I'm interested in interfacing LED displays with a PLC via a Standard Protocol like Modbus, MB+, Modbus ASCII or something like this to show data
or to generate messages in a packaging production line.

Does anyone know about somebody that produces or sells this kind of displays?

I was also looking for a led display to generate information on a display. I used a LAUER display. Those displays are capable to use different protocols.
