I’m a beginner, maybe this is a stupid question, but: when I connect to my installation with an existing program, I get errors: red cross on each device. So each time I create “new program” and read all devices before going on with programming. How can I connect to my installation with the existing program?
We have a programming guide for beginners available on our website: https://www.velleman.eu/downloads/velbus/00_general/guide_velbus_02_configuration_en.pdf
Basicly, you should scan the installation when you are connected and make sure you read out the configuration from the modules unless you’re sure that the existing program has an up to date configuration.
