I have a old Knauer Simulated moving bed chromatography system (model: 2003). Unfortunately the system was not in use for many years. Now I want to make this system functional. I have checked all the hardware components and all of them are working fine, however I am unable to establish the communication between Valvechrom (software) and hardware component. Your valuable suggestions on setting up SMB configuration in Valvechrom will be really useful to me.
