For the DNSC port to be a master, the .CO file must use a MAC ID of 00. The Baud Rate must match what is set on the Slave devices. Then .SL file (Scan List) must contain an entry for each Slave device being controlled through the DNSC port. Each entry must be numbered, set to the correct MAC ID for the device, and include the vendor-provided information for Vendor ID, Product Type, Bytes Consumed (Robot outputs), Bytes Produces (Robot Inputs), etc.
Each slave device must have its MAC ID and Baud Rate set, usually this is done by DIP switches on the device. You will need to read the documentation for each device
Thanks a lot, this helped me so much. Today I tried this configuration, I was missing the MAC ID of 00 to identify the channel as a master.
Also the Poll numbers of each device was causing an error, but I read the documentation and now it is working fine.
Thanks again for the answer. Have a nice day.
