I am looking for some suggestions for setting up a I/O module. I am working with a Vkrc2 control cabinet that doesnt have any I/O ports only the option of using devicenet or interbus. Because of Vkrc cabinet there also isn't the option to switch to automatic mode, only to automatic external. If i am correct i need a minimal of 4 input signals to start an automatic program. 1. clear error messages 2. drive enable 3. start program and 4. allow movement. some extra in and outputs could also be useful but isn't a priority right now.
I don't have much experience in using device net or interbus so i would like to know what you suggest. what kind of I/O module, using devicenet or interbus. any help you can give is much appreciated.
small note: I am working with a Vkrc cabinet but the software is the standard software for the krc2
