Try testing the S7 1200 for PTO as per your control and the physically connect the DO to the drive inputs ...it will work for sure.

So, the application I sent you is really good to get a first overview. Try to configure your system step by step with the help of the application. If you stop in one point and can't get on because of understanding-problems, feel free to ask again detailed question. But its difficult for the people here to answer your question in detail without knowing the problem in detail. Here maybe a small guidline: 1. Read the application and try to understand 2. Figure out your drive parameters which are needed for this, what you want to do 3. Try to setup the PLC with the drive parameters 4. Try to control your drive by PLC 5. Figure out the problems you do have by doing this. Hope this helps a little bit in the right direction. regards

Whereas a servo drive will usually have a PTO. So which drive are you having and which mode you need to connect?
