Sorry, I didn't describe it clearly, and thank you for your answer. these motion axes are controlled via softmotion. I don't have customer's programs here, so I drew a diagram to show the actual situation. In the picture, they configured a fixed number of slaves (four drives) in the PLC project to run the program. But in reality, there are two different configurations of slaves in the control network, and it is necessary to switch from one slave to another at different stages during the program running. (For example, from 4 to 3 drives). These two phases have the same control program, just using different number of drives. So in this case one drive must be automatically disabled by the program, otherwise the communication will be wrong. Is there any way to solve this problem without having to disable the drive offline by hand?
