Dear Expert,

I do configure one project with profinet IO to test one machine. then I need the same software to test one section of machine where some IO station is not exist. (all IO are in Topology configure with isochronous mode)

I see possibility as below.

existing node might not able to run because previous station is not existing. Here I could delete all missing module out in hardware configure but then I would get compile error because of missing IO.

any solution on this ?

any other suggestion ?

I think you may using the function _deactivateDpSlave / _activateDpSlave for the slave missing. Also you can take a look in the installation DVD the chapter "modular machine"
