I want active them one by one to communication with device via multi VISA RS232 BUSes, I use "Periodic - I/O Server" act as "On Input Change - I/O Server" because all "On Input Change - I/O Server" run one by one within the SVE, once a server is waiting for respond, no others can run. I want my "Periodic - I/O Server" deactive itself when it finish one cycle.
