The XML Service writes a value of 1 to Connection Handshake in the ServiceData table in the LAP Database every second. The PLC Service reads the Connection Handshake value and if that value is 1 it writes a 0. If the value is still a 1 it starts a timer that runs for 10 seconds. If the value does not change to 0 within the 10 seconds a value of -2 will be written the LifeCounterIN tag in the PLC, otherwise it writes a 1 to the LifeCounterIN tag in the PLC.
