“Network detection” service never called.
Network Detection Scenario
First, the Network detection service has to be called. This function will return the number of IO-devi-
ces (NbIOD) detected on the LAN. After, IO-Device Detection service should be called Nb IO Device
times or until the returned status equal to 0. A status 5 is returned when all detected IO-devices ha-
ve already been requested by the service IO-Device Detection
Note: IO-devices are returned in the same order in which they answered to the DCP identify request.
Two consecutive calls to network detection can result in two different lists.
