References81[132] Presence Sensor Warning: both the presence sensors remain closed for morethan the programmed No Phase timeout. This message may indicate that no pack ispresent on the conveyor. Furthermore, it is assumed that both presence sensorsare correctly synchronized otherwise a [131] or [133] error would be generated.[133] PS Output Failure: the PS Input is active while the PS Output is inactive. When noinformation about movement is provided, it is assumed that the broken presencesensor is the one which does not signal the packs entering the tracking area. Thecorrect synchronization of the two presence sensors is periodically checked bycounting the number of their status changes within a sampling period of 4 minutes.[149] Not availableSerial On Line ModeDiagnosticsError NumberMeaning[132] Presence Sensor Warning: there is no Reading Phase for more than theprogrammed No Phase timeout.

Inthis way the Slave scanners act as Stand Alone Devices which can send their data not only to theirconfigured communication channels but also to the Master. The Master can be configured to sendthis data as a complete message to its configured communication channels with header, addressand separators (see Multidata).Topology RoleDefines the scanner topology role:Master SYNCHRONIZED: The scanner is connected as an ID-NET™ Master in a master/slave synchronizedconfiguration.Slave SYNCHRONIZED: The scanner is connected as an ID-NET™ Salve in a master/slave synchronized configuration.Master MULTIDATA: The scanner is connected as an ID-NET™ Master in a master/slave multidata configuration.Slave MULTIDATA: The scanner is connected as an ID-NET™ Salve in a master/slave multidata configuration.Other: This selection allows Local Device Alternative Network Settings to support (Master/SlaveRS232 networks or Stand Alone applications.
