Abstract: The invention provides a computer implemented method for test of a control system for a logistics system. The method comprises testing (TST1, TST2) one or more low level control (LLC) software parts by simultaneously emulating a high level (HLE) response, emulating a low level emulating (LLE) response, and interfacing (INF) said HLE and low level emulation LLE. The interfacing (INF) of the HLE and LLE, comprises two-way exchanging a plurality of parameters (P) indicative of items to be handled in the logistics system between the HLE and the LLE. With such interfacing of a HLE for testing of a high level control (HLC) software of the logistics system, and the LLE for, it is possible to provide a realistic test and tuning of LLC software parts, e.g. Programmable Logic Controllers (PLCs) code, before the physical elements of a complex logistics system is built, e.g. an airport baggage handling system.

Abstract: A device and method for performing page scan on a first communication channel by listening to the first communication channel, which includes set-up parts for performing a page scan on the first communication channel, a first timer for defining a first time interval between successive page scans, a second timer for defining a second time interval between successive page scans, where the second interval is shorter than the first interval, wherein the set-up parts are responsive to second channel communication parts and are adapted to use the second timer when a connection on the second channel is being initiated in the device, and to use the first timer when the connection on the second communication channel has been initiated.
