Abstract: A diagnostic apparatus (101) for diagnosing faults within a lighting system comprising at least one luminaire (121), and at least one presence sensor (123, 151) configured to control the operation of at least one luminaire (121) when an object is within the presence sensor (123, 151) sensing range, the diagnostic apparatus (101) comprising: a user input (103) configured to receive at least one input to control the at least one luminaire (121); and a fault determiner (221) configured to determine at least one lighting system fault based on the at least one input and wherein an object is within the sensing range of a presence sensor (123, 151) expected to be associated with the at least one luminaire (121); and a fault reporter (223) configured to generate at least one fault report based on the determined at least one lighting system fault.

Abstract: A lighting-control processor (100, 300) for controlling operation of an external lighting unit comprises an exchange control unit, which is configured to control exchange of lighting-control information with the lighting unit via a lighting-control interface in accordance with an exchange protocol and to generate and provide exchange monitoring information indicative of an operational status of the exchange control unit. A reset unit is configured to receive a soft-reset command and to cause a soft reset of the lighting-control processor upon receiving the soft-reset command. An exchange watchdog unit is configured to receive the exchange monitoring information, determine validity of the exchange monitoring information in accordance with a predefined validity criterion, and to provide the soft-reset command upon detecting that the received exchange monitoring information is not valid.

Abstract: A lighting system (100) for illuminating an environment and a method of starting the installation of a program on a programmable controller of a lighting module are provided. The lighting system (100) comprises a particular lighting module (110), a neighboring lighting module (120) and an installation decision generator (112). A portion of the environment is illuminated by both lighting modules (110, 120). Both lighting modules (110, 120) have a programmable controller (114, 124) and may receive a program via a network interface for installation on the programmable controller (114, 124). The installation decision generator (112) decides whether the installation of the program on the particular lighting module (110) may start, based on operational information as to whether the light emission capabilities of the neighboring lighting module (120) enable illumination of the portion of the environment to be sufficiently close to a desired illumination of the portion.
