Abstract: The disclosure relates to a door control system (100) for remote operation of a door (1) by a user (20), the system (100) comprises a door operator terminal (10) configured to be operated by the user (20), a door operator control unit (30) configured to control operation of a door (1), a processing circuitry (102a, 102b, 102c) operatively connected to the door operator terminal (10) and the door operator control unit (30) configured to send, from the door operator terminal (10), a command message (CM) indicative of an instruction to the door operator control unit (30), receive, at the door operator terminal (10), a command response message (CRM) comprising a determined instruction from the door operator control unit (30) and determine if the determined instruction comprised in the command response message (CRM) corresponds to the instruction in the command message (CM) previously sent by the door operator terminal (10).

Abstract: An error data reporting arrangement (20) is disclosed which is for use in an entrance system (10) having one or more movable door members (DM1 . . . DMn) and an automatic door operator (30) for causing movement of the one or more movable door members (DM1 . . . DMn) between closed and open positions. The error data reporting arrangement 20 comprises a controller (22), a memory (24) and a communication interface (26). The controller (22) is configured for repeatedly collecting event data in the entrance system (10), and for maintaining a set of recent event data in the memory (24) while discarding older event data. The controller (22) is moreover configured for detecting an error condition in the entrance system (10), and, upon detecting the error condition, for generating an error report (27) which comprises information representing the error condition together with information representing the maintained set of recent event data.

Abstract: The present invention relates to a door operator (1) and to a method performed in a door operator system (100) comprising a door operator (1) connected to and arranged to move at least one door leaf (5) between an open and closed position, the door operator (1) comprising a control unit (3) configured to control the movement of the at least one door leaf (5), the method comprising: obtaining (S100), in a sleep mode of the door operator system (100), a sequence of input data in one or more components of the door operator (1) or the at least one door leaf (5), receiving (S110), in the control unit (3) of the door operator (1), said sequence of input data from the one or more components, and evaluating (S120) said sequence of input data and ranking (S130) the probability of that said sequence of input data corresponds to an intrusion attempt on the door operator system (100).
