Abstract: An electronic communication system including at least one first communication unit and one second communication unit which are connected to one another by means of at least one first data line. The communication system has a data transmission protocol according to which, in at least one first data transmission mode for synchronized data transmission, the first communication unit transmits a data request signal or a clock signal to the second communication unit via the first data line at least once and the second communication unit transmits a data signal to the first communication unit via the first data line in response to the data request signal or the clock signal.

Abstract: An electronic communication system including at least first and a second communication units (master, slave) which are connected to one another by means of at least one first data line, wherein the communication system has a data transmission protocol which is designed such that at least one defined communication process comprises the transmission of a synchronization packet (frame sync) and/or of an identification packet (ID) and/or a command packet (CMD) and/or of an address packet (ADDR) from the first communication unit (master) to at least the second communication unit (slave) via at least the first data line.

Abstract: A communication system having at least one first and a second communication unit. The first communication unit has a counter memory unit which stores a counter value, and is designed such that the occurrence of a first communication event prompts the counter value in the counter memory unit to be changed in a defined first manner. At least the occurrence of a defined reference event is followed by the counter value in the counter memory unit being changed in a defined second manner. In the course of a second defined communication event, the first communication unit transmits the current counter value in the counter memory unit to the second communication unit.

Abstract: An electronic communication unit which is in the form of a sensor and/or actuator unit, including at least a first status information processing module having a status memory unit which stores status information for the communication unit in the form of a status data item (stat), wherein the first status information processing module further includes a masking memory unit connected to the status memory unit and also a status processing element connected to the masking memory unit, wherein the first status information processing module is designed such that at least one status information item from the status data item (stat) is selected by the masking memory unit and the resultant selective status data item (sel-stat) is processed by the status processing element such that the output of the latter provides a short status data item (k-stat) which has a shorter data word length than the selective status data item (sel-stat).

Abstract: An electric connector with a tolerance compensator, includes a plug-in part and a counter part. An electric connection is established when the plug-in part including at least one electrically conductive pin is plugged into the counter part in the z-direction of a Cartesian coordinate system. The counter part has volume elastic properties, is electrically conductive and forms a predetermined volume. The counter part is limited in the z-direction by, respectively, one contact surface. In order to establish an electric connection, the at least one electrically conductive pin is aligned essentially in the counterpart in the z-direction and traverses a contact surface in an essentially perpendicular manner. The volume area of the counter part is calculated such that the pin reaches the volume allowing a reliable electric connected to be established, in the framework of a permitted path tolerance in the x- and/or y-direction when plugging together.
