Description

The Data Logging Unit BDB/S 1.1 is a modular installation device for fast installation in the distribution board with a module width of 2 space units.

The Data Logging Unit enables you to count the switching  operations of switch actuator channels in a KNX system. Furthermore, the operating hours of the connected loads can be recorded with a resolution of up to one second. 35 independent channels are available each with seven communication objects provided. The switching operations as well as the operating hours can be recorded on a channel basis, where the counting method from zero upwards or from a set value downwards can be selected. The operating data of every channel is derived from the state of the communication object Channel X switch position - received.

Via a communication object or parameter it is possible to define the corresponding start or limit value for each individual switch operation counter value. With a total value mode of counting, i.e. counting from zero up to a set limit value, an alarm message is generated if the limit value is exceeded. With a remaining value mode of counting, i.e. counting from an adjustable start value down to zero, an alarm message is generated if zero is reached.

Via a communication object or parameter it is possible to define the corresponding start or limit value for each individual operating hours counter value. With a total run time mode of counting, i.e. counting from zero up to set limit value, an alarm message is generated if the limit value is exceeded. With a remaining run time mode of counting, i.e. counting from adjustable start value down to zero, an alarm message is generated if the zero is reached.

The counter values and start or limit values can be changed via the bus. The values can only be modified after enabling via a communication object. Via the communications object Delete all operating data - System all operating data can be deleted in the Data Logging Unit. 

Every state change adjustable via parameters increments the current counter value of the operations counter by one. The level to count the operating hours can be defined via a parameter. The Data Logging Unit can even be set to count permanently via the level setting. Counting is undertaken every second.

During a new start the switching states of the monitored switch actuator channels are read after a settable time. A pause can be programmed between the two corresponding telegrams. If a switch actuator channel does not respond, the telegram will be repeated twice. On bus voltage failure all counter values and start or limit values are saved in the BDB/S 1.1 and restored when the bus voltage recovers. If the limit values are exceeded, the Data Logging Unit sends the respective alarm messages on the KNX Bus.
