Parameterization and Commissioning
K-Bus Re-Trigger
If the processor is busy dealing with the PLC project or the SSB, the K-Bus cannot be processed for a
certain amount of time. This leads to triggering of the Bus Terminal watchdog and dropping of the outputs.
The Bus Terminal Controller is set such that the K-bus watchdog is re-triggered 3 times after 85 ms. The K-
Bus watchdog would then be activated.
K-Bus Re-Trigger 0: 100 ms
K-Bus Re-Trigger 1: 2 x 85 ms = 170 ms
K-Bus Re-Trigger 2: 3 x 85 ms = 255 ms
K-Bus Re-Trigger 3: 4 x 85 ms = 340 ms
Reaction on K-Bus Error
In the event of a K-Bus error, the K-Bus inputs are set to "0" or retain their last state.
Response on PLC-Stop
The user can set the behavior of the fieldbus output data in the event of the PLC project being stopped. The
master will use these data as input data. In the event of a PLC stop, the data can be set to "0" or remain
unchanged.
