Operating behavior
8.1
Failure of supply voltage
In case of a complete power supply failure a Reset is triggered. All lined-up
modules are also set into reset-status and all outputs are switched off.
Data in the battery-buffered SRAM remain intact and the real-time clock con-
tinues to run.
8.2
Response to module errors
In case an error occurs, this error will be displayed on the diagnosis display on
the front side of the CP 263/x.
Further information: See system manual.
8.3
Watchdog
●
The CPU watchdog runs independent from the IO watchdog. After the CPU
watchdog responds, all data will be saved, all device outputs switched off
and then the device is reset.
●
The K-Bus watchdog causes a K-Bus reset and the outputs of the K-Bus
module will be disabled.
