Monitoring concept
19973
The controller monitors the supply voltages and the system error flags.
Depending on the status...
• the controller switches off completely
> the program stops
> the outputs become currentless and change to logic "0"
> the status LED goes out
>
Monitoring and securing mechanisms
After application of the supply voltage................................................................................................. 15
If runtime system / application is running ............................................................................................ 16
If the TEST pin is not active ................................................................................................................ 16
One-time mechanisms ........................................................................................................................ 16

For the these devices the following monitoring activities are automatically carried out:
>
After application of the supply voltage
3927
After application of the supply voltage (controller is in the boot loader) the following tests are carried
out in the device:
>
RAM test (one-time)
>
supply voltage
>
system data consistency
>
CRC of the boot loader
>
if exists and is started: CRC of the runtime system
>
if exists and is started: CRC of the application program
>
memory error:
• If the test is running: flag ERROR_MEMORY = TRUE
(can be evaluated as from the first cycle).
• If the test is not running: red LED is lit.
