System stop

The bus coupler's "system stop" mode is indicated when the DIA
LED (see Tab. 19 on page 89) is flashing.
If the system is stopped, the outputs return to a safe mode (=
"0") and the bus traffic to the INTERBUS S master is interrupted.
The system stop mode can only be exited by restarting the
assembly (power on).
If the system stop is activated, this is because of a one-time
error caused by the hardware or firmware.
When starting the bus coupler (power on), the hardware
components are tested. If an error is found, the system is then
set to the "system stop" mode.
Plausibility tests are constantly carried out while the firmware
is running. If an error is detected during these tests, the "system
stop" mode is activated.
