)
Parameters
Notes
The instruction only be used in section
INIT
:
, since it takes long pro-
cessing time.
As long as the watchdog counter is enabled, it decrements the counter
value continuously. After the set release time the counter value reaches
0 (zero). If so, the module assumes a malfunction and stops; thus, all
output signals are reset.
After power-up of the module the counter is set to the start value 10ms
and the watchdog counter is enabled.
Reset the active watchdog timer at least once to the start value within
the counting interval, in order to keep the module working. To reset the
module use any module specific instruction or
LS_WATCHDOG_RESET
.
The watchdog function is used as to monitor the connection between
ADwin
system and LS bus module.
