“Watchdog” functions; monitoring of the serial data flow
If, once this function has been activated (see NAMUR commands),
there is no retransmission of the command from the computer
within the set time (“watchdog time”), the Evacuation function is
switched off in accordance with the set “watchdog” mode or is
returned to previously set target values. The data transmission may
be interrupted by, for example, a crash in the operating system,
a power failure in the PC or an issue with the connection cable
between the computer and the device.
“Watchdog” mode 1
If event WD1 should occur, the evacuation function is switched
off and WD1 Watchdog Error is displayed. Set watchdog time to
m (20 - 1,500) seconds, with watchdog time echo. This command
launches the watchdog function and must be transmitted within
the set watchdog time.
“Watchdog” mode 2
If there is an interruption in data communications (longer than the
set watchdog time), the speed target value is changed to the set
WD safety speed limit. The warning PC 2 is displayed. The WD2
event can be reset with OUT_WD2@0 - this also stops the watch-
dog function.
Set watchdog time to m (20 - 1,500) seconds, with watchdog time
echo. This command launches the watchdog function and must
be transmitted within the set watchdog time.
