Delta RMC151 - Manual (Page 1033)

9 Register Reference
RUN Mode (98) command is
issued. It will also be set
immediately if the controller
is set up to start in RUN
mode.
2 _Controller.Status.FirstScan First Scan
Goes high (1) on first scan
after entering RUN mode,
otherwise it is low (0). See
the Program Triggers topic for
usage details.
The system tag _FirstScan is
identical to using
_Controller.FirstScan.
3 _Controller.Status.WDReset Restart due to Watchdog
Timeout
If the last controller startup
was the result of a watchdog
timeout causing the RMC to
restart, this bit will be set
until the RMC is powered off.
A watchdog timeout is
typically caused by a bug in
the firmware. If the RMC did
not restart due to a watchdog
timeout or unhandled
exception, then it was
because of a power problem.
After any restart caused by a
watchdog timeout, the RMC
CPU LED will alternately flash
red and green for 10 seconds.
Requires firmware 3.42.0 or
newer and compatible loader.
4 Restart due to Unhandled
Exception
If the last controller startup
was the result of an
unhandled exception causing
the RMC to restart, this bit
will be set until the RMC is
powered off.
After any restart caused by an
unhandled exception, the RMC
CPU LED will alternately flash
red and green for 10 seconds.
Requires firmware 3.42.0 or
newer and compatible loader.
