5.12 Operating modes
5.12.1
Overview
The CPU can be in one of 4 operating modes:
n Operating mode ST
OP
n Operating mode START-UP
n Operating mode RUN
n Operating mode HOLD
Certain conditions in the operating modes START-UP and RUN
require a specific reaction from the system program. In this case the
application interface is often provided by a call to an organization
block that was included specifically for this event.
n The application program is not processed.
n If there has been a processing before, the values of counters,
timers, flags and the process image are retained during the transi-
tion to the ST
OP mode.
n Outputs are inhibited, i.e. all digital outputs are disabled.
n RUN-LED off
n STOP-LED on
n During the transition from ST
OP to RUN a call is issued to the
start-up organization block OB 100. The processing time for this
OB is not monitored. The START-UP OB may issue calls to other
blocks.
n All digital outputs are disabled during the START-UP, i.e. outputs
are inhibited.
n RUN-LED
blinks as soon as the OB 100 is operated and for at least 3s, even
if the start-up time is shorter or the CPU gets to STOP due to an
error. This indicates the start-up.
n STOP-LED off
When the CPU has completed the START-UP OB, it assumes the
operating mode RUN.
Operating mode STOP
