AC500-S Safety Modules
SM560-S Safety CPU > SM560-S module states
All CoDeSys online services from "Online" menu are available for users, but only three of them can be exe-
cuted without leaving RUN state: "Login", "Logout" and "Check boot project in PLC". All other services (e.g.,
set a breackpoint) switch SM560-S to DEBUG states (DEBUG RUN or DEBUG STOP).
SAFE STOP
SM560-S goes to SAFE STOP state if fatal/serious errors were identified. All PROFIsafe output telegrams
are nulled (no valid PROFIsafe telegrams are generated in this state). No CoDeSys online services from
"Online" menu are available for users.
This state can be left only using powering off/on or "reboot" PLC Browser command on PM5xx Non-safety
CPU.
DEBUG RUN
DEBUG RUN state can be reached if CoDeSys online services from "Online" menu are used (except
"Login" , "Logout" and "Check boot project in PLC" ) from safe RUN state. The user can set a breakpoint in
the safety program, perform "Single cycle" program execution, force and write variable values and execute
other debugging functions of CoDeSys Safety.
If CoDeSys online service "Stop" is called or the breakpoint is reached in the safety application program,
SM560-S switches to DEBUG STOP state.
Valid PROFIsafe safety telegrams are generated in DEBUG RUN state. DEBUG RUN state is unsafe, thus,
the responsibility for safe process operation lies entirely with the organisation and person responsible for the
activation of DEBUG RUN (Non-safety) mode.
One can go back to a safe RUN state only using powering off/on or "reboot" PLC Browser command on
PM5xx Non-safety CPU.
