Operating states

INIT and IDLE state
The INIT and IDLE states are waiting or rest states of the PSENvip and are triggered by an
inactive safety controller. PSENvip is not ready for operation in INIT and IDLE state; i.e. re-
quests from the web interface or the add-on module PSENvip IPM will not be processed.
}
Switching to INIT state after a restart
After the supply voltage is switched on (restart), PSENvip initially switches to INIT state.
PSENvip exits INIT state as soon as the safety controller signals the operating state
"Device in RUN state without error". After the initialisation process and various start-up
tests, PSENvip switches to RUN state, provided all devices are operating without error.
} Switching from RUN to IDLE state
PSENvip switches from RUN state to IDLE state as soon as the safety controller is no
longer in the operating state "Device in RUN state without error". This is the case, for ex-
ample, when there is an error, after a reboot command, stop command, reset command
or when downloading a PSS 4000 user program.
