Generic Safety I/O module behaviour > Safety I/O module states
To Description
RUN (ok) Safety I/O module comes to this state directly
after INIT during a normal start-up
INIT Powering off/on
RUN (module PROFIsafe watchdog, PROFIsafe communication
passivation) error or undervoltage/overvoltage was detected
directly after INIT.
The Safety I/O module can reach this state also
after powering off/on the Safety I/O module if
Safety CPU with PROFIsafe F-Host continues
running and brings Safety I/O module to a fail-
safe RUN (module passivation) state after pow-
ering off/on
INIT Powering off/on
SAFE STOP Fatal error(s) (CPU test, RAM test, etc. failed)
took place
INIT Powering off/on
RUN (channel Channel error was identified by the Safety I/O
passivation and module. The tests (whenever it is possible) are
reintegration) continued for the given channel to be able to see
if the error is gone (e.g., wiring error was cor-
rected). As soon as the error is gone, the module
sets "Reintegration request" bit = "1" for the given
channel.

The channel error is gone.
"Reintegration request" bit = 1 is set for the
given channel by the Safety I/O module.
"Acknowledge reintegration" bit (positive
edge) is set by PROFIsafe F-Host for the
given channel
