AC500-S safety modules
Generic safety I/O module behavior > Safety I/O module states
The fail-safe value "0" is still transferred to the safety CPU for all passivated input channels. All
passivated output channels have a state of "0". The PROFIsafe diagnostic bits for all channels
have the state of "0" to indicate that fail-safe values are transferred.
The OA_Req_S bit is reported as "1".
As soon as the safety application of the safety CPU sets OA_C (positive edge), the safety I/O
module goes to RUN (ok) state if no further errors are detected. One has to send the positive
edge to the safety I/O module until OA_Req_S starts delivering "0".
PROFIsafe status bits in the F-Host for safety I/O module:
OA_Req_S = 1
FV_activated_S = 1
Device_Fault = 0
Process data bits in the safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0
SAFE STOP
The safety application execution was stopped. No PROFIsafe communication is possible.
This state is reached if an error of severity level 1 (e.g., CPU test, RAM test, etc. failed) took
place.
This state can be left only through powering off/on of the process power supply (24 V) or reboot
command from non-safety CPU or communication interface module.
PROFIsafe status bits in the F-Host for safety I/O module:
OA_Req_S = 0
FV_activated_S = 1
Device_Fault = 0
Process data bits in the safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0
