AC500-S safety modules
Generic safety I/O module behavior > Safety I/O module states
RUN (module
passivation):
alternating
blinking of
ERR1 and ERR2
LEDs
PROFIsafe communication is up and running. The safety application is running with a present
module error.
The module and, as a result, all its channels are passivated. Possible reasons for module passi-
vation are:
● PROFIsafe communication failure (CRC error)
● PROFIsafe watchdog timeout exceeded
● Undervoltage/overvoltage detected (Device_Fault status bit = 1)
The fail-safe value "0" is transferred to the safety PLC for all passivated input channels, if the
connection to the PROFIsafe F-Host is possible. The safety application continuously attempts to
establish a communication to the safety CPU, if the communication is broken. All passivated
output channels have a state of "0".
A state transition to another RUN mode is only possible if the detected error is gone.
PROFIsafe status bits in the F-Host for safety I/O module (if communication is possible!):
OA_Req_S = 0
FV_activated_S = 1
Device_Fault = 1 (in case of undervoltage/overvoltage detected) and/or CE_CRC = 1 (in case of
communication error) and/or WD_timeout = 1 (in case of watchdog timeout)
Process data bits in the safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0
