3.2.4 Diagnosis
DANGER!
The diagnosis data is not safety-relevant and, thus, shall not be used in safety application program for
execution of safety functions.
Fig. 15 shows LED states of Safety I/O modules (AI581-S is used as an example), which can be observed
during the start-up of Safety I/O modules.

State 3 – End state of initialization
4
State 4 – Parameterisation is complete, but no
PROFIsafe communication yet
NOTICE!
External errors (wiring or sensor errors) in Safety I/O modules lead to the channel passivation ("0"
values are delivered). As soon as an external error is fixed and this is recognized by internal Safety
I/O module tests, Safety I/O module channels request an acknowledgement for their reintegration to
the normal safety process control mode. The user can acknowledge such channels using dedicated
Ä Chapter 4.3.5 "Instantiation and configuration of safety modules/Definition of variable
channel bits (
names" on page 177).
Safety I/O module error messages are aggregated together with other module error messages in PM5xx
CPU. The following two tables include a list of error messages related to Safety I/O modules.
