9.4.1 LCP Status Messages
This section describes the LCP status messages related to
the safety option. The set of messages is different
depending on whether or not a safe fieldbus is enabled.
Table 9.2 contains messages that are shown regardless of
the safe fieldbus state. Table 9.3 contains messages that
are shown only when the safe fieldbus is disabled.

130BE091.10
The source that triggered the
safety condition has ceased,
but the safety option is
waiting for the reset signal to
continue normal operation.
The LCP shows this message
only if the manual restart
behaviour is selected for the
digital input.
The LCP does not show this
message when the PROFIsafe
control word activates the
safety function, since the
PROFIsafe configuration uses
automatic restart behaviour.
