Note!
If an error (e.g. a discrepancy error) occurs at a safe input to which the OMS
function has been assigned, normal operation will be selected. This
corresponds to the OFF state. The "ME" LED is blinking and STO is not
activated. The special operation can only be selected again when the error has
been eliminated and acknowledged.
From SM301 V1.3 onwards, the switching level at the digital input which
determines special or normal operation can be set via the safe
parameterisation.

Note!
When the OMS bit is received via the safety bus, the value 0 (normal
operation) is assumed in case of passivation. In special applications (e.g. safety
door, request of OMS, i.e. open safety door = special operation) this must not
cause a dangerous state by automatic restart.
