Contact position if safety priority 1
Options:
This parameter determines the switch position of the output if the safety condition Safety priority 1 (setting
undertaken in parameter window Function, page 35) has been fulfilled.
The 1 bit communication object Safety priority 1 is used as a master for the safety position. The switch po-
sitions ON, OFF and unchanged are available.
•
inactive: The state of the communication objects Safety priority 1 has no effect on the output.
Contact position if forced operation
Options:
The forced operation relates to the 1 bit or 2 bit Forced positioning communication object of the output that
is available to every output.
•
inactive: The state of the communication object Forced Positioning has no effect on the output.
•
unchanged via 1 bit object, ON, via 1 bit object and OFF, via 1 bit object: The 1 bit communication ob-
ject Forced positioning determines the switching state of the output during forced operation.
•
switch position via 2 bit object: The 2 bit communication object Forced positioning is enabled. The val-
ue of the telegram sent via the 2 bit communication object determines the switch position, see the fol-
lowing table:

Description
If the communication object Forced positioning receives a telegram with
the value 0 (binary 00) or 1 (binary 01), the output is enabled and can be
actuated via different communication objects.
If the communication object Forced operation receives a telegram with
the value 2 (binary 10), the output is switched off and remains disabled
until forced operation is again switched off.
Actuation via another communication object is not possible as long as the
forced operation is activated.
The state of the output at the end of forced operation can be pro-
grammed.
If the communication object Forced operation receives a telegram with
the value 3 (binary 11), the output is switched on and remains disabled
until forced operation is again switched off.
Actuation via another communication object is not possible as long as the
forced operation is activated.
The state of the output at the end of forced operation can be pro-
grammed.
