This communication object is enabled if in parameter window
been selected with the option yes and the parameter Contact position if forced operation has been selected with 1 bit object.
If the communication object receives the value 1, the output is forcibly set to the parameterized switch position, which has
been set in the parameter window
operation is ended. This is then the case when a 0 is received via the communication object Forced operation .

This communication object is enabled if in parameter window
been selected with the option yes and the parameter Contact position if forced operation has been selected with 2 bit object.
Output X can be forcibly operated via this communication object (e.g. by a higher-level control). The value of the communica-
tion object directly defines the forced position of the contact:
At the end of the forced operation, a check is performed to see if one of the three functions Safety Priority x is active. If
necessary, the contact position is set by the active safety priorities. If no function Safety Priority x is active, the contact is set
as parameterized in parameter window A: Safety in parameter Reaction when forced operation and all Safety Priority x end.
71
This communication object is always enabled.
The communication object value shows the contact state when the contact is open.
Should a current flow be detected with an opening of the contact initiated via the KNX, contact welding or manual switch on
has occurred (contact fault). The evaluation of whether a current flows occurs about one second after a contact is opened. The
current is safely detected should a measurable current (about 25 mA starting current) flow. A prerequisite for correct evalua-
tion is switching via the KNX.
