This group object is enabled if the Enable function Forced operation/Block parameter is set to the required option (Forced
operation 1 bit/Forced operation 2 bit/Block) in X Functions template (group x/ballast x) (Forced operation/Block/Burn-in/Partial
failure), p. 102. Depending on the parametrization this group object can therefore assume only one of the following functions:
•
•
•
The Forced operation 1 bit group object forcibly operates group x or ballast x, e.g. by higher-level control. The value of the
group object directly defines the forced position of the group:
Telegram value:
The Forced operation 2 bit group object forcibly operates group x or ballast x, e.g. by higher-level control. The value of the
group object directly defines the forced position of the group:
Telegram value:
Even during forced operation the brightness value of the group or ballast is calculated when an incoming telegram arrives,
but not displayed. Dimming speeds are not taken into account in the calculation, i.e. the immediate end values are stored in
the background. When forced operation is complete the brightness values updated in the background are set.
A dim, scene or staircase lighting recall will not be reinitiated.
After a download, the Forced operation group object has the value 0. Forced operation is not activated.
The State on bus voltage recovery is parametrizable.
The Block group object is used to block a group or ballast to prevent unwanted operation. Any further incoming telegrams are
ignored but are updated in the background. When the group is released, the updated brightness values are set and incoming
telegrams immediately processed again.
Telegram value:
A block during the staircase lighting time immediately blocks the group or ballast and freezes the brightness. After unblocking,
the Staircase lighting function continues with dimming (advance warning). If the Slave function was active before the block,
it is reinitiated.
After a KNX bus voltage recovery or download the block is set as it was before the failure or download. If the Block function is
no longer required, the group must be released and the object value set to 0.

Block
0 = The group or ballast is not forcibly operated; existing forced operations are removed.
1 = The group or ballast is forcibly operated and switched on at the parametrized brightness value.
Forced operation is active.
0 or 1 = The group or ballast is not forcibly operated; existing forced operations are removed.
2 = The group or ballast is forcibly switched off. Forced operation is active.
3 = The group or ballast is forcibly operated and switched on at the parametrized brightness value.
Forced operation is active.
0 = Remove block
1 = Activate block
