DBLOCK signal
The DBLOCK signal is located in the low byte of TZW1 (bits 6 to 7). It has an enumerative structure
and is assigned the obstruction detection (DBLOCK).

value
Name Description
0 None There is no obstruction
1 In opening direction An obstruction was detected in the opening direction
2 In closing direction An obstruction was detected in the closing direction
3 Reserved
DBLCWAIT signal
The DBLCWAIT signal is located in the high byte of TZW1 (bit 9). It has a binary structure and is
assigned the special obstruction mode "wait mode".

0 Wait mode inactive See section Wait mode (Page 90) for a signal description
1 Wait mode active See section Wait mode (Page 90) for a signal description
DPOS signal
The DPOS signal is located in the high byte of TZW1 (bits 9 to 15). It has an enumerative structure
and is assigned the current door position (DPOS) in %.
Table A-28 DPOS signal
DPOS signal val‐
ue
Name Description
0 … 100 Door position Door position in %
Note: The value is only valid in normal mode.
The 100 % and 0 % door positions can only be reached in con‐
junction with the "open" or "close" drive orders.
The 99 % and 1 % door positions correspond to fully open or
fully closed without an active drive order.
Values between 99 % and 1 % specify the door position as a
percentage value.
127 or 7F
hex
is sent (>100 %) if no valid position value is avail‐
able.
In partial opening mode, the door position continues to be
referred to the real door width. The values 100 and 99 % are not
reached in partial opening mode.
