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).

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".

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 %.

Description
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 is sent (>100 %) if no valid position value is avail‐
hex
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.
