10.11 Line block trigger
The transmission of Lines by means of long-distance lines takes place in fixed blocks of 8 lines each.
[ 1 - 8] [ 9 - 16] [17 - 24] [ 25 - 32] [ 33 - 40]
[41-48] [49 - 56] [57 - 64] [ 65 - 72] [ 73 - 80]
[81-88] [89 - 96] [97 -104] [105 -112] [113 -120]
A Block line is not transmitted if the state of a
Line
changes within a block. This static behavior can lead
to problems if, for example, the connection between networked systems is disrupted and the state of a
Line
changes in the source system. When the connection is restored, the states of the lines remain
inconsistent with each other until a fresh change takes place to any
Line
within the block.
The
Line block trigger
program can counteract the problem and transmit selected blocks cyclically.

10.12 Special trigger lines
The use of special lines can be activated in the
Long distance line
line pool
option. (Range 1 to 255 lines)
This is only possible in the case of long-distance line transmission. Transmission takes place entirely as a
Single line by a single special telegram type.
As is the case with a Block line, the state of a Special line is only transmitted in the event of a change of
state. This static behavior can lead to problems if, for example, the connection between networked
systems is disrupted and the state of a Special line changes in the source system. When the connection
is restored, the state of the lines remains inconsistent in relation to each other until a fresh change of
state takes place.
The
Special trigger lines
program can counteract the problem and can once again begin transmitting the
states of the lines cyclically in selected areas.
Address
