Interlocking function
The interlocking function is used to verify that an output is truly activated, i.e. by "combining"
an output with an input (feed-back from the equipment controlled by the corresponding
interlocking output).
15.1
Programming of interlocking function
Up to 400 Interlocking Combinations per CIE and up to 4000 in a system, can be
programmed using EBLWin.
Note
: One Interlocking Combination (input, output and area) must be included in /
connected to one CIE. An input and an output can only be used in one combination.
Area
and
Point
fields are unique identifiers for each paired interlocking combination
synonymous to Zone-Address. They are presented in this format NNN-NN with the first 3
digits representing the Area and the last 2 digits representing the Point. The Area numbers
range from 1-999 and the Point numbers range from 1-99
It is advantageous
to have a numbering system planned correlating to the location (“Area”)
when assigning a
Name
to the interlocking combination. Having some form of structure to
the numbering will greatly help organise the SSD file and make it easier to understand and
assist with troubleshooting later. One should also consider including all I/O devices into this
numbering structure so that it will be easier to select from the list of interlocking
combinations.
A
Filter Function Box
as shown in Figure 34 below, is available to assist with listing only
those interlocking combinations of interests. This will become more powerful when some
sort of numbering structure is in place. Figure 34 was from a list of 100 interlocking
combinations, typing in “1”
112
in the filter function box quickly narrows down the lists with
anything containing “1”. One can see the usefulness of having a planned numbering
structure in place from this example should all interlocking combinations on containing 1
were called for.
Figure 34 Filter function
Available interlocking inputs and/or outputs will appear in the EBLWin dialog box shown in
Figure 34 page 96, only when each input and output have been configured with Type =
Interlocking.

Filtering search texts are case sensitive. For this reason, ensure that naming convention is consistent throughout.
