In these networks the zone pairs 3 and 4 can be switched active.
To do this change the flags (dummies) against their sensors
(input parameter in FC2) and parameterize the zone pairs
in LS4-4 with the LS4Soft software. In this example only zone
pair 1 and 2 are considered.
Note
The memory bits (dummys) are default in OB 100.

Network 5 and Network 6
In this example a zone pair always becomes active when the
respective sensor (here NC) switches (i.e. is on "0" signal) AND
the other sensor (NC) or the dummy bits are on "1" signal. During
switching (e.g. from zone pair 1 to zone pair 2) this condition
is not true for a certain duration of time. During this time
the last set zone pair remains active!

This condition can (depending on the application) be a possible
hazard (e.g. if the sensor to be switched does not react) In
this example the status is recorded and compared with a parameterized
time. If this condition continues to be true after
this time has elapsed, this will be interpreted as an error and
the #ERR_SW_TIME bit will be set (see following figure).
