8.2.2 Predefined LTE filter table
The predefined LTE filter table is available in the Siemens area/line coupler
N140/13 from Version R2, and in the Siemens IP router N146 from Version R4.
The filter setting "Normal (route)" either blocks or routes the LTE telegrams from
the zones and zone addresses, as shown in the list.
LTE telegrams of the
following zone addresses
are…
Zones
Blocked Routed
Geographical zones
1)
1…110 111…126
Heat distribution zones
2)
1…15 16…31
Refrig distribution zones
3)
1…15 16…31
Air distribution zone 1…15 16…31
Boiler sequencing zone 1…8 9…16
DHW zone 1…15 16…31
Holiday/special day zone
4)
1…15 16…31
Outside temperature zone
4)
1…15 16…31
Solar zone
4)
1…15 16…31
Wind zone
4)
1…15 16…31
The zone address in the filter table with the attributes "Blocked" or "Routed" are
predefined and these attributes cannot
be modified.
1)
The geographical zones comprise:
− Geographical zone (apartm), … (Room), … (Subzone)
− Time switch zone (apartment)… (Room), … (Subzone
− Time-switch slave (apartment)
− Master/slave zone (apartm), … (Room), … (Subzone)
− QAW op.zone (apartment)
2)
The heat distribution zones comprise:
− Heat distr zone source side
− Heat distr zone consumer side
− Heat distr zone heating surface
− Heat distribution zone air heater
− Heat distrib. zone, primary distr.
− Heat distrib. zone, primary contr.
3)
The refrigeration distribution zones comprise:
− Refrig distr zone source side
− Refrig distr zone consumer side
− Refrig distrib. zone air cooler
− Refrig distr zone cooling surface
4)
In these zones only one devices transmits LTE telegrams to several devices.
Example: The device to which the outside temperature sensor is connected,
measures the outside temperature. Only this device transmits the outside
temperature value to the other devices which also need this value (multiple use
of sensor values).
