Not applicable.
–
No restrictions.
2
Not the same as the number of integrated devices ( PXC00.D/-E.D + PXX-L…).
3
LonWorks routers must not be used at the automation level.
4
Limit applies only if this device type is used exclusively.
6
For higher performance use a PXG3 instead of a PXC-E.D for the BBMD function.
7a
Limit for PXC00.D/-E.D + PXX-L11.
7b
Limit for PXC00.D/-E.D + PXX-L12.
8
Limit for PX devices without Desigo room automation. Do not exceed the number of PXC
devices per site.
9
The limit on the number of PX automation stations per internetwork can only be maintained
if no PX clients are used. PX clients limit the permissible number of PX per internetwork. The
values can be obtained by reference to the relevant automation station columns. The
restricted view option does not affect the system configuration of PX clients.
10
The number of temporary alarm receivers in a PX is a technical limit. The recommended limit
is lower. This takes account of the fact that additional devices may be connected for service
purposes.
11
The number of temporary alarm receivers in a PX is a technical limit. The recommended limit
is lower. This takes account of the fact that additional alarm receivers (third-party) may have
entries in this list.
12
Parallel engineering (commissioning ) is possible subject to the following restrictions:
- Node setup: Only one XWP per LonTalk/IP segment.
- Download and online operation: only one XWP for each automation station.
14
In pressurized rooms with or without fume hood, all automation stations of a room must be
connected to a switch in a starlike manner to ensure high availability.
15
Desigo room automation stations do not belong to a PX site (no primary copy function).
16
For the system configurations of the Desigo CC management platform, see
Desigo CC
System Description
(A6V10415500).
17
50: If Lon PX exists in the PX site. 100: If no Lon PX exist in the PX site (only IP PX).
18
These limits in the Desigo system refer in particular to Desigo Insight. The limits may be
significantly lower due to the PTP connection(s) outside the Desigo system and their
technical limitations. Examples of such limitations outside the Desigo system can include
available bandwidth for the PTP link or available modem speeds.
19
This limit can be exceeded if all BACnet devices are located within the same IP subnetwork,
or if no communication between the various BACnet/IP networks is required.
