D-MAP RAM
If the whole D-MAP RAM is taken up with trendlog objects, a delta (differential)
download will no longer be possible.
The overall size of the free and used D-MAP RAM can be viewed with XWP,
Desigo CC or PXM20. The information concerned is stored in the device object
under the memory statistics property [MemStc].
Access rights management
Access rights are managed via USPRF. You can define a maximum of 10 user
groups and 20 users. 10 user groups and 6 users are already predefined as a
template (global chart).
22.4.2 LonWorks system controllers
Device combination: PXC00.D/-E.D + PXX-L11/12
Item Limit
LonWorks devices:
PXX-L11
PXX-L12
60* (e.g.: 5 Group Members are defined, that means 5 x 12 = 60 COV resources are needed)
120*
Max. number of integrated LonWorks devices covers third-party LonWorks devices.
Discipline I/Os [600] max. number of discipline I/O objects
Groups [50] max. Number of groups
Room members No limits
Group members Cross-disciplinary groups can have more than 5 destinations. The number of cross-disciplinary
groups depends on the COV client resources (max. 250). A different number of COVs is required,
depending on the group type. These must be multiplied by the number of destinations.
Calculation basis:
HVAC CHOGRP 1 COV client resource per destination
SPGRP* 12 COV client resources per destination
EMGGRP 1 COV client resource per destination
Lighting LIGHTGRP 2 COV client resources per destination
Blinds BLSGRP 4 COV client resources per destination
Building use USEGRP 3 COV client resources per destination
Room occupancy OCGRP 3 COV client resources per destination
LonWorks system controllers with physical I/Os and TX Open
Device combination: PXC50/100….D + PXX-L11/12
If the PXC50/100…D is used instead of the PXC00…D as a system controller,
physical I/Os can be integrated via TX-I/O modules and TX Open data points.
The reaction time can be greater for a larger number of physical I/Os or TX
Open data points, and depending on the complexity of the CFC program.
22.4.3 Automation stations with LonWorks integration
Device combination: PXC50/100/200…D mit PXX-L11
The modular automation stations PXC50/100/200.D and PXC50/100/200-E.D
allow the integration of LonWorks devices and third-party devices via PXX-L11
in addition to the use of I/O modules or third-party devices via TX Open.
The integration on PXC50…D is limited to a maximum of 10 LonWorks devices.
The integration of LonWorks devices for PXC100/200…D is limited by response
times.
