The PXC001.D system controller can integrate SCL via BACnet/LonTalk. The PXC001-E.D system
controller can integrate SCL via BACnet/IP. The PXA40-RS1 and PXA40-RS2 option modules support
additional data points.
The regional companies develop the necessary protocols themselves.
The hotel management system Fidelio can be integrated into Desigo via PX SCL.
See
PX SCL (CA2N9773).
PX LON
PX LON connects LonWorks networks to Desigo and maps Standard Network Variables (SNVT) to BACnet
data points. The main functions of PX LON are:
● Higher-level control and optimization functions, such as room and zone-based groups, time control, and
system functions, such as changeover, summer/winter compensation, etc.
● Alarm handling, device monitoring
● Trend storage
The PXC00.D system controller and the PXC50.D, PXC100.D and PXC200D automation stations can
integrate LonWorks devices via BACnet/LonTalk. The PXC00-E.D system controller and the PXC50-E.D,
PXC100-E.D and PXC200-E.D automation stations can integrate LonWorks devices via BACnet/IP. With the
PXX-L11 and PXX-L12 expansion modules you can connect 60 and 120 devices.
PX Open Platform SDK
HQ provides the PX Open Platform Software Development Kit (SDK) for experts in the regional companies.
21.3 Integration on field level
The integration of third-party devices and systems on the field level is appropriate:
● For communicative pumps, meters, etc.
● For small numbers of data points (10 to 100/160 data points)
TX Open is suitable for the integration of a few data points (from 10 to 160 data points). These data points
can be processed further in the automation system or used for visualization in Desigo CC.
● The TXI1.OPEN module supports up to 100 data points and has an RS232/RS485 interface.
● The TXI2.OPEN module upports up to 160 data points and has in addition an ethernet connection for
remote access, diagnosis and remote engineering.
● The TXI2-S.OPEN module supports up to 40 data points.
The TXI1.OPEN or TXI2.OPEN module is loaded with the protocol applications for Modbus/M-
Bus/GENIbus/G120P and then works as the Modbus/M-Bus/USS/GENIbus master. The values of the
Modbus/M-Bus/GENIbus/G120P data points and the status of the existing data connection with the data
points are transmitted to the automation station via the island bus and mapped to BACnet objects in the
automation station. This way, the Modbus/M-Bus/GENIbus/G120P data points can be made available to
all the devices and applications in the Desigo system.
The PXC50..D, PXC100..D and PXC200..D automation stations support TX Open. You can attach up to five
TX Open modules to one PXC automation station.
Xworks Plus (XWP) is used to engineer all solutions. Various compounds are available, e.g., for pumps,
variable speed drives and heat meters.
Predefined solutions allow for simple commissioning. Solutions for Grundfos, Wilo, Danfoss and G120P are
delivered as part of the HQ CAS Library. For M-bus and Modbus, sample solutions serving as device
description templates are provided (TX Open templates).
The following solutions on the TX Open platform are available:
● TX Modbus
● TX M-Bus
● TX G120P/SED2
● TX Grundfos via GENIbus
● TX Open platform (SDK)
TX Modbus
TX Modbus supports Modbus RTU and Modbus TCP, Wilo pumps and variable speed drives. TXI2.OPEN
supports 160 data points. They may be distributed in any fashion to the devices for the Modbus system.
The number of devices is only limited by the 160 data points.
See
TX Modbus Engineering Guide (CM110571).
