● Alarm handling, device monitoring
● Trend storage to record meter readings
The PXC001.D system controller can integrate M-Bus via BACnet/LonTalk. The
PXC001-E.D system controller can integrate M-Bus via BACnet/IP. The PXA40-
RS1 and PXA40-RS2 option modules support additional data points.
See
PX M-Bus (CM2N9774).
PX SCL lets you quickly develop simple protocol solutions. The script control
language from XWP is used with an interpretable environment and lets
engineers create a solution. The solution cannot be used for complex protocols
and solutions. It is used to develop other applications, such as local serial
printer driver and pager applications.
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 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.
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-
