The integration of third-party devices and systems on the automation level is appropriate when:

  • Cross-communication to other PX or BACnet devices is needed
  • System functions (e.g., alarms, trends, schedulers) are needed

The PX Open Platform comprises:

  • PXC001.D system controller for the integration of KNX, Modbus, M-Bus and SCL via BACnet/LonTalk
  • PXC001-E.D system controller for the integration of KNX, Modbus, M-Bus and SCL via BACnet/IP
  • PXA40-RS1 and PXA40-RS2 option modules for additional data points

The automation stations have interfaces to RS232, RS485 and KNX.

Xworks Plus (XWP) is used to engineer all solutions. Various compounds and blocks are available.

The following solutions on the PX Open platform are available:

  • PX KNX
  • PX Modbus
  • PX M-Bus
  • PX SCL
  • PX RS-Bus
  • PX Pronto
  • PX Open Platform (SDK)

The platform for integrating LonWorks compatible third-party devices consists of:

  • System controller PXC00.D and automation station PXC50.D, PXC100.D or PXC200.D for integrating LonWorks devices via BACnet/LonTalk
  • System controller PXC00-E.D and automation station PXC50-E.D, PXC100-E.D or PXC200-E.D for integrating LonWorks devices via BACnet/IP
  • PXX-L11 and PXX-L12 expansion modules for 60 and 120 LonWorks devices

PX KNX

PX KNX connects KNX networks with Desigo and maps the group addresses to BACnet datapoints. PX KNX can handle the following main tasks:

  • Data compression on the automation level (group functions)
  • Time control
  • Alarming, device monitoring
  • Trend storage
  • Mapping the Desigo RXB applications to BACnet for operating and monitoring

PX KNX supports the integration of:

  • KNX S mode third-party devices
  • RDF, RDG and RDU room thermostats
  • RXB room automation stations

The PXC001.D system controller can integrate KNX via BACnet/LonTalk. The PXC001-E.D system controller can integrate KNX via BACnet/IP. PX KNX is preinstalled on PXC001..D controllers.

PX Modbus

PX Modbus connects Modbus devices or networks supporting the Modbus protocol to the Desigo system and maps their data points to BACnet data points. PX Modbus is particularly suitable for integrating industrial controls or chillers and linking them to the automation process.

The PXC001.D system controller can integrate Modbus via BACnet/LonTalk. The PXC001-E.D system controller can integrate Modbus via BACnet/IP. The PXA40-RS1 and PXA40-RS2 option modules support additional data points.

See PX Modbus (CA2N9772).

PX M-Bus

PX M-Bus connects the M-Bus consumption meters to the Desigo system and maps meter readings and device-related meter information to BACnet data points. PX M-Bus handles the following main activities:

  • Measurement of consumption data and remote monitoring of max. 250 consumption and heat meters
  • Compression of data from consumption and heat meters at the automation level
  • 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

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

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.
