Freely programmable automation stations for HVAC, building services plants, and system controllers.

 

  • BTL tested BACnet communication on IP (BACnet/IP and BACnet/SC) or BACnet MS/TP, in compliance with the BACnet standard including B-BC profile (Rev. 1.16)
  • Modbus TCP/RTU and BACnet MS/TP
  • The following functions are available with KNX PL-Link bus:
    • Communication with RDG2..KN room thermostats, sensors, and operator units
    • Plug-and-play connection of Siemens field devices with KNX PL-Link
  • Integration of wired M-bus meters via RS485 level-converter or onboard M-bus interface (EN 13757-2):
    • Offline and/or online engineering with ABT Site. No additional M-bus tool required
    • Primary and/or secondary device addressing
  • IT security including HTTPS, IEC-62443 4-2 (Security Level 2), and BACnet Secure Connect
  • BACnet Secure Connect support as BACnet/SC hub
  • WLAN interface for engineering and commissioning
  • System functions such as alarming, schedulers, trending, time sync, and life check
  • Grouping functionality e.g. common setpoints for room controls or energy demand
  • System functionality for integrated subsystem and devices
  • Integration of Modbus subsystems and devices via TCP and/or RTU: Data point mapping to BACnet/IP and supervisory functionality
  • Integration of BACnet MS/TP subsystems and devices: Supervisory functionality and routing to BACnet/IP
  • Cloud connectivity to Building X for remote access and data points time series

1) For details on engineering, see PXC4, PXC5 & PXC7 Planning overview, A6V13054435.

2) KNX PL-Link data points do not count as integration points. For KNX PL-Link, only the limits on BACnet objects are considered.

3) Depending on the behavior of the third-party MS/TP devices.
