PXC5.E003 System Controller

Product Information: DesigoTM System Controller PXC5.E003

The DesigoTM System Controller PXC5.E003 is a programmable
system controller for integration of BACnet/MSTP, Modbus, and KNX
PL-Link devices. It has a communication BACnet/IP (BTL certified)
and a 2-port Ethernet switch for low-cost cabling. The system
controller integrates Modbus data points via RTU and / or TCP,
BACnet MS/TP devices, and KNX PL-Link bus to connect sensors and
operator units (including bus power). This system controller
operates on AC 24 V and can be mounted on standard rails or on the
wall using plug-in screw terminal blocks.

Functions:

• Freely programmable system controller.
• System functions (alarming, scheduling, trending, access
  protection with individually definable user profiles and
  categories).
• System controller for system networks with PXC3, PXC4, PXC5,
  PXC7 and DXR controllers over BACnet/IP, BACnet/SC, or BACnet
  MS/TP.
• Integrates third-party devices and systems.
• The following functions are available with KNX PL-Link bus:
  interface, generic object viewer for local data points and assigned
  devices via embedded web interface.
• Engineering and commissioning with the ABT Site Tool using
  graphical function charts.
• BTL tested BACnet communication on IP (BACnet/IP and BACnet/SC)
  or MS/TP, in compliance with the BACnet standard including B-BC
  profile (Rev. 1.15).
• Wireless connection for engineering and commissioning.
• Cloud connectivity for remote access.
• Integration of Modbus data points via RTU and / or TCP.
