Data communication

Ethernet (only for Pro and Pro+ versions)Danfoss AS-CX06 Lite
Programmable Controller - Data communication Point to point star topology with network hubs/switches. Each AS-CX device incorporates a switch with fail-safe technology.

  • Ethernet type: 10/100TX auto MDI-X
  • Cable type: CAT5 cable, 100 m max.
  • Cable type connector: RJ45

First access information
The device automatically acquires its IP address from the network via DHCP.
To check the current IP address, press ENTER to access the default settings menu and select Ethernet Settings.
Enter the IP address in your preferred web browser to access the web front- end. You will be directed to a login screen with the following default credentials:
Default User: Admin
Default Password: Administrator
Default Numeric Password: 12345 (to be used on LCD screen) You will be prompted to change your password after your initial successful login.
Note: there is not a way to retrieve a forgotten password.
RS485: Modbus, BACnet
RS485 ports are isolated and can be configured as client or server. They are used for fieldbus and BMS systems communication.
Bus topologyDanfoss AS-CX06 Lite Programmable Controller - Bus
topology Cable type recommendations:

  • Twisted pair with ground: short leads (i.e. <10 m), no power lines in proximity (min. 10 cm).
  • Twisted pair + ground and shield: long leads (i.e. >10 m), EMC- disturbed environment.

Max. number of nodes: up to 100

Wire length (m) Max. baud rate Min. wire size
1000 125 kbit/s 0.33 mm2 – 22 AWG

CAN FD
CAN FD communication is used for device-to-device communication. It is also used to connect Alsmart remote HMI via display port.

Installation of RS485 and CAN FD

  • Both fieldbuses are of two wire differential type, and it is fundamental for reliable communication to connect all the units in a network also with a ground wire.
    Use one twisted pair of wires for connecting the differential signals and use another wire (for example a second twisted pair) for connecting the ground. For example:Danfoss AS-CX06 Lite Programmable Controller - CAN
FD

  • The line termination must be present on both bus ends to ensure proper communication.
    The line termination can be installed in two different ways:
    1. Make a short circuit on CAN-FD H and R terminals (only for CANbus); 2. Connect a 120 Ω resistor between CAN-FD H and L terminals for the CANbus or A+ and B- for RS485.

  • The installation of the data communication cable must be performed correctly with sufficient distance to high voltage cables.Danfoss AS-CX06 Lite Programmable Controller - high voltage cables

  • The devices should be connected according to the “BUS” topology. That means that the communication cable is wired from one device to the next without stubs.
    If stubs are present in the network, they should be kept as short as possible (<0.3 m at 1 Mbit; <3 m at 50 kbit). Note that remote HMI connected to the display port makes a stub.Danfoss AS-CX06 Lite Programmable Controller -
display port makes

  • There must be a clean (not disturbed) ground connection between all devices connected in the network. The units must have floating ground (not connected to earth), which is tied together between all units with the ground wire.

  •  In case of three conductor cable plus shield, the shield must be grounded in one location only.Danfoss AS-CX06 Lite Programmable Controller - conductor cable

(1) A higher DC voltage can be applied if the control is installed in an application where the manufacturer declares a reference standard and a voltage level for accessible SELV/ PELV circuits to be considered non-hazardous by the application standard. That voltage level can be used as power supply input though 60 V DC must not be exceeded.

Installation considerations

  • Accidental damage, poor installation, or site conditions can give rise to malfunctions of the control system, and ultimately lead to a plant  breakdown.
  • Every possible safeguard is incorporated into our products to prevent this. However, a wrong installation could still present problems. Electronic controls are no substitute for normal, good engineering practice.
  • During installation ensure that proper method is made to prevent a wire to get loose and create a potential risk in regards to shock or fire.
  • Danfoss will not be responsible for any goods, or plant components, damaged as a result of the above defects. It is the installer’s responsibility to check the installation thoroughly, and to fit the necessary safety devices.
  • Your local Danfoss agent will be pleased to assist with further advice, etc.
