BACnet IP and BACnet MS/TP must not be operated at the same time (they are mutually exclusive). An address conflict could arise in the BACnet network.
Wire lengths
Interface | Wire lengths |

Third-party bus |
|
Service interface | Max. 3 m |
Signal wiring | Max. 80 m |
Be aware that the cable resistance and the influence of EMC as well as the hum is increasing with the cable length and has an impact on the accuracy of the analogue value.
If the maximum cable length can be reached in an application depends on factors like selection of cable type, -dimension, shielding, wiring, distance to high power devices, the requirements regarding measurement and control accuracy etc. and is in the responsibility of the customer.
Cable types
Interface | Specification |
---|---|
Ethernet | Always screened:
|
Process bus | Shielded, twisted pair: 0.5…1.5 mm2 (as per KNX specification) |
Peripheral bus | 4-wire (2 wires as twisted pair), shielded, if >3 m |
Third-party bus | 2 or 3-wire, twisted, shielded, if >3 m |
