Bus Connection Between The Controllers, The Gateway And The Cms - Carrier CCU Regelungshandbuch

14 - BUS FOR CONNECTION TO A CMS BACNET IP OR MSTP

14.1 - Bus connection between the controllers, the gateway and the CMS

Modbus:
The distance between the gateway and the last controller must be less
than 1000 metres.
■ A maximum of 1 cabinet can communicate with the BacNet
gateway
■ The communication cable to be used must be:
- AWG24 - 22 type (1 shielded twisted pair)
■
Please note that, beyond a certain distance and depending on the
cabling carried out, it may be necessary to use additional equipment (not
provided - e.g. polarisation device, etc.) It is strongly recommended that
the distance between the gateway and controller is limited.

BACnet output MSTP
BACnet MSTP:
■ The communication cable to be used must be: AWG22
type (3 twisted shielded wires). A cable with 2 pairs must also
be used (1 pair for communication and 1 of the 2 wires from
the other pair for shared use)
■
The maximum length of a section is 1500 metres (at
38400 bauds and with a AWG22 cable)
■ The connections on the BACnet MSTP side must
observe the restrictions imposed by the BACnet association
(continuity of shielding, end of line terminating resistors, etc.).

BACnet IP:
■ The distances must observe the specifications
recommended in the Ethernet IP networks
■ The communication cable to be used must be a
minimum of CAT 6. We recommend using a paired shielded
cable (type S/FTP)
■
The network cable must be a "straight through" type
