Connections

2.1

Local connection

The local connection is a peer-to-peer connection between one HMI-DM and one
Climatix 600 controller. The HMI-DM provides RJ45 connector on both sides for
local connection.
Two types of standard 8-wire twisted net cable can be used via RJ45 connector.
One type is shielded cable, and the maximum distance between HMI-DM and
controller is 50 m; the other is unshielded cable, and its maximum distance is 3 m.
Without additional power supply, one single Climatix 600/400 controller can only
supply one HMI-DM.
For detail information, refer to Mounting Instruction CB1M3940en.
2.2

Remote connection

HMI-DM can be connected to controller via process bus. It is possible to connect in
the same system several HMI-DM, controllers and other Climatix devices with
process bus functionality. Refer to CB1P3903en, section 10 "Climatix process bus"
for more information about network's characteristics and limit.
The connection via process bus is shown as follows:
