HMI@Web
The IP service interface provides access to the same information over web as on
the local HMI.
The HMI@Web can be operated on the Explorer as the corresponding mapping file
(HMI4WEB) loaded to controller according authorization needed.
Climatix IC
After the TCP/IP is set up, configure the IC cloud with system object “CLS-Config”
if C400 (POL467/468) can be connected to the Internet. The corresponding
mapping file must be loaded to controller to implement the watch-page for remote
IC cloud.
Note: Perform ApplicationSave after the IC cloud is set up and connected.
Modbus TCP/IP
Through the Ethernet, Modbus TPC/IP master and slave modes are supported.
BACnet IP
Modbus BACnet is supported over the Ethernet and uses the same mapping
principle as BACnet MSTP.
Notes:
The above protocols can work at the same time on the TCP/IP interface, but the
network setup must be considered to avoid network congestion.
6.6 Extension interface
Features
The Climatix POL46X controller’s extension interface (RS485) supports extension
IO modules and third-party Modbus slave devices.
The extension IO requires an external power supply; we recommend using the
same power supply for the C400 controller.
Terminal assignment
The following illustration shows the identification of the terminals for Climatix
controllers.
Connection example
Note: total cable length for third-party devices should not exceed 30 m.
