APPLICATION

CPO-PC400 is a new and advanced plant controller of the

ComfortPoint™ Open (CPO) Plant Controller family. It is an

Ethernet-based, freely programmable, and native BACnet®

Building Controller (B-BC).

CPO-PC400 is designed for a wide variety of complex

applications. This device features numerous RS485

communication interfaces, two standard Ethernet

interfaces, an MMI interface, and two USB interfaces.

CPO-PC400 can be mounted on either a DIN rail or remote

mounted in a horizontal or vertical position.

FEATURES

• Conforms to BACnet Standard 135 protocol version

1.14 (ISO 16484-5).

• Three pairs of LEDs indicating the transmission and

reception (respectively) of data via the RS485

interfaces 1.2. and 3.

• Ring LED to show the operational status of the

controller.

• Two Ethernet connectors with status LEDs.

• An MMI interface to connect with the CPO-MMI

device.

• Four RS485 interfaces to support Panel bus, BACnet

MS/TP, Field Bus, Modbus, M-Bus, CP-IO protocols,

and C-Bus data sharing.

• Built-in advanced diagnostics software facilitating

troubleshooting.

• FRAM to store the live data for the controller

including storing last known values when power is

removed.

• DDR3L for Random Access Memory.

• EMMC for program storage and boot flash memory.

• UTF-8 and UCS-2 character encoding formats are

supported.

• Supports Peer-to-Peer communication.

• A reset button to restore the factory default settings.

• Removable terminal blocks with Push-in or Screw

terminals.

• Built-in Webserver with HTML5 graphics support.

• A micro USB and a USB Type A ports.
