Name
Includes: Rack, 2 Power Supplies, 2 C75
Controllers, 1 Redundancy Switch Module (RSM)
Includes: 1 Scanner 2 module, 1 Power Supply, and
Rack up to 4, 8, or 12 I/O modules. Optional second
Power Supply and Power Status Module (PSM) on
8- and 12-slot I/O racks.
communicates via Ethernet or RS-485 serial link

PC For legacy system- The PC configuration tool
connects from the RS-232 serial port of the
Controller Module to a serial port on the PC
Interface
 For new system – The PC Configuration tool
option)
connects from the galvanically isolated RS-485
port of the Controller Module using an external
Honeywell qualified RS-485 to USB converter.
(Optional) PC link to Ethernet network, which may
Machine include other HMIs, other HC900 Controllers, and
other networks (including Internet).
Typically includes HMI operating software.
May also include Designer Software (configuration
tool and utility software).
Required if using 2 or more I/O Expansion racks.
Provides connection of the I/O Ethernet 100Base-T
Ethernet port on a Controller Module to the Scanner
modules. Switch not required for connection to a
Switch single I/O rack.
Ethernet Enables inter-connection of several 10/100Base-T
Ethernet devices in an Ethernet network. Devices
include other HC900 Controllers, HMIs, and can
also include routers, servers, and other devices in
wider networks. Use of a properly configured firewall
provides a more robust network limiting exposure to
uncontrolled network traffic.
Connects I/O expansion racks to controllers and/or
to 10/100baseT Ethernet switches. It also connects
to 900 Control Stations and PC SCADA software
applications.
For legacy system, Null modem cable, up to 50'
RS-232
(15.24m) (PC modem cable if used with Modems.)
For new systems, RS-485 to USB converter,
connects galvanically isolated RS-485 port to USB
port.
