Key No. Component
Name
Description Source
1 Controller
(Local) Rack
Includes: Rack, Power Supply, Controller Module,
and I/O modules
Honeywell
2 I/O Expansion
Rack
(C50S/C70S
CPUs only)
(Optional) Includes: Rack, Power Supply, Scanner
Module, and I/O modules
Honeywell
3 Operator
Interface
900 Control Station operator interface
communicates via Ethernet or RS-485 serial link
Honeywell
4 PC
Configuration
Tool
(Optional) PC (laptop or desktop) connects to
RS-485 or Ethernet port(s) on any (one) Controller
module. Includes Honeywell Designer Software
(configuration software).
PC & USB to RS485
convertors are from
third-party suppliers.
Configuration software
is from Honeywell.
5 HMI (Human-
Machine
Interface)
(Optional) PC link to Ethernet network, which may
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).
PC is from third-party
supplier. HMI software
is available from
Honeywell (PlantScape
or SpecView32) or
from third-party
supplier.
6 Ethernet
100Base-T
Switch
Enables connection of the private Ethernet
100Base-T port on a (C50S/C70S CPU only)
Controller Module to the (S50S) Scanner modules
on 2, 3, or 4 I/O Expansion racks. (If a single I/O
expansion rack is connected directly to a Controller
Module, the Switch is not required.)
Honeywell Qualified
Switch from Honeywell
or third- party suppliers
6a Ethernet
10/100Base-T
Switch or
Router
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, brouters, servers, and other
devices in wider networks.
Third-party suppliers.
7 Shielded CAT5
Ethernet cable
Connects I/O expansion racks (S50S only) to
controllers (C50/C70 CPU only) and/or to
10/100baseT Ethernet switches.
Honeywell or Third-
party suppliers
Fiber Optics
Cable
Controller to remote rack distance up to 750m
(2460 ft.) with one fiber cable. Distances up to
1500m (4920 ft.) are possible with a fiber switch
used as a repeater at the midpoint.
8 Shielded CAT5
Ethernet cable
Connects devices in Ethernet Open Connectivity
network to 900 Control Stations and PC SCADA
applications.
Honeywell or Third-
party suppliers
10 RS-485 cable Shielded twisted pair cable connects Isolated
Controller port to field devices or PC with RS-485
convertor
