Controllers, 1 Redundancy Switch Module (RSM)
Honeywell
2 I/O Expansion
Rack
Includes: 1 S75S Scanner 2 module, 1 Power
Supply, and 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.
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) LEAD
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 (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
Required if using 2 or more I/O Expansion racks.
Provides connection of the private I/O Ethernet
100Base-T port on a (C75S) Controller Module to
the (S75S) Scanner modules. Switch not required
for connection to a single I/O rack.
Honeywell
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.
Honeywell or third-
party suppliers.
7 Shielded
Ethernet CAT5
cable
Connects I/O (S75S) expansion racks to (C75S)
controllers and/or to 10/100baseT Ethernet
switches. It also connects to 900 Control Stations
and PC SCADA software applications.
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.
9 RS-485 cable Shielded twisted pair cable connects Isolated
Controller port to field devices or PC with RS-485
convertor
