Table 3 – Descriptions of Major Redundancy Components
Name
Includes: Rack, 2 Power Supplies, 2 C75S
Controllers, 1 Redundancy Switch Module (RSM)
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.
900 Control Station operator interface
communicates via Ethernet or RS-485 serial link
(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).
(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).
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.
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.
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.
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.
Shielded twisted pair cable connects Isolated
Controller port to field devices or PC with RS-485
convertor
