Control Station
900 Control Station operator interface communicates
via Ethernet or galvanically isolated RS-485 serial link
Honeywell

PC
Configuration
Tool (Serial
connection
option)
 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
 For new system – The PC Configuration tool
connects from the galvanically isolated RS-485 port
of the Controller Module using an external
Honeywell qualified RS-485 to USB converter.
PC is from third-party
supplier. Configuration
software is from
Honeywell. RS-485 to
USB converter is a third
party device available
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
(Experion HS or
SpecView32) or from
third-party supplier.
6
Qualified un-
managed
Ethernet
100Base-T
Switch
Enables connection of the private Ethernet 100Base-T
port on a Controller Module to the Scanner modules
on 2, 3, or 11 I/O Expansion racks. (C50/C70 CPU
only) (If a single I/O expansion rack is connected
directly to a Controller Module, the Switch is not
required.)
Qualified third party
devices available from
Honeywell
6a
Ethernet
10/100Base-T
Switch or
Router/Firewall
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.
Third-party suppliers.
7
Ethernet CAT5 shielded cable
Connects I/O expansion racks
(C50/C70 CPU only) to controllers
and/or to 10/100baseT Ethernet
switches. 10’or 20’ (3.04 or 6.08m)
Third-party suppliers or
Honeywell
Fiber Optics Cable
Connects I/O expansion racks
(C50/C70 CPU only) to controllers
with fiber switch.
8
Ethernet CAT5
shielded cable
Connects devices in Ethernet Open Connectivity
network to 900 Control Stations and PC SCADA
applications.
