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 ControlEdge 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 ControlEdge 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.
Third-party suppliers or
Honeywell
10
Serial Interface
Cable
For legacy system, Null modem cable, up to 50’ (15.24m)
(PC modem cable if used with Modems.)
For new system, RS-485 to USB converter connects
galvanically isolated RS-485 port to USB port.
