connects from the RS-232 serial port of the
Controller Module to a serial port on the PC

connects from the galvanically isolated RS-485
port of the Controller Module using an external

(Optional) PC link to Ethernet network, which may
Machine include other HMIs, other ControlEdge HC900
Interface) Controllers, and other networks (including Internet).
Typically includes HMI operating software.
May also include Designer Software (configuration
tool and utility software).
Required if using 2 or more I/O Expansion racks.
managed Provides connection of the I/O Ethernet 100Base-T
Ethernet port on a Controller Module to the Scanner
modules. Switch not required for connection to a
Switch single I/O rack.
Ethernet Enables inter-connection of several 10/100Base-T
Ethernet devices in an Ethernet network. Devices
Switch or include other ControlEdge HC900 Controllers,
HMIs, and can also include routers, servers, and
other devices in wider networks. Use of a properly
configured firewall provides a more robust network
limiting exposure to uncontrolled network traffic.
Connects I/O expansion racks to controllers and/or
to 10/100baseT Ethernet switches. It also connects
to 900 Control Stations and PC SCADA software
applications.
For legacy system, Null modem cable, up to 50'
RS-232
(15.24m) (PC modem cable if used with Modems.)
For new systems, RS-485 to USB converter,
connects galvanically isolated RS-485 port to USB
port.
