Station Manager OperationThe Ethernet Interface contains features that support LAN
management activities such as network performance
measurement, status information, and fault diagnosis. Some
of these features are accessed via the Station Manager, a
portion of the Ethernet Interface operating firmware that
responds to user commands. The Station Manager operates
locally via an ASCII terminal or terminal emulator connected
to the dedicated Station Mgr (RS-232) serial port, or
remotely over the Ethernet LAN. Refer to the PACSystems
TCP/IP Ethernet Communications Station Manager Manual,
GFK-2225 for complete information on the Station Manager.
Each RX7i Ethernet interface provides a dedicated RS-232
serial port for local Station Manager use. The Ethernet
Interface does not use this port for firmware upgrades. See
“Firmware Upgrades” on page 8 for firmware upgrade
details.
RJ-45 Ethernet Network Ports
Caution
The two ports on the Ethernet interface must
not be connected, directly or indirectly, to the
same device. The hub or switch connections in
an Ethernet network must form a tree and not a
ring; otherwise duplication of packets and
network overload may result.
Note: The CPU module has two RJ-45 connectors but
only one IP address.
Each RX7i Ethernet interface contains two eight-conductor
RJ-45 shielded twisted pair Ethernet ports, labeled Port 1
and Port 2, for connection to either a 10BaseT or
100BaseTX IEEE 802.3 network. Either shielded or
unshielded twisted pair cable can be attached to a port.
Each Ethernet port automatically senses whether it is
connected to a 10BaseT or 100BaseTX network, half-duplex
or full-duplex. The user does not configure the network type.
(The automatic negotiation of speed and/or duplex mode can
be overridden by using AUP settings.) Standard twisted pair
Ethernet cable is used for connection to other devices.
Category 5 cable is required for 100BaseTX operation.
Each network port automatically operates in normal or
crossover mode. This capability allows directly wiring the
Ethernet interface to another device without an intervening
network hub/switch, and without a special crossover cable.
This allows you to connect RX7i Ethernet interfaces in a
daisy chain arrangement. Care should be taken when using
daisy chaining, since power loss or reset at an Ethernet
interface will cause loss of communication to devices

downstream from that Ethernet interface in the daisy chain.
Restarting the Ethernet interface (using the Ethernet Restart
pushbutton, for example) also disrupts daisy chain
communication.

Configuration
The RX7i CPU and I/O system is configured with Proficy
Machine Edition PLC-Logic Developer programming
software.
The CPU verifies the actual module and rack configuration at
power-up and periodically during operation. The actual
configuration must be the same as the programmed
configuration. Deviations are reported to the CPU alarm
processor function for configured fault response. Refer to the
Proficy Machine Edition Logic Developer-PLC Getting
Started Manual, GFK-1918 and the online help for a
description of configuration functions.
Ethernet Configuration
Essential network addresses for an Ethernet Interface are
set up using the Machine Edition configuration software and
stored to the CPU. These addresses must be properly
configured before the Ethernet Interface can be used by your
application. The configuration process is described in the
TCP/IP Ethernet Communications for PACSystems User’s
Manual, GFK-2224.
For initial installation when there is no IP addressing
information in the RX7i Ethernet Interface, Machine Edition
(or Local Station Manager) is used to initially assign an IP
address to the Ethernet Interface. Once set up, the Ethernet
Interface retains the IP addressing information. The IP
addressing information can be changed by storing a new
configuration to the CPU.
