Parameter

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Description

ÁÁÁÁÁÁ

Station Address

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

The station address parameter is the Medium Access Control (MAC) address of the
station being configured. The MAC address is a 12-digit hexadecimal number
which is organized as 6 bytes, each represented by a pair of hexadecimal digits.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Default Setting

- The default value is <<000000000000>> . This value instructs the

Ethernet Interface to use the factory-set, globally-unique MAC address in its EEPROM.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Modification from Default Setting

- If changed, the Ethernet Interface will store the

new Station Address in the EEPROM and use it instead of the factory default.

ÁÁÁÁÁÁ

Load Source

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

The load source field defines the load source for the GEnet LAN software.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Default Setting

- The default setting for this field is “ALT”. This means that the

Ethernet Interface module will try to obtain a load from the serial port and the
network (in that order). The software will alternate between the two load sources
until one is found.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Modification from Default Setting

- You may wish to specify the load source. The load

source may be changed to:

“LOC” (serial port) - only
“NET” (network) - only

If the load source specified is not available for the module, it will wait indefinitely for
that load source to be made available.

ÁÁÁÁÁÁ

LAN Online

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

This parameter tells the GEnet LAN Interface module whether to connect to the LAN
after initialization.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Default Setting

- The default setting is YES. This means that the module will

connect to the LAN.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Modification from Default Setting

- The default may be changed to NO. This

means that the module will not connect to the LAN.

ÁÁÁÁÁÁ

Backplane On-
line

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

This parameter tells the GEnet LAN Interface module whether or not to allow back-
plane communications.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Default Setting

- The default setting is YES. This means that the module will allow

all forms of backplane communications.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Modification from Default Setting

- The default may be changed to NO. This

means that the module will only allow diagnostics mail traffic. This setting will not
permit application data transfer with the Series 90-70 CPU.

ÁÁÁÁÁÁ

Network Load
Address

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

The multicast address to be used by the LAN Interface to load across the LAN. It is in
the same format as the Station Address.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Default Setting

- The default value is <<000000000000>> . This value instructs the

LAN Interface to use the default network load address, <<090060000000>> , as its
load address.

ÁÁÁÁÁÁ

ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ

Modification from Default Setting

- If changed the Ethernet Interface will look for a

network load from the specified multicast address. This MUST be a multicast address.
