Ethernet Interface



Initializing 1



 (approx.10-20 seconds)

1The Ethernet Interface is initialized by

-Powering-up the PLC

-Storing a new configuration to the PLC with changes for the Ethernet Interface

-Pressing the Restart pushbutton

-Issuing a Station ManagerRESTART,LOAD, or MAINT command

-Internal System Error occurring when Interface is Operational

-Full support for client and server capability

-Uses user defined Advanced Parameters

Software Load Caused by

-Restart pushbutton pushed until bottom LED turns ON

-Station ManagerLOAD command issued

-Detection of corrupt software

Waiting for IP Address Caused by

-Not configuring Interface using configuration software

-Configuring Interface with IP address = 0.0.0.0

-New CPU with no configuration

-CPU failure to communicate with Interface

Continue to Maintenance or Operational Caused by

-IP address received from network BOOTP server

-IP address entered byBOOTP Station Manager command

Maintenance Request Caused by

-Restart pushbutton pushed until bottom two LEDs turn ON

-Station ManagerMAINT command issued

-Fatal System Error while in Operational State forced a restart

Symbols

The LEDs are labeled from top to bottom as follows:

MODULE OK

LAN ONLINE SERIAL ACTIVE STATUS

The symbols used for the LEDs are defined as follows:

= OFF

z= ON

œ= Slow Blink; multiple slow blining LEDs blink in unison

= Fast Blink

= Traffic (blinks when there is traffic on the line) The process symbols are defined as follows:

= Temporary condition; requires no intervention

= Decision point during power-up

= Interface State; normally the Interface remains in a State unless there is user intervention
