States of the Series 90-30 CPU364 with Embedded TCP/IP Ethernet Interface
Ethernet Interface
Initializing
(approx. 2-6 seconds)

The Ethernet Interface is initialized by
- Powering-up the PLC
- Storin g a new con figur ation to the P LC with change s for the Ethe rnet I nter face
- Pressing the Restart pushbutton
- Issuing a Station Manager RESTART, LOAD, or MAINT command
- Internal System Error occurring when Interface is Operational

Operational
Software Load Caused by
- Restart pushb utton pushe d until bottom LED tu rns O N
- Station Manager LOAD 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 by BOOTP Station Manager command
Maintenance Request Caused by
- Restart pushbutton pushed until bottom two LEDs turn ON
- Station Manager MAINT command issued
- Fatal System Error while in Operational State forced a restart
The LEDs are labeled from top to bottom as follows:
EOK
LAN
STAT
The symbols used for the LEDs are defined as follows:
= OFF
z = ON
= Slow Blink; multiple slow blinking 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
