States of the Series 90-70 CMM742 TCP/IP Ethernet Interface
Ethernet Interface
Initializing
(approx.10-20 seconds)



The 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 Manager
RESTART, LOAD, or MAINT command
- Internal System Error occurring when Interface is Operational

Error?
Operational
Software Load Caused by
- Restart pushbutton pushed until bottom LED turns ON
- 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:
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
