The Operational State

The Operational State is the state of normal operation of the Ethernet Interface. This section identifies the possible symptoms of problems which may occur while the module is operating.

During normal operation of the Ethernet Interface, the MODULE OK LED is ON. The other two LEDs (ONLINE, STATUS OK) provide information about the health of the Ethernet Interface and activity on the LAN. The table below shows the LED patterns you might see and their possible meanings.

In the Operational State, no ª. . . Utilityº message follows the station ID in the NODE command. The prompt character at the local Station Manager terminal is a greater-than symbol (ª>º).

Table 6-6. Operational State

		Connected to LAN

	LED	Operating w/o	An Exception	Not Connected to LAN
		Operating w/o	An Exception
		Exceptions	has Occurred
	MODULE OK	ON	ON	ON
	ONLINE	1	1	OFF
		1	1
		ON/Blink	ON/Blink
	STATUS OK	ON	OFF2	OFF2

1.ONLINE blinking indicates this node is sending or receiving data.

2.When MODULE OK is ON and STATUS OK is OFF, it is necessary to use the Station Manager NODE, LOG, and SOSW commands to distinguish among the possible causes.

Troubleshooting When STATUS OK LED is OFF

If the Ethernet Interface is in the Operational State and the STATUS OK LED is OFF and the MODULE OK LED is ON, then the Ethernet Interface has detected an exception condition and has made an entry in the Exception Log. Each new (not repeating) log event is also sent to the PLC Fault Table, where it can be viewed using Logicmaster 90-70 Software.

The format of a log event as displayed by the Station Manager is shown below:

				Entry
Date	Time	Event	Count	1	2	3	4	5	6
dd-mmm-yyyy	hh:mm:ss.s	xx	xxxx	xx	xxxx xxxx xxxx xxxx xxxx

Date - The Date column contains the system date of the last occurrence of the logged event.

Time - The Time column contains the system time of the last occurrence of the logged event.

Event - The Event column gives the kind of event which occurred. Table 6-9 and 6-10 lists the possible values for events.
