Schneider Optics Modicon Quantum Ethernet Application LED, Reading and Clearing the Error Log

Page 67

Maintenance

If the Coll LED is flashing, the module is reporting collisions on the Ethernet network. While such collisions are normal, the frequency of the flashes is an indication of the volume of traffic on the network. The flashes may be so frequent that the LED appears to be shining steadily. Heavy traffic will slow communications. If response time is important to your application, you should consider segmenting your network to reduce the frequency of collisions.

6.1.8Application LED

If the module crashes, it will note the reason in a log. If the module is able to recover, the Appl LED will light, indicating that an entry has been made in the error log. To learn how to read and clear the error log, refer to the section below.

6.1.9Reading and Clearing the Error Log

If the Appl indicator is lit, entries have been made in the error log. The log may hold up to 1023 entries. If the error log is full, the Fault indicator will remain on and the module will be unable to recover until the log is cleared.

You may read the error log while the controller is running or stopped, using the ER- RLOG utility. However, if you plan to clear the error log, you must stop the controller first. During the program, ERRLOG will ask you whether you want to stop the con- troller. If you respond yes, it will stop and restart the controller for you.

CAUTION

PROCESS INTERRUPTION

Do not stop the controller unless it is safe to stop the operations it is controlling. When a controller is stopped, all operations under its control will also stop.

Failure to observe this precaution can result in injury or equipment damage.

To read the error log, at the DOS prompt in the appropriate directory, type:

ERRLOG <routing path> <slot> [/d] [/sxx] [/ny]

where <routing path> is the Modbus Plus address of the Quantum PLC <slot> is the slot number of the Ethernet web embedded server module. [/d] is optional, to enable debug messages. Default is no debug.

[/sxx] is optional and specifies the software interrupt to use, xx in hexadecimal. The default is 5c.

[/ny] is optional and specifies the Modbus Plus adapter number to use, y.
