8 Configure the Watchdog

• Select the time period

• Select the COM port

Note 1: If you followed the instructions in Step 1 of this

procedure, you set the Watchdog timer to 30 seconds.

Therefore, you must fill in a time period that is significantly

lower than this value, for example, 8 seconds.

Note 2: After selecting the COM port, keep in mind that other

Modules use COM ports as well, such as eCAP, eESPA, eIO.

9 Verify correct operation.

To test the operation of the Watchdog, set the time in the

eKERNEL_SITE table to a higher value (for example, 40

seconds). As a result, the signal does not arrive within 30

seconds, the Watchdog timer expires, and the alarm relay

contacts are closed. After you finish testing, remember to set the

time value in the eKERNEL_SITE table back to its original value

(for example, 10 seconds).
