WATCHDOG Configuration

The WATCHDOG can perform the following different actions:

zINACTIVE: normal operating mode,

zALARM: A warning state is set and the warning number corresponding to Cycle time overrun is accessible in the FAULT menu,

zERROR: the program stops (STOP mode) and the error number corresponding

to: Cycle time overrun is accessible in the FAULT menu.

The cycle time may be set from 6 to 90 milliseconds in 2-millisecond steps.

To adjust this period, adjust the step multiplier factor by 2 milliseconds using the + and - keys of the contextual menu. This factor is between 3 and 45.

C Y C L E = 0 5 x 0 2 m S

The multiplier factor is adjusted depending on the shortest sampling period of the inputs.

Procedure:

Step Action

1Configure the CYCLE parameter using the + and - keys of the contextual menu.

2Confirm the entry using one of the keys: or .

Result: The CYCLE parameter is confirmed and the WATCHDOG parameter is selected (it flashes).

3Configure the WATCHDOG parameter using the + and - keys of the contextual menu.

4Confirm your changes by pressing the Menu/OK key. Result: The display returns to the MAIN menu.
