WATCHDOG CYCLE Menu

Description	The duration of a program cycle depends on its length and complexity: In particular,
	the type and number of inputs-outputs and the number of extensions.

The program is executed periodically at regular time intervals. This time interval is called the cycle time.

The program will only execute completely if the cycle time is greater than the program execution time.

The cycle period is configurable in the : CONFIGURATION → CYCLE WATCHDOG menu. This period may be set from 6 to 90 milliseconds in 2-

millisecond steps.

The default value of the cycle period is 10 milliseconds.

Illustration:
C Y C L E = 0 5 x 0 2 m S
W A T C H D O G I N A C T I V E
-	+
	Menu / OK

Note: Make sure that:

zInput variations that are too rapid are not masked by cycle time that is too slow,

zThe speed of output variations is compatibles with system commands.

If the duration of the execution cycle of the program and the embedded software functions exceeds the cycle time value selected by the programmer, the WATCHDOG can be used to operate a specific action.

Note: In certain dialog phases, the cycle times are increased by the communication times between the PC and the smart relay. No guarantee can be made concerning the real cycle times during this operating mode. The WATCHDOG is always inhibited in this smart relay operating mode.

Note: To return to the main menu from the CONFIGURATION menu, use the navigation key .
