BLINK

Provided by util.lib.

The function block BLINK generates a pulsating signal. The input consists of ENABLE of the type BOOL, as well as TIMELOW and TIMEHIGH of the type TIME. The output OUT is of the type BOOL.

If ENABLE is set to TRUE, BLINK begins to set the output for the time period TIMEHIGH to TRUE and afterwards to set it for the time period TIMELOW to FALSE.

When ENABLE is reset to FALSE, output OUT will not be changed, i.e. no further pulse will be generated. If you explicitly also want to get OUT FALSE when ENABLE is reset to FALSE, you might use “OUT AND ENABLE” (i.e. adding an AND box with parameter ENABLE) at the output.
