No indication what the flashing is used for. So the following is legal: Let us assume you wish to use generate a pulse to flash a light for example. Then you may want to have a slow pulse and a fast pulse. Choose the one you want from the list of possibilities. Bonus.. The cycle pulse above ("flasher"), can be called in OB30 which is a time cyclic interrupt.

Library of general functions (LGF) for SIMATIC STEP 7 (TIA Portal) and SIMATIC S7-1200 / S7-1500 Regards, Towome
