Another note.. Some PLCs allow time interrupts. These can be set to regular intervals. w |

Thank you for that link. That would sure help Sajit if he is using an S7-300 / S7-400. Those functions are also available on the S7-1200 (FW4) and S7-1500. @Sajit: Please tell us which PLC and what software are you using? w |

Dear William, my issue is still not resolved. The trigger is not the issue. My machine will create a trigger which I will use to save the time and date of when the activity was done. Then I need to add a particular no of hours to this savedtime and date to get the new date and time for again doing this activity. The same activity is repeated every half hour at different locations (72). thanks |
