Is it possible to change a cyclic OB's execution time from within LAD or STL logic? I have a 417-H CPU. |

Hello KvdM, The execution time of cyclic interrupts is a CPU parameter. You can't edit this parameter in your program. However you can see that this parameter has a blue text which means that you can edit this parameter without stopping the H system. One idea you can use is to make a scheduler in your program. You can set a cycle time of 20 msec (for instance) and based on your schedule you canchange execution time in multiple of 20 msec (e.g. 20 msec, 40 msec,60 msec and so on). Best regards. H-H |
