Hello. The answer you have received is the right one. The memory bit you are using is a globally accessible variable (also called tag). You can create a local tag in the parameter list (see picture). STAT variables are like the global variables when it comes to "remembering" its value from one PLC scan to the next, but its access is suppose to be private. If you want to switch on / off only for one of the code blocks without the need for saving the state, you might consider adding another input. Add it in the same way as the "1" input you have now. Then you can ling the memory bit external from the block. As introductory material you could have a look at the videos supplied by Siemens: for you case now, perhaps -> Regards. |
