Please help, thanks.

L1.0 means bit 0 of byte 1 (beginning from 0). It is valid only as long as the block is running, otherwise it does not exist. Since you are new, you can check this thread: ALL SIMATC Useful Manuals (Good for beginners on this Forum) The info above is in #10 (S7-300 CPU 31xC and CPU 31x: Technical specifications) Hope this helps.
