In device configuration (CPU1212C) I assign MB0 as clock memory byte. I want to use m0.5 memory bit with frequncy 1Hz for an increment instruction. But,that not work. In monitoring I can't see activate state of M0.5 and, of course inc instruction isn't performed. Can someone tell me what's wrong? BR.

Whenassigning memory bits, STEP7-Basic will make suggestions for the address to be used. If you did not assign the clock bits/byte yourself, the suggestion will start with M0.0 and so on. Make shure that you donotset M0.5 or MB0elsewhere in your program.
	Always read the manuals first. Then use the "information system" also known as "help". If that does not bring you further, ask a question but... give all the details! No need to thank, no need to rate.
