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.
