Since I don't know your LOGO! programs and your HMI project, I can only guess. And I suspect an overlap in the VM storage area. The memory addressing in the VM memory is byte-oriented. The following applies to bits: Byte address. Bit address. V0.0 = Byte0.Bit0 The following applies to bytes: A byte is made up of 8 consecutive bits. Byte address. e.g. VB0. VB0 are also the bits V0.0 - V0.7. The following applies to Words: A word is made up of two consecutive bytes. The left byte is given as the start address. VW0 = VB0 and VB1 = V0.0 - V1.7. The following applies to DWords: A DWord consists of four consecutive bytes. The left byte is given as the start address. VD0 = VW0 and VW2 = VB0 - VB3 = V0.0 - V3.7.
