Hi All, I am now working with SIEMENS LOGO OBA8 and just wanna know some details regarding VM Mapping. 1.If I am not connected to the LOGO, can I do the VM Mapping Offline? 2.Is there any restriction for Mapping offline? Because I had seen only the variables which are not physically wired is been displayed offline, say for example Analog comparators and stuffs like that. Any help on this is highly appreciated.. Thanks, Prasanth ------------------------------------------------------------------------------------------ |

V0.0 - V0.7 = VB0 V0.0 - V1.7 = VB0 + VB1 = VW0 V0.0 - V3.7 = VB0 + VB1 + VB2 + VB3 = VW0 + VW2 = VD0 The addressing is byte-oriented. With a word (VW) or double word (VD), the address (e.g. VD4) is the specification of the first byte (with VD4 it is VB4). The address of a V bit (Vx.y) is made up of the byte address x and the bit address y. V0.4 = bit 4 in byte 0.
