 After that, you can create registers, using for them the standard notation of memory area addresses in Siemens PLCs - QB0.0, VW0, etc. For more information, see here.  After that, you can create registers, using for them the standard notation of memory area addresses in Siemens PLCs - QB0.0, VW0, etc. For more information, see here. 
  
-**Note** - although WebHMI correctly recognizes addresses with the data type included in them (for example, IW0 in the notation indicates a Word type register from Inputs memory), but WebHMI will decide what data length to read from ther register setting (IW0 will serve only as base address)I.e. the  +<WRAP center round info 60%>
