 It is possible to connect to the Siemens 1200 series controllers using the ISO-on-TCP protocol. To do this, several additional settings must be made in the controller configuration. To activate the S7 Communication operation mode in TIA Portal, the PLC must be configured correctly.

 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

+Please note that WebHMI will recognize the data type for the S7 register not from the register address expression of MW, MB or MD, but from the register configuration, i.e. what data type (Byte, Word ..) is chosen for the register
