-Since version 1.7.0.3180 WebHMI supports work with Siemens S7 controllers via S7 Communication protocol over Ethernet (Profinet interface on the controller). It makes possible for WebHMI to work with PLCs such as Siemens S7-300, S7-400, S7-1200, S7-1500 and others that support this protocol. To configure the connection, you must define the following parameters in the controller configuration:

-Note that although WebHMI correctly recognizes addresses with the data size included in them (for example, IW0 in the notation Siemens stands for a Word type register), but the data size from the address itself is ignored and instead the data size specified in the WebHMI project settings of this register is used. I.e. the address is used exclusively as an base address and in fact the three addresses IW0, IB0, ID0 are equivalent to the record I0.

 Connecting WEBHMI to Siemens controllers is possible simultaneously with other devices on the same network (HMI panels, other controllers), because the controllers support several connections, depending on the type:
