Translations:Siemens S7 Communication/1/en

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:

PLC address - This is the IP address of the controller or the communication module.

TSAP - This is the device address in the COTP protocol. It is indicated in hexadecimal format. The high byte indicates the access type (default is 03). The low byte consists of two values ​​of Rack (default is 0) and Slot (default is 1). See the documentation for the controller for more details. WebHMI uses local TSAP number = 1000.
