Also, from the controller settings in the TIA portal project, it is necessary to take its IP address and TSAP (this is the device address in the COTP protocol. It is indicated in hexadecimal format.The high byte denotes the access type (by default 03) .The low byte consists of two Rack values (by default 0) and Slot (default 1). See Siemens documentation for controllers for more details). | Also, from the controller settings in the TIA portal project, it is necessary to take its IP address and TSAP (this is the device address in the COTP protocol.
