This manual describes the user interface of the PROFINET RT IO-Controller implementation (stack version 2.0.x.0) on the netX chip. The aim of this manual is to support the integration of devices based on the netX chip into own applications based on driver functions or direct access to the dual-port memory.
The general mechanism of data transfer, for example how to send and receive a message is independent from the protocol. These procedures are common to all devices and are described in the ‘netX DPM Interface manual’
