  • Page 6: Principle Of Operation

    SIMATIC S7 controllers S7-1500 S7-1200 PROFINET/IE SIMATIC MV500 reader MV550 S The "Ident_Profile" block from the "SIMATIC Ident" library serves as the communication interface between the MV550 S optical reader and the SIMATIC S7-1500 CPU. The MV550 S optical reader is connected to the SIMATIC S7-1500 CPU directly over PROFINET IO.

  • Page 7: Initialize The Mv550 S Optical Reader

    1 Introduction 1.1.1 Initialize the MV550 S optical reader In this application example, the MV550 S optical reader is initialized with a program selection. Initialization with program selection enables: • Initialization after startup – After the self-test, the optical reader switches to processing mode with the selected program number.
