Title: The standard for communication in the lowest field level


1
  • The standard for communication in the lowest
    field level

2
State of the Art
Information
3
State of the Art Facts not to be Changed
  • Point to point connection
  • Easy integration into fieldbus systems
  • Well covered range of sensor / actuator
    functionality
  • Well covered range of suppliers
  • Easy 3 wire connection

4
State of the Art Changes Required
  • Reduction of signal forms
  • Communication to the lowest field level
  • Combination of different signal forms
  • Smarter wiring
  • Consistent parameter storage

5
Communication to the Lowest Field Level
Information
6
5 Good Reasons for IO-Link
  • Point to point connection with standard sensor /
    actuator cable
  • Existing topologies remain stable
  • Seamless communication
  • Communication of process data and service data
    between sensors / actuators and the control unit
  • Mixed operation possible
  • Highest compatibility to standard IO
  • Fieldbus openness
  • Seamless integration into existing networks
  • Universal IO interface
  • Reduction IO-interfaces in stock

IO-LinkCombination of Functionalities
  • Function units
  • Valve cylinder combinations
  • Multi parameter sensor

11
Technical Data
  • Standard IO connection technology, point to point
    connection, unshielded, 20 m
    cable length
  • Cyclic process data transmission in 2ms
  • Simultaneous communication of process data and
    service data without influence on equidistance of
    process data
  • Mixed operation with standard sensors / actuators
    possible
  • 24 V pulse modulation, standard UART protocol

Feldbus Integration
  • Use of standard communication paths established
    in Fieldbusses
  • DPV0, DPV1, PCP,
  • Easy integration with standard engineering tools
  • GSD, GSDML, FDCML,
  • Comfortable use of even complex functionalities
    using tool-based engineering
  • FDT/DTM, TCI,

16
Time table
  • Specification available
  • IEC standardization
  • Availability of serial products
  • Integration specification for Profibus, Profinet,
    Interbus, Ethercat, AS-Interface available
