Item Description
Device No. The Device No. is the number used by the PROFINET IO
Controller DTM to reference the IO Device within the
configuration. For instance in the Diagnostic screen IO
Devices are represented by number.
Device Name The Device Name is the name the PROFINET IO Controller
will search for at startup. This name must be exactly the
same as the name entered in the IO Device.
Note that
according to the PROFINET specification only lower
case characters, dashes and numbers are allowed.
Device Type The Device Type is supplied by the Device DTM and can not
be altered.
IP Address The IP Address is issued by the PROFINET IO Controller to
the IO Device with the corresponding IP address. The IO
Device is then reachable on the network by this IP Address.
Update Rate (ms) The Update Rate is the time interval in milliseconds between
subsequent Input Data and Output Data exchanges between
the PROFINET IO Controller and the IO Device. The Update
Rate can be set per IO Device.
Watchdog Factor The Watchdog Factor is a multiplication factor on the Update
Rate to define the watchdog timeout. If an update of I/O Data
takes longer than the Watchdog Time the connection is
considered to be terminated. A new connection attempt will
be made by the PROFINET IO Controller.
