Viewing / Editing IO-Device Properties

In addition to the parameter configuration described on the previous pages, all IO-Devices (PNS modules and
third-party devices) have other configurable properties. These properties are displayed in the Machine Edition
Inspector pane when the device is selected in the Navigator.
In the Inspector, properties that are not grayed-out can be used as is or edited as appropriate.
Device Number: a number automatically assigned to the device in the configuration.
Update Rate: The period between PROFINET cyclic data transfers between an IO-Controller and an IO-Device.
Defaults to 32ms for RX3i and VersaMax PNS modules, and to 128ms for third-party devices. To change the
update period of the PROFINET production cycle for the IO-Device, use the drop-down list to select 1, 2, 4, 8, 16,
32, 64, 128, 256, or 512ms:
Note: Note that shorter update periods place higher processing loads on the associated PROFINET
Controller. Refer to Section 3.1.1.2, PROFINET Controller Loading Limits. A PNC001 module can handle
heavier loads than an equivalent embedded PROFINET Controller.
