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.
