10.5.3 Device Identification and Configuration
There are several identification and configuration items available for setting
various characteristics of the Profinet device. These items are shown in Figure
19 and are explained in further detail below.
Figure 19: Profinet Device Identification and Configuration
A Profinet device’s name (station name) must be unique across the entire
Profinet network because it is used by controllers to uniquely identify Profinet
devices. The Device Name text entry box is used to configure this unique
device identifier on every drive.
The Update Time field is a configuration item which changes the frequency
with which command and status data updates take place internally in the
device. This setting is not related to the frequency with which data
communications take place on the Ethernet network. This time setting is a 32-
bit value adjustable in 1ms increments. Typically, this value should not need to
be changed from its default value of 10ms.
10.5.4 Submitting Changes
Whenever any of the Profinet configuration elements (I/O array configuration,
Device Name, etc.) have been changed, the “submit” button located in the
lower right-hand portion of the web page must be clicked in order to write these
settings to the interface card’s filesystem.
Note that because these configuration elements are read from the filesystem
only when the interface card boots up, the act of submitting configuration
changes will also reset
the interface card.
Please allow 30
seconds for the
interface card to reboot,
at which time it will then
be operating with the
recently-submitted
configuration. Refer to
Figure 20.
