Fig. 22: Tree name in the TwinCAT tree
Tree name
This tree name no longer corresponds to the PROFINET station name! The Ctrl WORD of the
PROFINET protocol is used to help assign a name. This means that the number that is entered
(range of values 0 - 255) is appended to the existing station name. In addition, the Ctrl WORD must
be linked to a task. It is subsequently necessary to restart TwinCAT. If, e.g., the task now specifies
a value of 11 for the linked Ctrl WORD, its previous station name will change from, for example,
"tcpniodevice" to "tcpniodevice011". The current tree name remains "tcpniodevice000".
The current station names and the IP configuration used can be checked via the "PROFINET diagnosis" tab.
4.2 Diagnostics
The actual PROFINET name is displayed on the Diagnostics tab. The IP configuration is specified when the
master boots up, and has the values that are assigned by the master. The "Module Difference" field is
displayed if the specified configuration is not the same as the actual configuration. The field should be empty
if there is no error.
