Assignment of PROFINET name to a PROFINET Device

For an initial configuration of a PROFINET Device or when the EL663x-0010 is delivered, it does not have a PROFINET name. An empty string is transferred when the devices are configured. There are several ways to assign a name to an EL663x-0010:

1. Assignment via the PROFINET Controller

In this case, the PROFINET Controller assigns the name of the device. Please contact the PROFINET Controller manufacturer for more information.

2. Assignment via the EtherCAT Master, only with the EL663x-0010

An assignment via the controller is then no longer possible.

To do this, activate the checkbox get PN-Station name from ECAT. The name used in the Manager tree is then used. In this example el663x-test-name.

3. Assignment via a link to the PLC program

An assignment via the controller is then no longer possible.

This is comparable with the DIP switches in the BK9103 and can be carried out via a PLC task. For activation, Generate Station Name from Control must be activated.

For clarification, 000 will be appended to the previous tree name (default: tcpniodevice). 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 CtrlWORD must be linked to a task.

It is subsequently necessary to restart TwinCAT. If, for example, the linked Ctrl WORD is now given a value of 123 from the task, its previous station name changes, e.g. from tcpniodevice to tcpniodevice123. The current tree name is still tcpniodevice000.

4. Assignment via TwinCAT

An assignment via the controller is then no longer possible.

To do this, activate the checkbox Get Station Name from Tree. The PROFINET name that the device has in the TwinCAT tree is then used.

5. Automatic device startup via topology specification is supported.
