Changing the AMS NetID

This work step shows how you can change the AMS NetID of the industrial PC. Note that in doing so you will also change the address of the industrial PC in the TwinCAT network. The AMS NetID consists of 6 bytes and is represented in dot notation and in the hexadecimal system.

Requirements:

Access rights to the file TcRegistry.xml

Proceed as follows:

1. Stop the TcSystemService with the command doas service TcSystemService stop

2. Enter the command doas ee /usr/local/etc/TwinCAT/3.1/TcRegistry.xml in the console.
The file TcRegistry.xml opens.

<Value Name="CurrentVersion" Type="SZ">3.1</Value>
<Key Name="System">
      <Value Name="RunAsDevice" Type="DW">1</Value>
      <Value Name="AmsNetId" Type="BIN">053B151A0101</Value>
</Key>

3. Change the AMS NetID under the entry

<Value Name="AmsNetId" Type="BIN">053B151A0101</Value>.

The entry 053B151A0101 corresponds to the following AMS NetID: 5.59.21.26.1.1

4. Press [Esc] and save the changes.

You have successfully changed the AMS NetID. Restart the TcSystemService with the command doas service TcSystemService start
