1.2 Status LEDs
1.3 Configuration Switches
The configuration switches are used to set the PROFIBUS node address. Normally, 
these switches are covered by a plastic hatch. Note that the node address cannot be 
changed during runtime, i.e. the gateway requires a reset for changes to have effect.
The configuration is done using two rotary switches as follows:
Node Address = (Switch B x 10) + (Switch A x 1)
Note: When removing the hatch, avoid touching the circuit boards and components. 
If tools are used when opening the hatch, be cautious.
Example:
If the node address should be 42, set switch A to “2” 
and switch B to “4”.
