Addressing MS/TP devices
This operation is for unconfigured MS/TP devices only. Based on the type of connection selected, use the associated procedure to auto-address all unconfigured MS/TP devices on the specified network. This operation will set only the MAC address of the devices.

One device on the network must be configured. From this configured device, the auto-address operation can be issued to other devices on the network.
All processes can take up to 3 minutes.
For these features to work, ensure that all engineered devices have the checkbox Use Auto Addressing activated.
