It fills [Length] elements of the [Destination] with the [Source] value.

In this case, it writes a 0 to all members of the Lube_Mode UDT.

See also the [IMPORTANT] and [Tips] notes about using FLL to write to a structure (UDT).

Hello. That depends on what is configured in the PLC program. For example, I used the device name that you provide in your screenshot for a Rockwell EtherNet/IP armour block, and I can see the controller tags addressed by that device name. But it could be a ControlNet device or a DeviceNet device or a local module connected in the logix backplane bus. Thus you have to verify the Logix program. Hope this helps.
