When go online and scan the network with proworx nxt software, a node is detected but with DIM awareness. how to solve this and what is the root cause

[Crossbow 295]

Dim Awareness means the PLC is not configured and does not have a program. Probably the battery went dead and the unit was powered off. Download a new program and it will go away. You'll probably get at least a couple of warnings about dim awareness before it allows the download, but it should go through fine.
