Q: Why do I get 44818/tcp closed EtherNetIP-2 on my NJ V1.49 or greater
A: One reason that the port may be closed would be if Do Not Use option for the CIP message server is selected.
I found this in NJ/NX built in EIP port Manual (Section 7-3)
NJ/NX-series CPU Unit Built-in EtherNet/IP Port User's Manual
Default is USE (Section 4-7)
