Chapter 7 Application Interface
The base address of the station bus address varies depending on the slot where
the JTNI is installed. The following table shows the starting word addresses of
the information by socket when the JTNI is installed to different slots.

7.1.2 Referring to information by socket
As described in "7.1.1 Configuration of information by single Ethernet socket,"
information by socket used by each of the user applications is expanded on the
station bus of the JTNI. There are some considerations when accessing the
information.
When socket communication is performed using an instruction word by the
controller, the socket number is obtained from the instruction word using the
USEND_N command. The socket number is managed by the controller. The
socket number is once converted to a socket ID managed by the JTNI. Based
on the converted socket ID, the information by socket is referred to that is
expanded on the station bus of the JTNI.
For detailed explanation of the communication FB, refer to "Unified Controller
nv series/Integrated Controller V series Command Manual" (6F8C1226).
