Referring To Information By Socket - Toshiba Vm Series Instruction Manual

Chapter 7 Application Interface
The base address of the station bus address varies depending on the slot
where the TNB is installed. The following table shows the starting word
addresses of the information by socket when the TNB 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 TNB. 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 TNB. Based
on the converted socket ID, the information by socket is referred to that is
expanded on the station bus of the TNB.
For detailed explanation of the communication FB, refer to "Unified Controller
/Integrated Controller Command Manual" (6F8C1226).
