Chapter 7 Application Interface
The base address of the station bus address varies depending on the slot
where the TN8 module is installed. The following table shows the
starting word addresses of the information by socket when the TN8
module 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 TN8 module. 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 TN8 module. Based on the converted socket ID, the information
by socket is referred to that is expanded on the station bus of the TN8
For detailed explanation of the communication FB, refer to "Unified
Controller nv series/Integrated Controller V series Command Manual"
