Socket-by-socket information covers each of the sockets used by a user application.
Note: In socket communication using FB instruction, for example of the S3 controller, a
socket number is acquired from an instruction word using USEND_T instruction.
Such socket number is managed by the controller, so that it must be converted
into a socket ID to be managed in the AN712 module. On the basis of the con-
verted socket ID, the AN712 module refers to the socket unit information avail-
able to the station bus.
