Socket information reference method

As described in item 7.1.1, the station bus of an EN7 module carries information on each
of the sockets used by each user application. There are some points requiring attention
in accessing socket information.
In socket communication using instructions with the S/L module, a socket number is
acquired from Instruction USEND_T. Since this socket number is managed by the S/L
module, it must be converted into the socket ID managed by the EN7 module.
Information on each socket provided by the EN module through the station bus is
referred to on the basis of the converted socket ID.
For a detailed description of communication FB, refer to the Instruction Manual for the S
and L Controllers (6F8C0865, second and newer editions).
