This chapter explains an overview of the functions included in the MELSEC Data Link
Library.
The functions provided by the MELSEC Data Link Library are used when creating a
user program that communicates with a programmable controller CPU. With these
functions, the user can perform communications without worrying about the hardware
type of the destination device or the communication protocol.
The following table lists the functions that are provided by the MELSEC Data Link
Library that comes with the utility software.
