CHAPTER 10 PROGRAMMING USING MELSEC DATA LINK
When applying program examples introduced in this chapter into actual systems, fully
examine the applicability, and confirm that they do not cause system control problems.
10.1
Outline of MELSEC Data Link Functions
To access and control a programmable controller CPU and each module in a user
program, the functions provided by SW3PVC-CCPU must be used.
(1) The following indicates features of bus interface functions.
FUNCTIONS
1) Access to the programmable controller CPU that is in the same system as the
C Controller module.
2) Access to the programmable controller on another station via CC-Link
module(s) controlled by the C Controller module.
3) Access to the programmable controller on another station via CC-Link
module(s) or MELSECNET/H module(s) controlled by the C Controller module.
4) Message exchange with the following modules or personal computers via CC-
Link IE Controller Network module(s) or MELSECNET/H module(s) controlled
by the C Controller module.
• C Controller module (another station)
• Programmable controller (another station)
• Personal computer equipped with MELSECNET/H board (only via
MELSECNET/H module(s))
