CHAPTER10 FUNCTIONS AND PROGRAMMING

This chapter explains the bus interface functions and MELSEC data link functions supplied
with by SW PVC-CCPU.
When utilizing the program examples introduced in this chapter for an actual system, be
sure to verify that no problem will arise in the target system control.

10.1 Outline of Functions

The functions supplied with SW PVC-CCPU must be used to access and control
programmable controller CPUs and each module on the user program.
(1) The following indicates the applications of the bus interface functions.
The above applications are shown in the following conceptual illustration.

- 1 10.1 Outline of Functions
1) I/O control of I/O modules controlled by the C Controller module.
2) Access to the intelligent function module buffer memory controlled by the C
Controller module.
(The X/Y access, buffer memory access, and wait for interrupt event from
intelligent function module/QI60 are possible.)
3) Linkage between the C Controller module and the programmable controller
CPU within the same system.
4) Message transfer between the C Controller module (other station),
programmable controller CPU (other station), and a personal computer with
MELSECNET/H board, via a MELSECNET/H module controlled by the C
Controller module.
5) Access to the link device of the MELSECNET/H module (self station).
6) Start of a routine from user watchdog timer error interrupt.
7) Remote RUN/STOP/PAUSE control of the C Controller module.
8) Event log registration to the event history file.
9) Mounting and discounting of the CompactFlash card.
10)Shutdown of the standard ROM.
11)Setting and reading of the clock data.
12)Data writing to or reading from the battery-backed-up RAM.
