6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
6.1 Information necessary for program creation
6.1.1 When ACPU/QCPU (A mode) is used
[1] System used in this chapter
An example of the sequence program explained in this chapter for use of the
ACPU/QCPU (A mode) is described for the following system.
For the sequence program for the entire CC-Link system, refer to the CC-Link Master
Module User's Manual; for details on the dedicated instructions, refer to the Type
AnSHCPU/AnACPU/AnUCPU/QCPU-A (A Mode) Programming Manual (Dedicated
Instructions).
When applying any of the program examples introduced in this chapter to the actual
system, verify the applicability and confirm that no problems will occur in the system
control.
(1) System configuration for program example
PLC CPU
Master module (X0 to X1F/Y0 to Y1F)
D75P2 (Station No. 1)
(2) Relation of PLC CPU, master module and D75P2
The contents of RXn0 to RX(n+7)F are read to X100 to X17F, and the contents
of RYn0 to RY(n+7)F are written into Y100 to Y17F and used.
