(d) Automatic data transfer between link devices and the devices of a CPU module (Link
refresh)
Automatic transfer is available between link devices of the CC-Link IE Controller Network module and devices
of a CPU module. (
For the Universal model QCPU other than the Q00UJCPU, the extended link register (W) is useful for
transferring link register (LW) data that exceeds the link register (W) capacity (8K points).
*1 Models other than the Universal model QCPU do not have the extended link register (W).
Use a file register instead.
[When using the extended link register as the transfer target CPU-side device]
MOV D0
MOV W8200
Programming is easy because both
device numbers are hexadecimal.
[When using a file register as the transfer target CPU-side device]
MOV D0
MOV ZR33280
Attention must be paid for programming
because decimal and hexadecimal device
numbers are used.
(e) Direct access to link devices
With a sequence program, data can be directly read from or written to CC-Link IE Controller Network module's
link devices (LB/LW/LX/LY/SB/SW). (
For the Universal model QCPU, all of the link devices can be specified.
*2 For models other than the Universal model QCPU, the area of address LB/LW4000 or higher cannot be specified.
(f) Assurance of cyclic transmission punctuality
Cyclic transmission punctuality is assured even during transient transmission.
Applications can be created without the need to consider link scan time fluctuation. (
