1.3.4 CC-Link Ver. 1.10
The conventional CC-Link products, whose inter-station cable lengths have equally
been changed to 20cm (7.87 inch) or more to improve the inter-station cable length
restriction, are defined as CC-Link Ver. 1.10. In comparison, the conventional products
are defined as CC-Link Ver. 1.00.
Refer to the CC-Link Master Module Manual for the maximum overall cable lengths and
inter-station cable lengths of CC-Link Ver. 1.00 and Ver. 1.10.

1.3.5 Communication with remote devices
(
1
)
When the CPU has automatic refresh function (example: QnA series
CPU)
Through communication with the corresponding devices using sequence ladder
logic, data is automatically transferred to/from the refresh buffer of the master
station at the execution of the END instruction to perform communication with the
remote devices.
(
2
)
When the CPU does not have automatic refresh function (example:
AnA series CPU)
Data is transferred to/from the refresh buffer of the master station directly by
sequence ladder logic to perform communication with the remote devices.
