Under "link refresh settings", you must check and set the information of the final slave station connected to the CC-Link
master/local module.
For more information, refer to " MELSEC iQ-R CC-Link System Master/Local Module User's Manual (Application) ".
In the following example, this is set by changing [Device Assignment Method] to [Points/Start].
Link side settings
The number of link points must be set so that it matches all the slave station information.
The following table show the number of link points for SC-HG1-C. Check the number of link points as needed.
The first character on the link side should be 0.
Figure 1.5.3-8 shows an example where only one unit of SC-HG1-C is connected and used in CC-Link mode1.
CPU side settings
Specify the bit and word devices for the refresh target device name.
Also, the start may be arbitrarily set. When specifying the same device, take care to avoid overlapping from the start to end.
The "device names" and "start" you specify here relate to the global label configuration. For more information, see "1.4.3
Identifying the starting device".
