(3) Precautions
(a) Device set to "Device (PLC Side)"
Set a device range that differs from the one used for the following:
• Refresh parameters for other network modules
• Auto refresh parameters for CC-Link master/local module
• I/O numbers used for I/O modules and intelligent function modules
• Auto refresh setting for intelligent function modules
• Auto refresh using the CPU shared memory in a multiple CPU system
(b) Link refresh range
Set only link devices used in the CPU module for link refresh range. Doing so will
reduce link refresh points, resulting in a shorter link refresh time.
(c) Changing link device assignment in the "Network Configuration Settings" window
Correct the link refresh ranges of refresh parameters.
(d) Setting an extended data register (D) or extended link register (W) as a link
refresh device
Set the link refresh range properly so that it does not cross over the boundary
between the internal user device and the extended data register (D) or extended
link register (W). (Refer to the user's Manual (Function Explanation, Program
Fundamentals) for the CPU module used.)
(4) Setting example
For setting examples, refer to Chapter 11.
