Link refresh
This function automatically transfers data between the link devices of the Simple Motion module and the devices of the CPU
module.
Concept of the link refresh range (number of points)
The link refresh is performed to the area set in "Refresh Settings" under "Basic Settings" and also specified in "Network
Configuration Settings" under "Basic Settings".
Shortening the link refresh time and transmission delay time
The link refresh time and transmission delay time can be shortened by reducing the number of link refresh points to the CPU
module. The following methods can be used to reduce the number of the link refresh points.
• In "Refresh Settings" under "Basic Settings", set only the link devices used in the CPU module as the link refresh range.
(
• Directly access infrequently used link devices from the program, and remove the corresponding settings from the link
refresh range. (
