Link refresh
This function automatically transfers data between the devices of the RJ71GN11-T2 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".
Shortening the transmission delay time
The transmission delay time can be shortened by reducing the number of link refresh points and shortening a communication
cycle interval. (
Page 293 Communication cycle intervals)
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 frequently used in the CPU module as the link refresh
range. (
Page 99 Refresh Settings)
• Remove infrequently used link devices in the CPU module from the link refresh range, and directly read or write the
corresponding data from the program by direct access. (
Page 31 Direct access to link devices)
Link refresh is performed in END processing of the sequence scan of the CPU module.
