module.

Concept of the link refresh range (number of points)

The link refresh is performed in the range 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 286 Communication cycle intervals)

To reduce the number of link refresh points, in "Refresh Settings" under "Basic Settings", set only the link devices used in the

FX5 CPU module as the link refresh range. ( Page 133 Refresh settings)

Link refresh is performed in END processing of the sequence scan of the FX5 CPU module.
