To execute a cyclic transfer using the FL-net module (JW-20FL5/20FLT and JW-50FL) and FL-net
board (Z-336J), the parameters in the common memory areas (area 1 and 2) must be set.

Capacity

- Nodes used to execute a cyclic transfer must have 8.5 K words of memory available for the

common memory area.

- Areas that can be allocated as the common memory area

Page 8-4 to 8-6.

- Notes on the common memory areas
