Procedure for Writing Program to CPU Module
AppendicesIndex
• Although writing is also allowed in the "refresh range" portion of the link
device range (specified by refresh parameters), the link module's link device
data will be rewritten when a refresh operation occurs.
When writing by link direct device, the same data should also be written to the
CPU module related devices designated by refresh parameter.
[Refresh parameter settings]
• Network No. : 1
• CPU module (W0 to 3F) Network module (LW0 to 3F)
• When data is written to another station's writing range using a link direct
device, the data which is received from that station will replace the written
data.

"100" is written to network module
LW1 when a refresh occurs.
"100" is written to network
module LW1 when the MOV
instruction is executed.
