To cancel the read processing, press the F9 (Cancel) Key.
During read processing, “Wait” will be displayed in the lower part of the

“W: Computer → Controller Link” is used to write the data link tables from the
computer memory to nodes.
Note 1) If data link tables are written to nodes, the existing data link tables set at the
nodes will be lost. In this case, a confirmation message for overwriting will
not be displayed even if data link tables have already been set at the nodes.
Therefore, carefully check the contents of the data link tables set at the
nodes before transferring new data link tables.
When writing data to the CS1-series PC, be sure to set pin 1 of the CPU
Unit’s DIP switch to OFF.
2) When writing data link tables to a CVM1 or CV-series PC, always set the
system protect key switch on the CPU Unit to NORMAL.
3) “W: Computer → Controller Link” can also be used to delete the data link
tables for the nodes that are not participating in the data link. Always delete
unused data link tables.
4) Data link tables can be written to nodes only when the nodes are not partici-
pating in active data links or when the data links are inactive.
