(1) Backup of CC-Link related parameters
CC-Link related parameters are the network parameters to be written from GX Developer. These
parameters are stored in the ladder program area within NC, which is a different area than that of
regular NC parameters.
In order to store these network parameters externally, the data must be output and saved with the
following methods.
With GX Developer:
(1) Select "PC" menu.
(2) Select "read" menu.
(3) Read the selected parameter and store them as a file on PC.
(Note) Select "write" menu and follow the same procedures to write
parameters.
With NC:
(1) Select the data output screen.
(2) Output the PLC program area.
(Output by setting #(99)DATA( ALL3).)
(Note) Select the data input screen to write parameters.
(2) Replacing the CC-Link card
The CC-Link parameters are stored in the NC. Therefore, if the CC-Link card mounted on the NC
must be replaced due to malfunction, etc., the parameters are not necessary to be written again
with GX Developer, etc.
(3) Precautions when inputting CC-Link related parameters
When inputting CC-Link related parameters with GX Developer, NC ladder program area must
correspond to the CC-Link related parameters.
In order to correspond to the CC-Link related parameters, NC ladder program area must be
formatted with the NC system incorporating CC-Link function before writing the ladder into the NC
(only once at the initial time). Select the DX Developer "PC memory format" menu when formatting
the NC ladder program area. Make sure that the CC-Link card is mounted when formatting.
(Note 1) When outputting CC-Link related parameters or making a PLC program cassette, make
sure that the NC ladder program area corresponds to the CC-Link related parameters.
(Note 2) Having formatted the ladder program area, make sure to write the ladder before turning
OFF the power. If the power was turned OFF without writing the ladder, carry out
formatting again.
