10-7 Transferring and Saving Data
Overview
• Reading and writing data is carried out according to the number of trans-
fer words, the transfer source area, the transfer source word, and the
transfer destination address set in the operating data area.
• This operation can also be used for reading data from a PCU to which
data has already been transferred, and for backing the data up or copying
it to another PCU.
Operation Example
X-axis operating data from an NC213 PCU which has already transferred the
operating data for two axes is read into the DM Area. The operating data set
for the DM Area is written to an NC113 PCU and saved. By combining these
two operations, the NC213’s X-axis data can be copied to the NC113.
READ DATA
1,2,3... 1. Mount the NC213 (Unit #0) to the Programmable Controller’s CPU Rack.
Make sure that the data and parameters for both the X and Y axes needed
for the operation of the NC213 (Unit #0) are all transferred.
2. When the operation start switch is turned ON, the parameters and data for
the X axis of the NC213 are read into D03000 through D03799 at the PLC.
3. When work bit W03010 turns ON the read operation is completed.
WRITE DATA and SAVE DATA
1,2,3... 1. Mount the NC113 (Unit #2) to the Programmable Controller’s CPU Rack.
Set the parameters and data for the X axis of the NC113 in D03000
through D03799 of the PLC.
2. When the operation start switch is turned ON, the parameters and data in
D03000 through D03799 are written to the NC113 and then saved.
3. When work bit W03014 turns ON, the WRITE DATA and SAVE DATA oper-
ations are completed.
