Programming Example
This programming inputs a One-shot Reading Command to the PLC’s DM Area. The
V530-R2000 accesses this command and reads the data.
The read data is written to the specified words in the PLC.
1.
Set the read conditions of the V530-R2000 and display the Read Screen.
2.
Set the command to start reading DM 0100 of the PLC.
The V530-R2000 reads the code, writes the Write Flag in DM 0110, and writes the read data to DM Area
words beginning with DM 0111.
3.
Check the Write Flag in DM 0110 in the PLC.
If data has been written, the Write Flag will have changed from 0 to F.
The Write Flag will change to 0 at the first reading after turning ON the power supply, so store F as
the initial value.
