Program Example for Preset Value Change
A preset value is changed with external data transfer switches in the following
example.
1,2,3...
1.
Prepare an area of the source storing the transfer data.
Set as shown in the following diagram because the unit number is 0, the
PC data area is the DM, and the number of transfer data blocks is 6.
To transfer more than six transfer data blocks, store them in a different ar-
ea, and move three data blocks to the DM area from DM 0900 to transfer
each time. A total of six blocks of transfer data can be transferred at a time.
2.
Store the counter preset value data to be used in a DM area that is not
used by the Special I/O Unit.
The words must be from DM 0900 on.
