DEVICE EXPLANATION
(b) Use the same file name as the program
POINT
This setting should be selected when the file registers having the same file name
as the sequence program are to be used.
1) Operation performed when program is changed
If the program is changed, the file registers are automatically changed to
conform to the new program name.
There are also cases where it is convenient to use the file registers as local
devices which can only be used with the program currently being executed.
2) Setting of file register points
Choose [Online] [Write to PLC] on GX Developer to set the number of
available file register points.
Example
When file registers (A to C) having the same name as the programs (A to C) are to be used,
operation is as shown below.
At program A is execution
At program B is execution
At program C is execution
Program A execution
Program B execution
Program C execution
