Creating Data Files
If your application requires a lot of data manipulation or use of sequencers,
you may want to create the data files and enter the data prior to developing
the ladder diagram. Also, if you are using indexed addressing in your SLC
5/02 program, you need to create the data file elements that the instructions
may index into.
You cannot create additional elements in the output file (file 0), input file
(file 1), or status file (file 2). These files can only be created through the
processor and I/O configuration.
Data is created by entering the highest numbered element you want to be
included. For example if they have not already been created, entering
element N7:12 (default integer file 7) creates element N7:12 and all lower
numbered elements down to N7:0.
