Data Files
Data files contain the data associated with the program files. Each processor file
can contain up to 256 data files. These files are organized by the type of data they
contain. Each piece of data in each of these files has an address associated with it
that identifies it for use in the program file. For example, an input point has an
address that represents its location in the input data file. Likewise, a timer in the
timer data file has an address associated with it that allows you to represent it in the
program file.
The first 9 data files (0 - 8) have default types. You designate the remainder of the
files (9 - 255). The default types are:
•
File 0 Ć Output Data
This file stores the status of the output terminals for the controller.
•
File 1 Ć Input Data
This file stores the status of the input terminals for the controller.
•
File 2 Ć Status Data
This file stores controller operation information.
•
Files 3 Ć 7
These files are pre-defined as Bit, Timers, Counters, Control, and Integer data
storage, respectively.
•
File 8 Ć Float Data
This file is used by SLC 5/03
t OS301, OS302 processors and SLC 5/04t
OS400, OS401 processors for Float data storage.
•
Files 9 Ć 255
These files are user-defined as Bit, Timer, Counters, Control, Integer, Float,
String, and ASCII data storage.
Most of your work with data files will be in files 0 and 1, the output and input files.
Refer to appendix A for an example of the Timer data file.
