SLC File Types
This section contains information specific to the SLC and MicroLogix processor
based family when used with the PCCC command set. The SLC and MicroLogix
processor commands support a file type field entered as a single character to
denote the data table to interface with in the command. The following table
defines the relationship of the file types accepted by the Gateway and the SLC
file types.

The File Type Command Code is the ASCII character code value of the File Type
letter. This is the value to enter into the "File Type" parameter of the PCCC
Command configurations in the data tables in the ladder logic.
Additionally, the SLC specific functions (502, 510 and 511) support a sub-
element field. This field selects a sub-element field in a complex data table. For
example, to obtain the current accumulated value for a counter or timer, the sub-
element field should be set to 2.
