50 Function Files
Overview
Function Files are one of the three primary file structures within the
MicroLogix 1100 controller (Program Files and Data Files are the others).
Function Files provide an efficient and logical interface to controller
resources. Controller resources are resident (permanent) features such as
the Real-Time Clock and High-Speed Counter. The features are available
to the control program through either instructions that are dedicated to a
specific function file, or via standard instructions such as MOV and ADD.
The Function File types are:
