Chapter 24
Function Reference
Object and Function Block Basics
This chapter provides information on using each of the EZ LADDER Toolkit function blocks and objects. For
each object or function, the symbol diagram, information on the inputs and outputs and a description of the
function or block operation is provided. When applicable, truth tables, timing diagrams or other functions
details are provided.
This information is to provide basic practices of how each function or object works and is not intended to
provide complete applications or uses.
As this chapter is a reference, providing function block and object details on ALL functions available
in the EZ LADDER Toolkit, the presence of a function does not guarantee availability of the function on all
hardware targets.
Availability of functions and objects is determined by the hardware target that is configured for the ladder
diagram projects. Some functions and objects are not available on some targets. Refer to the actual hardware target’s data sheet / manual or Chapter 22 - Hardware Targets for a list of supported functions and
objects based on target selection.
It is important to formulate which function blocks may be used in a ladder diagram project and then
verify and select the target that supports the desired features and function blocks.
All objects and function blocks described in this chapter are organized in alphabetical order.
