Application — An application is represented by an event list and it’s
associated function, nodes and links.
Block Type Number — The block type number specifies one of the
28 different types of function blocks currently installed in the
function block library. You can use each type of function block as
many times as required in an execution list.
Block ID# — A block ID# is a unique number assigned to a function
block when it is entered into an execution list. The number is used to
identify each individual function block.
BRAM — This is the function block’s hard memory storage which is
battery backed up. This is often referred to as EPROM or EE storage.
EE functions and BRAM functions are synonymous.
Compiling — Compiling creates the program and data sets within
the drive. This is a background operation in the drive that involves a
series of checks before the drive accepts a downloaded function
block execution list.
Event — An event is a function block that has been assigned both a
block ID and a block type number. Both are required to enter a
function block into an execution list.
Execution List — An execution list is the list of events that will be
sent to the drive in a predetermined sequence. A maximum of 128
events are allowed in an execution list.
Input — Input refers to the data provided for a function block
operation.
Linear Parameter — A linear parameter is a fixed parameter from
1-497 that resides in the drive parameter table. These parameters
always exist and cannot be deleted from the drive, as opposed to
function blocks which can be created within the drive and
subsequently deleted from the drive.
Linking — Linking refers to the software connections between
function block nodes, or fixed drive parameters and function block
nodes.
Node or Node Parameter — A node is a dynamic, non-fixed
parameter that can be created and manipulated using the function
block program.
RAM — This is the function block’s scratch pad memory where the
application is compiled and runs. Random Access Memory is not
backed up and clears each time there is a power loss or a BRAM
initialization.
Output — The result of a function block operation.
