Accept: To approve the edit made to an online program. Rungs that have been
added, deleted, or modified must be accepted and verified before they can
be downloaded to a Processor.
BitĆindexed variable: A variable referencing a bit within an integer or double integer
variable. For example, pump.15 references bit 15 within the integer variable
"pump."
Commit: To allow the Editor to verify and download changes made to an online
program. You must accept online changes before you can commit them. You
can commit online changes immediately after you accept them or while the
program is in Test Mode.
Data Structure: Data structures contain a collection of Boolean and double integer
data and are used for the timer and counter data types.
ElementĆindexed variable: A variable referencing an element within an array variable.
For example, panel[11] references an element 11 within the array variable
"panel." An element can be a Boolean, integer, or double integer.
Global Variables: Global variables can be referenced by ladder, Control Block, or
BASIC programs in a rack. Global variables can refer to memory locations,
physical I/O locations, or network locations. Global memory variables can be
of any data type supported by the Editor. If you type in the first letter of a
variable using upper case, the default scope will be global. The names of
global variables appear in upper case.
Local Variables: Local variables are those that can only be used in the program in
which they are defined. No other programs can reference them. If you type in
the first letter of a variable name using lower case, the default scope will be
local. The names of local variables appear in lower case.
