MotionSuite™ Series Machine Controller Software Manual Chapter 8: Ladder Programming
8-8
Input a symbol name of 8 16-bit characters or less. This symbol is displayed
during operand input in the program window. The first character in a symbol
name cannot be a number, -, or _. Symbols beginning with the character $ are
either symbols defined in MotionWorks™, or are called automatic symbols as
they are automatically allocated by MotionWorks™. Automatic Symbols are
displayed as follows:
$AUTOxxx (xxx is a number starting from 001)
Ladder and function programs cannot be saved when there are automatic sym-
bols remaining. Change automatic symbols to another symbol name.
2. Register Number
Input the register number defining the symbol. Input a symbol without inputting
a register number during operand input in the program window to display the
corresponding register number.
3. Size
Input the amount of data to be obtained by the symbol. The default setting is 1.
The data input here is displayed in hexadecimal form. Attach an “H” to the start
of a number when inputting hexadecimals. This data is enabled during autonum-
bering of a register defined to a symbol. For example, when autonumbering is
executed at size 1 for MW00001, the next symbol becomes MW00002, and a
one word size is allocated from MW00001 on. If autonumbering is executed at
size 2 for MW00001, the next symbol becomes MW00003, and a two word size
is allocated from MW00001 on. See “Symbol Autonumbering” in this item for
how to autonumber.
4. Range
Input the symbol range.
Auto: Shows the symbols to be autonumbered (when allocated by
MotionWorks™)
MTBL: Shows the symbols subject to upper level linkage. It is possible
to execute upper level linkage using the upper level linkage
function, and set the same symbol definition data for each type
of scan.
User: Shows user-defined symbols (if the register numbers have been
allocated by the user).
5. Initial
This data is disabled in the current version.
Note:
The maximum number of symbol definitions varies by PLC type.
