„ Automatic Register Number Allocation for Symbols
All symbols in the AUTO range will be automatically allocated to register numbers starting
with any number.
If a symbol name is entered that has not been allocated to a register number in the program
window, meaning the symbol has not been defined, open the Symbol Definition Tab Page to
display the symbols in a table like the one shown below.
Normally, symbols would be automatically allocated when the Range column shows AUTO.
If, however, a register number has already been set in the No. of Register column, either by
previous automatic allocation or manual input of register numbers, symbols will not be allo-
cated automatically for those register numbers even if the Range column shows AUTO.

Symbols can be automatically allocated to D and M registers starting from a specified num-
ber. Use the following procedure to automatically allocate D and M registers.
1. Enter the symbol definition data to allocate as shown below.
2. Select Data (D), Auto Number (A), and then AUTO (A) from the programming menus.
3. The Automatic Symbol Allocation (D, M) Window will be displayed. Input the leading
register numbers from which to allocate local registers (D) and global registers (M), and
then click the Set Button.
The register numbers will be automatically allocated and displayed.
In this example, DATA1 is set to integer D register data with a data size of 1, DATA2 is
