Notes on Inserting Symbols
• You enter the variable you want to modify with your address or as a symbol. You can enter
symbols and addresses either in the "Symbol" column or in the "Address" column. The entry is
then written automatically in the correct column.
If the corresponding symbol is defined in the symbol table, the symbol column or the address
column is filled out automatically.
• You can enter only those symbols that are already defined in the symbol table.
• You must enter a symbol exactly as it is defined in the symbol table.
• Symbol names that contain special characters must be enclosed in quotation marks (for
example, "Motor.Off," "Motor+Off," "Motor-Off").
• To define new symbols in the symbol table select the menu command Options > Symbol
Table. Symbol can also be copied from the symbol table and pasted in a variable table.
Syntax Check
When you enter variables in the variable table, a syntax check is carried out at the end of each line.
Any incorrect entries are marked in red.
