Programming with symbols

So far you have been working in the PLC program with operands in the "PLC language"

such as I0.3 or T34, but if the program is longer, it is not easy to associate these operands

with their actual function within a control system. The program would be easier to read if we

could switch the operand names to plain text. This is exactly what you can do with symbolic

programming.
