24.1 Overview
"Tag editing" is a function used to give names (tags) to addresses of PLC memory or internal memory
($u, $L, etc.) and use these names for screen data creation.
There are two methods for tag designation: address designation and variable designation.
Address Designation
Give a tag name to the address of PLC memory or internal memory, and set the memory address for
the part or item with the given name.
Example: On the [Tag Database Edit] window, register PLC memory addresses "M0", "D100" and
"D101" with names "Alarm 1", "Frequency" and "Acceleration Time", respectively.
Set memory addresses for parts by using tags.
Lamp memory:
Numerical data memory: "Frequency" (D100), "Acceleration time" (D101)
