Answer

Timers (or other FBs such as counters) each have an internal memory that is called an instance.
Therefore, after copying a timer, you need to define a variable for it. A variable is not defined by just copying and pasting a timer.
Right-click the copied timer, select 'Object Properties.' On the 'Function / Function Block Properties' dialog box, click the [OK] button to define a variable.
