2-8-2 Operation of Timer Instructions
There is an option called Apply the same spec as T0-2047 to T2048-4095 in
the PLC properties. This setting affects the operation of timers as described in
this section.
Selecting the Option If this option is selected, all timers will operate the same regardless of timer
