① D8 and D9 are not used in this example.
The steps of the sequencer can be viewed on your PLC-5 programming
software using the Data Monitor Command to view file #N7:0 file array.
The resulting message would be displayed:
TIMER T4:1 = 287
The variable 287 on the above display is the accumulated value for T4:1, free
running timer.
