1. The counter counts up (the input U/D is set at 24 V). The counter reading
is 0. The timer interrupts. No count pulse received on the input CLOCK.
Control byte
Input bit B7 B6 B5 B4 B3 B2 B1 B0
Value 0 0 0 0 X X 0 0
Status byte
Output bit B7 B6 B5 B4 B3 B2 B1 B0
Value 0 0 0 0 X X 1 0
2. The cyclic period measurement is requested. The counter reading is 0. The
timer interrupts. No count pulse received on the input CLOCK.
Control byte
Input bit B7 B6 B5 B4 B3 B2 B1 B0
Value 0 0 1 0 X X 0 0
Status byte
Output bit B7 B6 B5 B4 B3 B2 B1 B0
Value 0 0 0 0 X X 1 0
3. The cyclic period measurement is started. The counter reading is 0. The
timer runs with the parameterized cycle time. Count pulses received on the
input CLOCK.
Control byte
Input bit B7 B6 B5 B4 B3 B2 B1 B0
Value
0 0 1 0 X X 0 0
Status byte
Output bit B7 B6 B5 B4 B3 B2 B1 B0
Value 0 0 1 0 X X 1 0
4. The cyclic period measurement is running. The counter reading is reset and
the timer is started again. The process data supply the number of impulses,
which were registered in the previous cycle.
