(3) Operation example of the periodic pulse counter function
The following figure shows an operation example of storing each calculated value in CH  Periodic pulse count,
difference value (RWr12 to RWr13, RWr2A to RWr2B), CH  Periodic pulse count, present value (RWr14 to
RWr15, RWr2C to RWr2D), and CH  Periodic pulse count value update check (RWr16 to RWr17, RWr2E to
RWr2F) based on the value in CH  Present value (RWr10 to RWr11, RWr28 to RWr29) counted within the preset
cycle time (1ms).
