When a selected counting function is operated, the counted value for the function is stored in the following buffer memory.
| Current Value | Counted Value | |||
Latch-counted Value | Sampling-counted Value | Previous Periodic-pulse-counted Value | Current Periodic-pulse-counted Value | ||
CH1 | 0H, 1H | 04H, 05H | 06H, 07H | 08H, 09H | 0AH, 0BH |
CH2 | 20H, 21H | 24H, 25H | 26H, 27H | 28H, 29H | 2AH, 2BH |
A currently counted value is stored in buffer memory in signed 32-bit value. The value is automatically revised according to counting form.
Point
The counted value in buffer memory is to be read in two words by DFRO command. If the value is read one word by one word while it is being revised, the value of the upper word and the lower word may be wrong.
Ex 1. Right
Ex 2. Wrong
