CH1 Overflow detection
• When the counter type is set to linear counter in the pulse count mode, or when the pulse measurement mode is set, the
overflow status of the counter is stored in this area.
• Either of the following values is stored based on the overflow status.
Status
No overflow detected
Overflow detected
■Buffer memory address
The following shows the buffer memory address of this area.

CH Overflow detection
CH1 Counter function selection setting
• A value to select the counter function is stored in this area.
• The following table shows the setting value for each function.
Counter function selection
Count disable function
Latch counter function
Sampling counter function

CH Counter function selection setting
CH1 Sampling/cycle time setting
A time value for the sampling counter function or cycle pulse counter function is stored in this area.
■Setting range
• The setting range is between 1 and 65535 (16-bit unsigned binary value).
• The unit of time differs depending on the counting speed setting.
Counting speed setting
500kpps or less
1Mpps or more
Ex.
When 500kpps is set in the counting speed setting and 420 is set in CH1 Sampling/cycle time setting (Un\G10), the function
operates at 4200ms (420  10ms).
