(7) Sampling/periodic setting (Buffer memory addresses CH1: A
CH2: 2A
)
H
• This area is used to write the time setting values of the sampling counter
function and periodic pulse counter function during counter function selection.
• The setting range is from 1 to 65535 (16-bit binary values) and the time unit is
10[ms].
Example) When 420 is set for the sampling/periodic setting in the buffer
memory
420
(8) Sampling/periodic counter flag (Buffer memory addresses CH1: B
CH2: 2B
)
H
• This area is used to store the function operating status while the sampling
counter function and periodic pulse counter function are being executed during
counter function selection.
• One of the values corresponding to the function operation status shown in the
table below is stored in this area.
Operating status
Idling function
Executing function
(9) Latch count value (Buffer memory addresses CH1: C
CH2: 2C
to 2D
H
• This area is used to store the latch count values when the latch counter
function is executed.
• The range of the values to be read is from –2147483648 to 2147483647 (32-bit
signed binary values).
(10) Sampling count value (Buffer memory addresses CH1: E
CH2: 2E
to 2F
H
• This area is used to store the sampling count values when the sampling
counter function is executed.
• The range of the values to be read is from –2147483648 to 2147483647 (32-bit
signed binary values).
(11) Periodic pulse count previous and present value
(Buffer memory addresses CH1: 10
• This area is used to store the present and previous values for the periodic
pulse count when the periodic pulse counter function is executed.
• The range of the values to be read is from –2147483648 to 2147483647 (32-bit
signed binary values).
(12) Ring counter minimum and maximum value
(Buffer memory addresses CH1: 14
• This area is used to set the count range when the counter format is ring counter.
• The setting range is from –2147483648 to 2147483647 (32-bit signed binary
values).
