(7) Sampling/periodic setting (Buffer memory addresses CH1: A
H
,
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 10= 4200 [ms]
(8) Sampling/periodic counter flag (Buffer memory addresses CH1: B
H
,
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 Buffer memory content
Idling function 0
Executing function 1
(9) Latch count value (Buffer memory addresses CH1: C
H
to D
H
,
CH2: 2C
H
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
H
to F
H
,
CH2: 2E
H
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
H
to 13
H
, CH2: 30
H
to 33
H
)
• 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
H
to 17
H
, CH2: 34
H
to 37
H
)
• 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).
