5)
Sampling pulse number indication
The value obtained by performing pre-scale conversion on the pulse
number entered in the count cycle set to the count cycle setting value is
displayed. If the input pulse number is not uniform, movement averaging
processing can be performed to average the input pulse number.
The count range is 0 to 32767.
6)
Accumulating count value indication
The accumulating value of the sampling pulse number is displayed in the
set count cycle. The count range is 0 to 99999999, and you can select
whether to use the accumulating counter as the linear counter or ring
counter.
7)
Input pulse value indication
The pulse number actually input is displayed every 10ms. Since the input
pulse number is displayed every 10ms, the module can be used as a
counter. (The input pulse value is updated every 10ms. Note this when
using the module as a counter.)
The count range is 0 to 2147483647.
8)
Alarm output
It is allowed to set four setting values, i.e. upper/upper limit value,
upper/lower limit value, lower/upper limit value and lower/lower limit value,
for the sampling pulse number to output alarms.
9)
Accumulating counter overflow detection
If the accumulating count value overflows (exceeds 99999999) in the linear
counter mode, the accumulating counter overflow detection flag turns ON to
indicate that an overflow error has occurred.
10) Accumulating counter comparison output
If the accumulating count value reaches or exceeds the comparison output
setting value, the accumulating counter comparison flag turns ON.
11) Counter reset
The sampling pulse number, accumulating count value and input pulse
value can be reset at any timing.
(2) Counting speed range of the input pulse can be changed
By changing the input filter, the input pulse speed is available within the range 0
to 30kpps.
(3) 8 channels of pulse inputs in one module
One module has 8 channels of pulse inputs to configure a system at low costs.
(4) Channel isolated
The channels are isolated from each other. (Dielectric withstand voltage:
1780VAC for 1 minute)
