Sampling Counter Function

The sampling counter function counts pulses that are input during the specified sampling period (T) and stores it as
CH Sampling count value (RWr12 to RWr13, RWr2A to RWr2B) in the remote register.
(1) Setting method of the sampling counter function
1.
Set "Parameter write" for "Method selection".
"CC IE Field Configuration" window
2.
Select "2: Sampling Counter Function" in "CH Counter function selection".
(2) Setting of the sampling period
Set the sampling period (T) by setting values to CH Cycle setting (Sampling counter/Periodic pulse counter)
(RWw17, RWw2F) and CH Time unit setting (Sampling counter/Periodic pulse counter) (RWw16, RWw2E).
When CH Setting change request (Sampling counter/Periodic pulse counter) (RY27, RY3F) is turned off then
on, the setting values are enabled.
However, the setting values are enabled from the next operation of sampling counter function if the settings are
changed while the sampling counter function is being performed.
Setting item
CH Time unit setting (Sampling counter/Periodic pulse
counter) (RWw16, RWw2E)
CH Cycle setting (Sampling counter/Periodic pulse counter)
(RWw17, RWw2F)
● Change the sampling period by CH Setting change request (Sampling counter/Periodic pulse counter) (RY27, RY3F).
When the period is changed by Initial data processing completion flag (RY8) or Initial data setting request flag (RY9), the
items of the monitor value such as CH Present value (RWr10 to RWr11, RWr28 to RWr29) are cleared.
● When changing the sampling period by using CH Setting change request (Sampling counter/Periodic pulse counter)
(RY27, RY3F), note the following:
Do not execute the sampling counter function by CH Function input terminal (FUNC1, FUNC2) from when CH Setting
change request (Sampling counter/Periodic pulse counter) (RY27, RY3F) is turned on until CH Setting change
completed (Sampling counter/Periodic pulse counter) (RX27, RX3F) turns on. Doing so may perform counting with the
previous setting.
