Periodic Pulse Counter Function

The periodic pulse counter function stores the values which are stored in CH Present value (RWr10 to RWr11,
RWr28 to RWr29) and CH Periodic pulse count, difference value (RWr12 to RWr13, RWr2A to RWr2B) in the remote
register every specified cycle time (T).
(1) Setting method of the periodic pulse counter function
1.
Set "Parameter write" for "Method selection".
"CC IE Field Configuration" window
2.
Select "3: Periodic Pulse Counter Function" in "CH Counter function selection".
(2) Setting of the cycle time
Set the cycle time (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 periodic pulse counter function if the setting is
changed while the periodic pulse 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 cycle time by CH Setting change request (Sampling counter/Periodic pulse counter) (RY27, RY3F). When
the cycle time 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 cycle time by using CH Setting change request (Sampling counter/Periodic pulse counter) (RY27,
RY3F), note the following:
Do not execute the periodic pulse 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.
