6 Buffer memory
6.2.10 Set Integrated value setting target (Un \ G51) and Integrated value setting value (Un \ G52, 53)
(1) Setting procedure
(a) Set the integrated value setting target in the buffer memory. Setting range is as follows:
(b) Set the integrated value setting value in the buffer memory.
- Configurable range: 0 to 999999999
- The unit used for the setting value is the same as that used for the electric energy and
reactive energy that are output to the buffer memory.
For details, refer to section 6.3.1.
(c) Turn Integrated valve set request (YnC) from OFF to ON to enable* the setting.
* When the setting is enabled, Integrated valve set completion flag (XnC) changes from OFF to
ON.
(2) Default value
Integrated value setting target (Un\G51) is set to 0 (No set).
Integrated value setting value (Un\G52, Un\G53) is set to 0.
6.2.11 Output period of data acquisition clock (Un \ G60, 61)
Set the period of the data acquisition clock (Xn8).
(1) Setting procedure
(a) Set the output period of data acquisition clock in the buffer memory. Setting range is as follows
- Configurable range: 0 to 86400000 (ms)
* If set the output period of data acquisition clock to 0, the data acquisition clock (Xn8) will be
turned off all the time.
(b). Because the data update cycle is 250ms, data acquisition clock operate in unit of 250ms.
However, if the output period of data acquisition clock is not a multiple of 250ms, data
acquisition clock will turn on at the timing of the first data update after the output period of
data acquisition clock.
・For example
Output period of data acquisition clock : 800ms
Times of updating measurement data = quotient 3 + surplus 50ms
The input device (Xn8) will turn on once every four times of measurement data update.
As a result, the output period of data acquisition clock will be the same as the case of
1000ms
(c) Turn Operating condition setting request (Yn9) from OFF to ON to and enable the setting.
(2) Default value
It is set to 0 (milliseconds).
