Chapter 11 Datalog Function
(c) Release Value Setting
Among Event Save functions, release value setting can be done only in WORD Condition. It affects data save
interval and frequency. Once the release value is set, the condition after event occurrence saves data until the
release value is satisfied.

Value Setting
%MW0 > 100
☞ Release Value Setting 50
Saves data until the setting value after event
Saves data until the
condition is met after
event occurrence
%MW0 >= 100
%MW0 == 100 Release Value Cannot be Set
%MW0 < 100
☞
Saves data until the setting value after event
%MW0 <= 100
%MW0 <> 100 Release Value Cannot be Set
Note
Release value can be set as follows. If the following is not complied with, an error window will appear
and data input will not work. Check it when setting the parameter.
☞ Release value many not overlap with the range of set values.
Condition Range of Release Value
Set Value >= Release Value
Set Value > Release Value
Set Value <= Release Value
Set Value <= Release Value
Setting Available
Example 1) In the word condition, if the value is set to %MW0>100, and the cancelation value is set to 50.
☞ If %MW0 exceeds 100, an event occurs, and the data is saved. However, since the cancelation value is set
to 50, the data storage is performed until it reaches 50.
☞ When the condition is met, the data is saved at the point of time set in the even occurrence condition.
[Rise], [Fall], [Transition] conditions store 1 block of data by operation, and [ON],[OFF] conditions store data
until the conditions are not met by the level operation.
