About tag filters
Tag filters are functions that perform real-time conversion processing on raw values obtained from devices. A typical example is "Engineering value conversion (by range)".
Tag filters can be defined individually for each tag, and when multiple filter functions are specified, they are executed in the order of the filter numbers. When a tag filter is executed, the value may be converted into a different type, and the result of the conversion by the last filter executed will be the final data type of the tag filter. After conversion by the tag filter, the value is finally converted into the type specified in the "Type conversion" setting and stored in the tag.
For example, in the example settings below, "01 Engineering value conversion (by range)" will be executed followed by "02 Find moving average".
Also, because the type conversion setting is set to "default," the data type will be that of the moving average filter processing result, that is, a numeric tag.
