Any Possibility to logging Indicator updation History?

[gowthameie]

I want to maintain the separate text file history of Warning /Error Message while doing testing.

if Oil level is lower than defined range, in string indicator will display " Oil Level is Low". Similar kind of health monitoring  feature will be maintained during testing.

I just want to do logging to  maintain the history of message displayed in that string indicator. Whenever new warning/error message is updating in the string indicator. New Warning/Error Message also to be appended with existing data.

For example, i am expecting my test file should contain following items

29/03.2021 01.13 PM Oil Level is low

29/03.2021  02.13 PM Oil temperature is high

how to achieve this task?

Hi Gowthameie,

You should use "Set File Position Function" available in File IO function programming palette to achieve this. It moves the position of the current file mark of the file identified by refnum to the position indicated by offset (in bytes) according to the mode in from. You can use "end" this will set the marker at end and the logging will be appended at the end.

Refer to following example code (you have create text file before running this).

I hope this helps.
