InTouch HMI Historical Data Logging (Native)

AHMET SERDAR YILDIZ

Hello everyone,As I have seen from the videos, I want to make historical data records and show this through trends. However, I cannot see a file with the .LGH extension in the folder I am directed to.I shared the file contents with images.I am waiting for your help. Thank you.

    With that setup, make sure the user that is logged into the OS and running WindowViewer has permissions to write to that folder. 

    Also, the folders in the image in the middle, the Data/1 folder, looks like the setup for having InTouch log to a Historian.  Not sure if that is still on or not.

    Make sure your application is not set to be an "InTouch View App".  This type has a cheaper license, is intended for using InTouch to get data/history/alarms from Application Server.

    I'm assuming that View is running, and that you have some tags that are getting data, and that some of those tags have "Log Data" Enabled on the tag, it should create an LGH and IDX file for the data files for trends.
