Dear All,
Hope you are doing well
Please consider my below query and guide me on this.
My Task:
Reading VFD operational Data over Modbus
Ignition Version:
8.1 and Paid License
Issue Facing:
1.) On the analog nature tag (like Current, Voltage, Frequency etc) enabled the “Tag History” option, when I am setting the Sampling Mode to “On Change”, no values are logging in the database. Even I changed the Minimum Sampling time and Deadband values. The values are only logged, when the Maximum Sampling time has past, like I set it to 1 minute/1 hr.
What I have observed that, the logging is happening but the ‘time of logging’ is quite weird it is of year 1969 (see in picture 1 below)
2.) When I am setting the Sampling Mode to “Periodic” and set the sampling time to 1 sec, Values are still not logged in the database after every 1 sec (like it should a/c to periodic definition), but they are only logged whenever the values are changed. It is behaving like the ‘On Change’ mode.
Here the logging time is correct (see in picture 2 below)
I have already done the restarting of ‘Tag History’ module but no success.
Please guide me in this, as this project is stuck because of this issue… I have to use the power chart for the operational data trending, but facing this logging issue.
