Hello everyone,

We are operating a gas turbine power plant with a GE Mark V HMI control system.

After executing the EEPROM UP T1 R TOTD command, the TOTD_Q.AP1 file was updated. However, when we open the file with Notepad, the contents appear as garbled characters.

Could anyone please advise how to view the data stored in TOTD_Q.AP1 within the GE Mark V system? Is there a built-in tool or a specific utility for reading or displaying the contents of this file?

Thank you in advance for your assistance.

 

@DGY,

The <Q>Totalizer Data File, TOTD_Q.AP1, is not intended to be viewed, read or analyzed by any program. It is just a place to store the contents of the <Q> processors totalizer data (Fired Hours; Starts; Trips; etc.). It is purposely "written" in hexadecimal code that is not accessible to anyone other than the OEM (Original Equipment Manufacturer) because the information it can contain can affect warranted conditions (mostly when the machine is new).

The fact that it can be uploaded and downloaded has historically caused more problems than it was ever intended to solve. It's one reason why the recommended EEPROM Downloader options don't include the file by default because it can overwrite the contents of the <Q> processors EEPROM, and that usually upsets most Operations Supervisors and Plant Managers very much.
