Infomation Mangagment Data Quality Codes
In an 800xA SV6. 6.0.3 we are reading historical data Information connection.
In some cases, and in some short time period we obtained quality codes not documented in “3BUF001094-600_A_en_System_800xA_Information_Management_6.0_Data_Access_and_Rep
I made an inverse engineering and I decodified what the bits mean.
This is the result:
Bit 7 and 8, Good data, decimal 192.
Bit 7, Uncertain data, decimal 64.
Bit 17, Duplicated time stamps.
Bit 18, interpolated.
Bit 19, raw data.
Bit 20, calculated data.
Bit 22, no data.
Bit 23, data lost.
I didn’t can identify the meaning of Bit 25 and Bit 29.
OPC documentation says that bits are defined by de manufacturer and in this case is de ABB AC800 OPC.
