266CRH / 266CRT, 266CSH / 266CST MULTIVARIABLE PRESSURE TRANSMITTER | OI/266CXX/MODBUS-EN REV. A 75
Application of the Diagnosis Main and Main 2 Registers
The 266CRH / 266CRT, 266CSH / 266CST has two ‘Diagnosis’
(Diagnosis Main and Main 2). The Diagnosis Main register
(Address 411, 412) each containing 16 bits.
The Diagnosis Main 2 register (Address 413) containing 16 bits.
Each bit represents an error.
The registers are structured as follows:
M11191
411 412 414
= true (1) = false (0)
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
Figure 3: Diagnosis Main Register (Example, 16-bit Register)
The bit position is assigned to the errors in accordance with the
’Bit’ column in the table
Diagnosis codes .
The following assignment applies to the example in Figure 3 :
