6.3.5 Temperature element status
Table 6-8 shows measurement status messages for temperature elements connected to a Rosemount
2240S Multi-input Temperature Transmitter.
You can view status registers by using the View Diagnostic Registers function or the View Input Registers
function in TankMaster WinSetup, see
“Diagnostics” on page 110 and “Viewing input and holding
registers” on page 108 .
Table 6-8. Status registers for temperature elements connected to a Rosemount 2240S
Message Description
Temp_1
Input register no. 200 (1) .
Temperature measured by element no. 1
1. The register number refers to the internal Input Register in the Rosemount 2240S database.
Status_1
Input register no. 202
Status for temperature element 1:
Bit 0: Not Connected or disabled by SW (This causes the Temperature value to
be -300 °C).
Bit 1: Temperature is under the Lower Temperature Limit
Bit 2: Temperature is above the Upper Temperature Limit.
Bit 3: Measured resistance is outside the linearization table (This causes the
Temperature value to be -300 °C).
Bit 4: Sensor short circuit
Bit 5: Sensor short circuit to ground
Bit 6: Sensor open circuit
Bit 7: ADC communication error
Bit 8: ADC HW error
Bit 9: MI Approved Value
Bit 10: Invalid Linearization Table (This bit causes the Temp. value to be -300).
Bit 11: Invalid conversion formula. Check the constants in the User defined
formula.
Bit 12: Power up.
Bit 13: Simulated Value
Bit 14: ADC data is not valid.
Bit 15: Invalid Data.
