MOD 30ML Functions
BUILT-IN ANALOG INPUT BLOCK
15 Initial Result (R) ................................................................................................................ CWR
The initial result is the value used when the block is initially downloaded. It is entered in the
units specified by the input type selected during configuration (ohms for an RTD input). This
value is overwritten when the block first executes. Subsequent values are the result of block
evaluation. This is the actual field result floating point value to the instrument when the block
is in auto. This is a writeable floating-point data value when the block is in manual, the I/O is
locked, or the instrument state is not run. Result values are written and read in the units of
the configured input type.
16 Result Quality (RQ)........................................................................................................... – WR
This data quality field will go BAD if any of the block diagnostic errors become active while
the block is in auto. Writeable only when the block is in MANUAL, the I/O is locked or the
instrument state is not run.
17 Field result (FR) ................................................................................................................ – – R
This is the input value calculated from the raw voltages read from the built-in circuit. See
Attribute #52 and Table 2-9.
18 Field Result Quality (FRQ)............................................................................................... – – R
The field result data quality will go bad if any of the block diagnostic errors become active.
20 Reference Voltage Low (VRLO)....................................................................................... – – R
The reference voltage value from the input circuit in millivolts. Corresponds to B2-B0 counts.
21 Zero counts, low (ZLO)..................................................................................................... – – R
The zero value from the input circuit in counts. Corresponds to B3 - B0 at 0.
22 Reference voltage, high (VRHI)....................................................................................... – – R
The reference voltage value from the input circuit in volts. Corresponds to B2-B0 counts.
23 Zero counts, high (ZHI) .................................................................................................... – – R
Zero reading from the input circuit in counts. Corresponds to B3 - B0 at 0.
24 Input resistance (INR) ...................................................................................................... – – R
Measured value of the current input resistance.
25 Resistance zero (RZERO) ............................................................................................... – – R
The RTD value at 0 resistance.
26 CJC mV at Zero °C (CJV0) ............................................................................................... – – R
The cold junction compensation value in millivolts at 0 °C.
27 Temperature Coefficient (CJTC) .................................................................................... – – R
The temperature coefficient of the cold junction compensator in °C/mV.
