Parameter |
Can Configure? |
Description |
|---|---|---|
|
COLD_START |
No |
HART status bit #5. Indicates if the HART field device went thru a power cycle. The device clears it after the first response. |
|
CONFIG_CHANGED |
No |
HART status bit #6. Indicates if a configuration change has been made on the HART field device. On detection the scale and units are uploaded automatically and flag cleared. |
|
DEV_CFG_MISMATCH |
No |
Indicates if the physically installed device does not match the configured device. |
|
DEV_MALFUNC |
No |
Set and cleared by tracking Field Device Malfunction (HART status bit #7) from the HART instrument. If the HART instrument detects a malfunction within itself, this parameter is set to True (1). |
|
DV_SLOT0_CODE |
Yes |
The slot 0 device variable code sent digitally from the CHARM. Defines the HART variable whose data is reported by HART_VAL0. |
|
DV_SLOT1_CODE |
Yes |
The slot 1 device variable code sent digitally from the CHARM. Defines the HART variable whose data is reported by HART_VAL1. |
|
DV_SLOT2_CODE |
Yes |
The slot 2 device variable code sent digitally from the CHARM. Defines the HART variable whose data is reported by HART_VAL2. |
|
DV_SLOT3_CODE |
Yes |
The slot 3 device variable code sent digitally from the CHARM. Defines the HART variable whose data is reported by HART_VAL3. |
|
DV_SLOT_CONFIG |
Yes |
The mask that determines which HART slots are enabled. |
|
HART_DV_SLOT0 |
No |
The slot 0 device variable value. This value is read digitally. |
|
HART_DV_SLOT1 |
No |
The slot 1 device variable value. This value is read digitally. |
|
HART_DV_SLOT2 |
No |
The slot 2 device variable value. This value is read digitally. |
|
HART_DV_SLOT3 |
No |
The slot 3 device variable value. This value is read digitally. |
|
HART_ERRORS |
Yes |
Allows the screening of status error messages generated by the transmitter. |
|
HART_PV |
No |
The Primary Variable returned by the HART transmitter, in engineering units. This value is read digitally. |
|
HART_SV |
No |
The Secondary Variable returned by the HART transmitter, in engineering units. This value is read digitally. |
|
HART_TV |
No |
The Tertiary Variable returned by the HART transmitter, in engineering units. This value is read digitally. |
|
HART_FV |
No |
The Fourth Variable returned by the HART transmitter, in engineering units. This value is read digitally. |
|
HINTEG |
No |
For HART analog input and output, HINTEG indicates that a HART error is present (0=Good, 1=Bad) even if HART_ERRORS is configured to ignore the error. When HART_ERRORS is configured to ignore one or more HART errors, a corresponding active HART error does not contribute to Bad OINTEG; however, it does contribute to Bad HINTEG. HINTEG is always Bad when OINTEG is Bad. |
|
LONG_TAG |
No |
The device long tag name for a HART device. The HART device long tag name can have up to 32 characters from the ISO Latin-1 character set. Note Device long tag names are not supported for devices implementing the HART Protocol prior to revision 7. |
|
MORE_STATUS |
No |
HART status bit #4. Indicates if there are additional details that the devices can return. If this is set use AMS Device Manager or HART handheld device to get additional information. |
|
NO_COMM |
No |
Set to True (1) if digital communication with the HART instrument has stopped or was never started. If digital communication is successful, this parameter is set to False (0) immediately. |
|
NPV_PAST_LIM |
No |
Set and cleared by tracking the Non-Primary Variable Out of Limits (HART status bit #1) from a HART instrument. If one of the measured non-Primary Variables is outside its sensor operating limits (high or low), this parameter is set to True (1). |
|
OUT |
No |
The current value driven to the CHARM, in percent, and the status of the output. |
|
PV_FIXED |
No |
Set and cleared by tracking the Process Variable Analog Output Fixed (HART status bit #3) from a HART instrument. If the HART device analog output value is fixed to a requested value, this parameter is set to True (1). |
|
PV_PAST_LIM |
No |
Set and cleared by tracking the Primary Variable Out of Limits (HART status bit #0) from a HART instrument. If the measured Primary Variable is outside the sensor operating limits (high or low), this parameter is set to True (1). |
|
PV_SAT |
No |
Set and cleared by tracking the Primary Variable Analog Output Saturated (HART status bit #2) from a HART instrument. If the analog output from the HART device is out of range (high or low), this parameter is set to True (1). |
