Commands And Command-Specific Response Codes; Universal Commands; Common Practice Commands - ABB 691HT Operating Instructions Manual

ELECTRONICS TEMP OUT OF LIM (pressure Txs)
The temperature of the electronics appears outside of the
specification limits: check in field and, if true, provide
adequate protection to prevent excess temperature of the
transmitter's topwork due to radiation, freezing, etc. If the
topwork temperature appears regular the electronics is
faulty and should be replaced.
ASIC UPDATE FAILURE (pressure transmitters)
The ASIC input is not being updated. Check connector
between sensor and electronics. In 600T tx. possible
fault of the sensor or primary electronics.
ASIC COUNTER OUT OF LIMITS (pressure Txs)
The ASIC input is outside of its physical limits. Check
sensor connector or the sensor. Possible fault of the
sensor or primary electronics.
DAC VALUE OUT OF PHYSICAL LIMITS
(600T EN pressure transmitters)
The analog output trimming values are incorrect. It is
necessary to perform a 4-20 mA trimming (DAC Trim) to
correct the output signal indication.

COMMANDS AND COMMAND-SPECIFIC RESPONSE CODES

This section contains Hart Commands involved in Hand
Held Communicator operations with the Response
Codes, that may appear on its display. It also contains
a brief explanation of warning and error messages.
When an error occurs during a command execution a
message is displayed, indicating the number of the
command and the relevant Response Code:
COMMAND# XX
Response Code YY
The list below represents the reference guide for the
user illustrating the meaning of each Command-Speci-
fic Response Code.

UNIVERSAL COMMANDS

COMMAND 6: WRITE POLLING ADDRESS
Command-Specific Response Codes
7 In Write Protect Mode
the write protect link on the transmitter is "on"
COMMAND 18: WRITE TAG, DESCRIPTOR, DATE
Command-Specific Response Codes
7 In Write Protect Mode
the write protect link on the transmitter is "on"

COMMON PRACTICE COMMANDS

COMMAND 34: WRITE PRIMARY VARIABLE DAM-
PING VALUE
Command-Specific Response Codes
3 Passed Parameter too Large
For 652/653 S temperature transmitter
ADC ERROR
INCONGRUENT MEASUREMENT
XOR ERROR
ERROR IN ADC BITS
WATCHDOG TIME/OUT
EEPROM / ADC ERROR
EEPROM / ADC ERROR DW
RAM / XOR ERROR DW
EEPROM / XOR ERROR DW
EEPROM ACK ERROR
All the above errors are HARDWARE errors related to
the transmitter electronic.
Consider to replace the electronic. Please refer to the
manufacturer for additional explanation.
ERROR ON MEASUREMENT 1
ERROR ON MEASUREMENT 2
ERROR ON CJC / ELECTRONIC TEMPERATURE
All the above errors are errors related to the measurement
sensor 1 or 2.
Verify the sensor 1 or 2 status and if the failure persists
consider to replace the measurement sensor.
4 Passed Parameter too Small
the damping value range is 0 to 16 seconds
7 In Write Protect Mode
the write protect link on the transmitter is "on"
8 Warning: Set to Nearest Possible Value
the damping values are 0, 0.25,0.5,1,2,4,8,16.
COMMAND 35: WRITE RANGE VALUES
Command-Specific Response Codes
2 Invalid Selection
7 In Write Protect Mode
the write protect link on the transmitter is "on"
9 Lower Range Value too High
10 Lower Range Value too Low
11 Upper Range Value too High
12 Upper Range Value too Low
13 Upper and Lower Range Values Out-of-Limits
14 Span too Small
COMMAND 36: SET UPPER RANGE VALUE ( SPAN
Push Button)
Command-Specific Response Codes
7 In Write Protect Mode
the write protect link on the transmitter is "on"
9 Applied Process too High
10 Applied Process too Low
the applied pressure exceed the Range limits
14 Span too Small
the resulting span is too small
COMMAND 37: SET LOWER RANGE VALUE ( ZERO
Push Button)
Command-Specific Response Codes
7 In Write Protect Mode
the write protect link on the transmitter is "on"
