Transducer Block Parameters

Description

Subparameter 0

uint16_var

Unused

Subparameter 1

uint16_var

TP_START_POSITION – The position of the actuator when this

sampling period began (0 to 100% OPEN)

Subparameter 2

uint16_var

TP_STOP_POSITION – The position of the actuator when this

sampling period ended (0 to 100% OPEN)

Subparameter 3

uint16_var

TP_SAMPLE – The number of times that the torque value was sampled

for this TP sample. This value is also relative indicator of cycle

time and may be trended to identify when actuator performance is

changing. Cycle time is approximately equal to “TP Samples” times 50

milliseconds.

Subparameter 4

uint16_var

TP_MID_T_HIGH – The highest relative torque observed in midtravel

during this TP sample.

Subparameter 5

uint16_var

TP_MID_T_POS – The position of the actuator (0 to 100% OPEN) when

the highest mid-travel torque was observed.

Subparameter 6

uint16_var

TP_MID_T_AV_VAL – The average relative torque observed during this

TP sample.

Subparameter 7

uint16_var

TP_STOP_VAL – The relative torque observed at the moment when the

valve motion ended, completing this TP sample.

Subparameter 8

uint16_var

TP_BEFORE_MID_T_HIGH – The highest relative torque observed

while the actuator is in motion but before the limit switch was cleared

indicating that the actuator is in mid-travel. For example, if moving from

the CLOSED position, in the OPEN direction, this value represents the

highest relative torque value observed before the CLOSED limit switch

became inactive.

Subparameter 9

uint16_var

TP_AFTER_MID_T_HIGH – The highest relative torque observed

while the actuator is in motion after the limit switch became active

indicating that the actuator is no longer in mid-travel. For example, if

torque seated and moving from mid-travel, in the CLOSE direction, this

value represents the highest relative torque value observed after the

closed limit switch became active but before the torque switch stopped

movement.

SOFTWARE_VERSION

Device software version

FACTORY_DIAGNOSTIC

Internal use only

DOWNLOAD_PARAMETER

Internal use only

TARGET_ERROR

Internal use only

DTM_ARGUMENT

DTM specific parameter used in conjunction with DTM_COMMAND_ID

parameter for device manufacturer custom operations.

DTM_COMMAND_ID

DTM specific parameter used in conjunction with DTM_ARGUMENT

parameter for device manufacturer custom operations.

BULK_DATA

DTM specific parameter used for device manufacturer custom opera-

tions of uploading bulk data to DTM.

HARDWARE_FAULTS

The bit enumerated parameter provides hardware fault information

such as alarms and warnings. Bit value 1 indicates presence of alarm/

warning condition in the actuator.

Bit 00 SPI bus communication

Bit 01 to Bit 09 Not used

Bit 10 Valve jammed
