Transducer Block Parameters Description
VALVE_TYPE The type of the valve as defined in Fieldbus Transducer Specifications
(FF-903) in Section 4.7 Valve Type. Reference Bulletin LMENIM2306
(MX); LMENIM3306 (QX).
SCALED_VALUES Scaled Information.
Subparameter 0 uint16_var Indicates if APT and ATT configuration are selected. Refer to Bulletin
LMENIM2306 (MX); LMENIM3306 (QX), Installation and Operation
Manual for definitions of APT and ATT.
Subparameter 1 uint16_var APT Output Value. APT is an Analog Position Transmitter representing
valve position (40-20 mA or 0-10 VDC). A Read-only, 16-bit unsigned
value. APT option MUST be enabled for a value to be displayed in
this register. Reports the APT output signal value as configured in
0-100 increments of span. Referenced as terminal points 18 and 17
(common) for mA output.
Subparameter 2 uint16_var ATT Value. ATT is an Analog Torque Transmitter representing actuator
output torque (40-20 mA or 0-10 VDC). A read only 16•bit unsigned
value. ATT option MUST be enabled for a value to be displayed in this
register. Reports the ATT output signal value as configured in 0-100
increments of span. Referenced as terminal points 16 and 1 (common)
for mA output.
DIAGNOSTIC_VALUES Diagnostic Information.
Subparameter 0 uint16_var Unused.
Subparameter 1 uint16_var Measured Voltage on the 3-Phase Power. Diagnostic use only.
Subparameter 2 uint16_var Continuous Position Feedback. read only 16-bit unsigned integer. Scale
is 0-100 increments of open.
VALVE_STATUS Valve Status Information.
Subparameter 0 uint16_var DO_Readback Data Channel – Displays last value request by host.
Bit 00 – S1 or R1 (optional)
Bit 01 – S2 or R2 (optional)
Bit 02 – R3 (optional)
Bit 03 – R4 (optional)
Bit 04 – R5 (optional)
Bit 05 – R6 (optional)
Bit 06 – R7 (optional)
Bit 07 – R8 (optional)
Subparameter 1 uint16_var Valve Status. Read only. Contains most desired indications of field unit
status.
Bit 00 Open – Valve is fully opened. This bit is ORd with bits 01, 02, 03,
04. Value of 1=True, Value of 0=False.
Bit 01 Close – Valve is fully closed. This bit is ORd with bits 00, 02, 03,
04. Value of 1=True, Value of 0=False.
Bit 02 Stopped in Mid-Travel – Valve stopped in mid-travel, and neither
the Open or Closed limit switch is engaged. This bit is ORd with bits 00,
01, 03, 04. Value of 1=True, Value of 0=False.
Bit 03 Opening – Valve is traveling in the Open direction. This bit is ORd
with bits 00, 01, 02, 04. Value of 1=True, Value of 0=False.
