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

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.
