Transducer Block Parameters
Description
Bit 04 Closing – Valve is traveling in the Close direction. This bit is ORd
with bits 00, 01, 02, 03. Value of 1=True, Value of 0=False.
Bit 05 Valve Jammed – Valve is jammed. The valve was traveling
or attempting to travel in either the Open or Close direction and has
tripped the torque switch. This bit is ONLY active if the actuator should
be commanded to move by the pushbutton station or remote control,
and an over-torque condition occurs. Value of 1=True, Value of 0=False.
Bit 06 NOT in Remote – Monitors the actuator LCS. Indicates the LCS
has been switched to the Local or Stop position. The host will not be
able to control the actuator. Value of 1=True, Value of 0=False.
Transducer Block Parameters
Description
Bit 06 ESD Conflict
Bit 07 Inhibit Conflict
Bit 08 CSE in local/stop. Input must be set for CSE and enabled.
Bit 09 Stop Selected – Monitors the actual Local Control Station (LSC).
Indicates the LCS has been switched to the Stop position. The Host
and local control station do not have control of the actuator. Value of
1=True, Value of 0= False
Bit 10 Network ESD is ON – Indicates field unit has been issued a
network ESD command. The field unit will command the actuator to
operate to the preconfigured position (Open, Close, Stop, Ignore). The
network ESD command must be terminated to reset this bit. Value of
1=True, Value of 0=False.
Bit 11 Local ESD is ON – Indicates field unit has been issued a local
ESD command. The field unit will command the actuator to operate to
the preconfigured position (Open, Close, Stop, Ignore). The local ESD
command must be terminated to reset this bit. Value of 1=True, Value
of 0=False.
Bit 12 Unit Reset Since Last Poll – Indicates field unit has reset since
the last network poll. This bit is latched until read by the host controller.
Value of 1=True, Value of 0=False.
Bit 13 Local or Stop Selected – Monitors the actual Local Control
Station (LSC). Indicates the LCS has been switched to the Local or Stop
position. The Host and local control station do not have control of the
actuator. Value of 1=True, Value of 0=False.
Bit 14 Opening in Local Mode – Monitors the actuator LCS Open
switch. Indicates the actuator LCS has been switched to the Local
position AND the actuator is being opened from the LCS. The host does
not have control of the actuator. Value of 1=True, Value of 0=False.
Bit 15 Closing in Local Mode – Monitors the actuator LCS Close
switch. Indicates the actuator LCS has been switched to the Local
position AND the actuator is being closed from the LCS. The host does
not have control of the actuator. Value of 1=True, Value of 0=False.
Subparameter 3 uint16_var
Additional Status. Digital Outputs register. read only 16-bit unsigned
value. Contains additional field unit status. Optional for controlling a
field unit.
Bit 00 Close – Indicates the field unit close contactor is engaged and
the valve is moving in the close direction. This bit is ORd with Bit 01 in
this register. Value of 1=True, Value of 0=False.
Bit 01 Open– Indicates the field unit open contactor is engaged and the
valve is moving in the open direction. This bit is ORd with Bit 00 in this
register. Value of 1=True, Value of 0=False.
Bit 02 User Output S1 or R1 (optional) – Indicates the field unit AS-1
Relay has been energized. This relay is configurable to operate under
many conditions including FF control. Verify current configuration using
the LCS. This is a latched digital output, referenced as terminal points
1 and 2.
Bit 03 User Output S2 or R2 (optional) – Indicates the field unit AS-2
Relay has been energized. This relay is configurable to operate under
many conditions including FF control. Verify current configuration using
the LCS. This is a latched digital output, referenced as terminal points
3 and 4.
