Transducer Block Parameters Description
DTM_OPERATION DTM operation can be set from the DCS/ Configurators to
DTM_READ_ONLY or DTM_READ_WRITE. In DTM_READ_
WRITE mode the actuator does not respond to commands from
DCS/Configurators.
REMOTE_INPUT_MODE The actuator can be placed in various modes. Multi Control
mode: This mode allows analog, digital and network control
modes of operation to the actuator. Digital Control: The unit
will operate only upon the last digital input command received.
Network Control: The unit will operate only upon the last
network command received. Analog Control: The unit will
operate only upon the last analog input command received.
NETWORK_SETPOINT_MODE User selectable network setpoint mode from DCS/DTM/
Configurators. REMOTE_DTM mode is effective only when
DTM_OPERATION is in DTM_READ_WRITE.
PROPORTIONAL_BAND Proportional band is the range of errors between position and
demand signal that will produce reduced speed. Range: 10 to
1000. Increment: 10. Scaled to 100.
DEADBAND The deadband should be wide enough to prevent hunting of the
actuator but as low as possible to give adequate response to
changes in the error signal. Range: 10 to 500. Increment: 10.
Scaled to 100.
ANALOG_SCALING Analog scaling allows the user to change the signal range from
the default range.
ACT_OPT_HARDWARES Optional electronics connected to the actuator.
