Units Description
EU of PV Determines the low limit of the
compensation input.
None The proportional gain (multiplier) value.
None The proportional gain (multiplier) value for
IN_1.
None The proportional gain (multiplier) value for
IN_2.
None The proportional gain (multiplier) value for
IN_3.
None Options for controlling access of host
computers and local control panels to
operating, tuning, and alarm parameters
of the block. Not used by the transmitter.
Determined by The analog input value and status. The
source or EU of number of inputs is an extensible
PV_SCALE parameter in some function blocks.
Determined by The first analog input value and status.

source.
Determined by The second analog input value and status.

source.
Determined by The third analog input value and status.
supplying block or
source.
None The value used for the input whenever IN
is below range.
None Sets the options for using IN, IN_LO, IN_1,
IN_2, and IN_3 when any are either Bad or
Uncertain.
None The mode record of the block. MODE
contains the actual, target, permitted, and
normal modes. In some function blocks,
this parameter is used to request and
show the source of the setpoint, the
source of the output, and/or the block
operating state.
EU of OUT_SCALE or The analog output value and status. The
Percent or EU of IN number of outputs is an extensible
parameter in some blocks.
EU of OUT_SCALE The maximum output value allowed.
supplied by IN
EU of OUT_RANGE The minimum output value allowed.
