Auto (Auto). The block output value is set by the block algorithm, whereby the
block uses a local value as setpoint.
Cascade (Cas).The block setpoint is taken out of the CAS_IN parameter which
is normally connected to the output of another block. Diese Betriebsart kann
erst nach der Kaskaden- Initialisierung verwendet werden. If Cascade shall be
used as Target mode, the Auto Bit within Target is also set.
Remote Cascade (RCas). Like for the Cascade mode, the Remote Cascade
setpoint is supplied by an external data source. Contrary to Cascade, in Remote
Cascade mode the block receives the setpoint from the RCAS-IN parameter
which has been written by a host application and not by another function block.
Remote Output (ROut). The Remote Output mode is identical to the Remote
Cascade mode, except that the host application directly sets the block output
and not the setpoint. Thus, the setpoint range and the absolute limitation is
bypassed for an analogue output block.
Depending on the status of a downstream block or in case of local operation, the
Actual mode of function blocks for Output or Control can take the status IMan
(Initialization Manual) or LO (Local Override).
Only operation modes OOS and AUTO are available for the resource block. The
operation modes OOS, MAN, and AUTO are available for transducer blocks.

Description
Indicates whether the discrete input value should be logically in-
verted before it is stored in the process variable. A discrete value
of zero (0) will be considered to be a logical zero (0) and an non-
zero discrete value will be considered to be a logical (1). When
selecting invert, the PV value is inverted.
Allows the setpoint to track the process variable, if the target
mode of the block is Man.
Allows the setpoint to track the process variable if the actual mode
of the block is LO.
Allows the setpoint to track the RCas or Cas parameters based
on the retained target mode, if the actual mode of the block is
LO or Man. Once SP-PV track options are enabled, the SP track
retain target will have precedence in the selection of the value to
track if the actual mode is Man and LO.
Defines whether the output value should be inverted before it is
communicated to the I/O channel.
Measures to take in the event of a fault (0: freeze value, 1: accept
preset value).
Use the FSTATE_VAL(_D) parameter value, other use the non-
volatile value. The reaction does not depend on the Fault state
function, only the FSTATE_VAL(_D) is used.
Set target mode to Man when enabling the fault state; the initial
target value is lost. This puts the output block in manual mode.
Usually, the BKCAL_OUT value is the active setpoint (SP). This
option changes it to the process variable (PV).
The AI Low Cutoff algorithm is enabled.
Device will perform units conversion on the channel value so that
it will match the units set in XD_SCALE. If the units of XD_SCALE
are set to a value not supported by the device then the block will
remain in O/S after being configured.
