The "Busy" (object specific General Error code 0xD0) error response may be
returned if the Auto_Range service cannot be completed successfully.
Device Mode Object
(Class ID 320
H
)
The Device Mode Object is used to control access to the configuration
parameters in the module. This object’s Device Mode attribute must be in
PROGRAM mode to allow the module’s configuration parameters to be "Set"
(see Services). Attempts to set the configuration parameters while the Device
Mode is in RUN mode will return an error. Note that the module collects
measurements while in RUN mode but not while it is in PROGRAM mode.
Class Attributes
The Device Mode Object provides no class attributes.
Table C.35 Auto_Range Request Parameters

Description of Request
Parameters
Semantics of Values
Safety Factor REAL Specifies a multiple that, when
applied to the current signal level,
determines the maximum signal
level that must be handled by the
hardware. Must be greater than or equal to 1.0.

Parameters
Semantics of Values
Full Scale REAL The new Full Scale value. Specifies the maximum signal level expected
to be processes by the channel. This value is
used to determine the analog hardware range
when the hardware supports programmable
gain settings. Setting the Full Scale to a
greater value allows the channel to handle
greater input signals without saturating or
clipping. Setting Full Scale to a lesser value
allows the signal to be measured with greater
resolution. The units of the Full Scale value is
Volts peak.
