Assignments are made with the mouse button. Clicking on the "Type" entry field
opens a selection field containing the following:
n
+/-10 V
Type
The expected input signal varies in a range of (–10 V) to (+10 V).
n
0~10 V
An input signal of from (0 V) to (+10 V) is expected.
n
4~20 mA
The current level of the input signal varies between (4 mA) and (20 mA).
Range The "Range" column is where you enter the signal value range in [%]. A signal of (-
10V) for a range setting of ±100% corresponds to a signal of (-100%).
The relationship is shown in the graphic below
Min The "Min" setting is used to limit the minimum input signal to a value you determine
within the type range (±10 V). For example, a value of (-5 V) means the signal (-5 V) is
interpreted as (-100%) range (see Fig. 41 Analog I/O - Input adjustments).
Max The "Max" setting is the opposite of "Min". For example, a value of (+9 V) means the
signal (+9 V) is interpreted as (+100%) range (see Fig. 41 Analog I/O - Input
adjus tments).
The setting for the value "Min Error" is used to specify the minimum error. When the
signal falls below this entered value, BODAC uses the "Status" window to indicate that
a fault has occurred if the fault is activated in the "Faults" window.
The setting for the value „Max Error" is used to specify the maximum error. When the
signal exceeds this entered value, BODAC uses the "Status" window to indicate that a
fault has occurred if the fault is activated in the "Faults" window.
The "Max Units" setting specifies the value range of the signal in units [Unit].
The following example shows in table and graphic form the parameters for a signal
adjustment in the Inputs field.
