10.3 Influence of the range of values
Influence of analog signal on input value
The response of the I/O devices with analog inputs depends on the position of the input
values within the range of values. The table below shows this dependency.
The measured value lies
Within the nominal range
Within the overrange/underrange
Within the overflow
Within the underflow
Before parameter assignment
Within an incorrect parameter assign­
ment 2
Within an incorrect initial parameter
assignment
1 If the the group diagnostics and measuring range parameters are enabled for the input device.
2
If a channel was previously parameterized correctly, it continues running with the last parameters.
Influence of output value on analog output
The response of I/O devices with analog outputs depends on the position of the input values
within the range of values. The table below shows this dependency.
The output value lies
Within the nominal range
Within the overrange/underrange
Within the overflow
Within the underflow
