Parameter assignment/addressing 4.4 Declaration of parameters


Note

Unused channels

"Disable" unused channels in the parameter assignment to improve the cycle time of the module.

A disabled channel always returns the value 7FFFH.

4.4 Declaration of parameters

Diagnostics missing supply voltage L+ Enabling of the diagnostic message for missing or insufficient supply voltage L+.

Diagnostics short-circuit to ground Enabling of the diagnostics in the event of a short-circuit of the sensor supply to ground or of an input to the sensor supply.

Diagnostics overflow Enabling of the diagnostics if the measured value exceeds the over range.

Diagnostics underflow Enabling of the diagnostics when the measured value falls below the under range.

Diagnostics wire break Enabling of the diagnostics if the module has no current flow and/or the current is too weak for the measurement at the corresponding parameterized input.

The wire break and underflow diagnostics can be activated simultaneously. If both diagnostics occur simultaneously, however, the wire break diagnostics suppresses the underflow diagnostics. Wire break is output as the diagnostics.

Parameter assignment/addressing 4.4 Declaration of parameters


Smoothing The individual measurements are smoothed using digital filtering. The smoothing can be set in 4 stages, whereby the smoothing factor k multiplied by the cycle time of the I/O module corresponds to the time constant of the smoothing filter. The larger the smoothing, the larger the time constant of the filter.

The following image shows the step response for the different smoothing factors depending on the number of module cycles.

Figure 4-1 Smoothing with AI 4×I 2-/4-wire ST

Interference frequency suppression Suppressed by analog input modules, the interferences that are caused by the frequency of the AC voltage network.

The frequency of AC network may corrupt measurements, particularly in the low voltage ranges, and when thermocouples are being used. For this parameter, the user defines the mains frequency prevailing on his system.

BaseUnit with incoming supply voltage Specifies whether the I/O module is located on a BaseUnit with incoming supply voltage (see system manual ET 200SP Distributed I/O System (http://support.automation.siemens.com/WW/view/en/58649293)).

Load voltage missing 17D Missing or insufficient supply voltage L + Check supply voltage L+ on BaseUnit

* Short-circuit of the sensor supply to ground and/or of the input signal to the sensor supply of a channel can have a temporary effect on other channels (duration < 0.5 s). Thus the short-circuit diagnostics can also be reported for unaffected channels and/or the measured value can be affected temporarily.
