Parameters of the Measuring-Transducer Channels.
The fast measuring-transducer channels can be configured either as current or as voltage inputs. Apart from
this, their function corresponds to the basic function of the 20-mA-channels (see chapter 5.7.3.5 20-mA
Channel).
Application and Setting Notes
Parameter: TD input-signal type
•
Default setting (_:101) TD input-signal type = Current input
With the parameterTD input-signal type you determine whether the measuring-transducer input
channel works as a Current input or as a Voltage input.
Make sure that the selected channel has also been wired correctly (see Hardware manual, Input and Output
Module IO212).
Parameter: Unit
•
Default setting (_:103) Unit = A
With the parameter Unit, you set the physical unit of measurement of the measured values. The possible
setting values are listed in the settings table.
Parameter: Measuring window
•
Default setting (_:142) Measuring window = 10 ms
With the parameter Measuring window, you set the measuring window that is used to determine the arith-
metic mean value from the sampled values. In case of slowly varying signals, Siemens recommends setting the
top value to 100 ms. With this value, a new, current measured value is provided every 100 ms for further
processing.
