5.3 Setting the measuring method and ranges of analog input channels
Two procedures
There are two methods of setting the measuring method and ranges of analog input
channels at analog modules:
● using a measuring range module and
STEP 7
● hardwiring of the analog input channel and STEP 7
The method to use for the various analog modules is module-specific and is described in
detail in the special module chapters.
This section describes how to set up the type and range of measurement using measuring
range modules.
Setting the measurement type and ranges using measuring range modules
The analog modules are supplied with corresponding measuring range modules as required.
You may have to change the position of the measuring range module to suit the
measurement type and range.
Note
Note that the measuring range modules are installed on the side of the analog input module.
Always check whether the measuring range modules needs to
be set up for a different
measurement type and range before
you install the analog input module.
Optional settings of the measuring range modules
Optional settings of the measuring range modules: "A", "B", "C" and "D".
For detailed information on settings to be made for a specific measurement type and range,
refer to the special module chapter.
The settings for the different measurement types and ranges are also printed onto the
analog module.
