5.3 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 the analog input channel, and programming in STEP 7
The method to use for the various analog modules is module-specific, and described in detail
in the relevant module chapters.
The next chapter shows how to set the measuring method and range using measuring range
modules.
Setting the measuring method and range using measuring range module
Analog modules are supplied with measuring range modules as required.
Reposition the measuring range modules to suit the measuring method and range.
Note
The measuring range modules are attached to the side of the analog input module.
Before you install the analog input module, check the measuring method and range of the
measuring range modules, and adapt these as required.
Optional settings of the measuring range modules
Optional settings of the measuring range modules are: "A", "B", "C" and "D".
For detailed information on specific measuring method and range settings, refer to the
relevant module chapter.
The settings for the various measuring methods and ranges are also shown on the printed
label of the analog module.
