Analog modules

Introduction
This chapter describes:
1. Analog module selection and commissioning sequence
2. Overview of essential module properties
3. Modules which are available (properties, connection and block diagrams, technical data
and additional information on the module):
a) for analog input modules
b) for analog output modules
c) for analog IO modules

blocks for analog functions
You can use FC105 "SCALE" (scale values) and FC106 "UNSCALE" (unscale values)
blocks to read and output analog values in
standard library, in the "TI-S7-Converting Blocks" subfolder.
