5.1 General information

Structure

This section contains the following topics:

1. Overview of the analog modules available

2. General information concerning all analog modules (such as parameter assignment and

diagnostics)

3. Information that refers to specific modules (for example, features, wiring diagram and

block diagrams, specifications and special characteristics of the module):

a) for analog input modules

b) for analog output modules

STEP 7 blocks for analog functions

You can use blocks FC 105 and FC 106 to read and output analog values in

STEP 7

. You

will find the FCs in the standard library of

STEP 7

in the subdirectory called "S5-S7

Converting Blocks" (for a description refer to the

STEP 7 Online Help

for the FCs).

Further information

The appendix describes the structure of the parameter records (data records 0 and 1) and

diagnostic information (data records 0 and 1) in the system data. You must be familiar with

this configuration if you want to modify the parameters of the modules in the

STEP 7

user

program.

The structure of diagnostic information (data records 0 and 1) is described in the system

data section of the appendix. You must be familiar with this configuration if you want to

evaluate the diagnostic data of the modules in the
