Siemens SIMATIC S5-100U System Manual page 24

The SIMATIC S5 System Family
The S5-100U has the following features:
• Modular Design
Depending on the CPU you use, the S5-100U allows you to have a maximum of 448 digital
inputs and outputs. It is suitable for machine control and for process automation and monitoring
on a medium scale. The S5-100U allows a broad expansion capability with various types of
modules to adapt optimally to a control task.
• Rugged, Lightweight Design
All of the modules you can use with the S5-100U are block-type modules that are small, rugged,
and easy to use. The modules operate without fans. None of these modules has electro-
magnetically sensitive electronics. The modules are plugged into bus units and screwed tightly
so that they are vibration-proof.
The bus units snap onto a standard mounting rail. You can configure the S5-100U in one or
more tiers and configure it vertically or horizontally. The S5-100U offers such a wide range of
configuration possibilities that you can use it in rough and difficult operating conditions.
• Simple Programming
The programming language is STEP 5 and its comprehensive operations set. It provides three
different methods of representation, - four, if you have a CPU 103 or higher.
You can use any of the U series programmers to program your S5-100U, or you can load
programs from memory submodules.
