Scalable automation systems, overview

The SIMATIC PCS 7 process control system offers a wide range of automation systems whose performances are finely matched to one another within wide limits. This results in fine scaling of the automation performance over the complete performance range.

The automation systems offered can be differentiated according to various criteria. In accordance with the design, they are cate- gorized as:

•Microbox automation system with software controller

•Modular automation systems of the S7-400 range with hard- ware controller

■Application

Microbox automation system

10	The SIMATIC PCS 7 AS RTX Microbox automation system repre-
	sents the starter system in the lower performance range of

SIMATIC PCS 7. As a result of its exceptional physical properties and small dimensions, it is particularly suitable for use at plant level in industrial applications.

Modular automation systems of the S7-400 range

In these "Automation system bundles", selected components of the SIMATIC S7-400 are combined together.

The following characteristics make the SIMATIC S7-400 predes- tined for use as a SIMATIC PCS 7 automation system:

7Modular design without fans

7High expansion capability and ruggedness

7Single or redundant design

7Comprehensive communication facilities

7Integral system functions

7Integrable safety functions (Safety Integrated)

7Simple linking of central or distributed I/O

In accordance with their functionalities, the modular automation systems of the S7-400 range can be classified into:

•Standard automation systems

•Fault-tolerant automation systems

•Safety-related automation systems

Various automation systems are available with a price/perfor- mance ratio which can be tailored to your system requirements. The CPU of the automation systems is already equipped as stan- dard with an onboard PROFIBUS DP fieldbus connection. Depending on the type of CPU, 1 or 2 further PROFIBUS DP in- terfaces are possible using additional IF 964-DP interface mod- ules. PROFIBUS communication modules can be additionally fit- ted if required.

■Design

Microbox automation system

The compact and rugged automation system based on the SIMATIC Microbox PC 427B has been designed for mainte- nance-free 24-hour continuous operation at ambient tempera- tures up to 55 °C. Since there are no fans or rotating storage me- dia, it is resistant to vibration and shock.

The Windows XP Embedded operating system, the WinAC RTX controller software, and the SIMATIC PC DiagMonitor diagnos- tics software are preinstalled on the supplied 2-GB Compact- Flash card. The scope of delivery also includes an AS runtime license for 250 POs.

Modular automation systems of the S7-400 range

The SIMATIC PCS 7 automation systems of the S7-400 range are delivered as preassembled and tested all-in-one systems (AS bundles) at no extra charge. Each of these AS bundles is already combined with a SIMATIC PCS 7 AS Runtime license for 100 process objects (PO).

The configuration of the AS bundles and their Order Nos. can be individually combined by selecting preconfigured ordering units. System-specific ordering configurations are available for this purpose in the Sections "Standard automation systems", "Fault-tolerant automation systems" and "Safety-related automa- tion systems". In order to facilitate selection of preferred configu- rations, these are additionally listed with their complete Order Nos.

As an alternative to this catalog for ordering the AS bundles, a configurator offered in the catalog & online ordering system "A&D Mall" (www.siemens.com/automation/mall) can also be used.

Depending on the configuration as Single Station or Redundant Station, an AS bundle is equipped with the following compo- nents:

•1 or 2 racks with 9 or 18 slots

•1 or 2 SIMATIC S7-400 CPUs

•1, 2 or 4 PS 405 (24 V DC) or PS 407 (120/230 V AC/DC) power supplies, without backup batteries in each case

•1 or 2 x RAMs from 768 KB to 30 MB

•1 or 2 memory cards with 2 to 16 MB RAM

•1, 2 or 4 interface modules for Industrial Ethernet plant bus (via CP or integrated in CPU)

•Additive PROFIBUS communications processors (by means of configurator up to 4 per Single Station, up to 8 per Redun- dant Station)

•4 sync modules for a range up to 10 m or 10 km and 2 fiber- optic sync cables, 1 m (longer lengths can be ordered sepa- rately)
