SIMATIC PCS 7 cabinet design

Introduction

Cabinet packaging system

■Overview

The cabinet design for components close to the process (auto- mation systems and I/Os) fulfills the technical and economical demands placed on the AS 488/TM automation systems.

The cabinets consisting of system-specific modules (system and I/O units) and system-neutral modules (basic cabinets and options) comply with CE requirements and conform to the guide- lines for electromagnetic compatibility. They are designed ac- cording to the VGB 4 guidelines, and provide exceptional protection against unauthorized interventions, mechanical ef- fects, contamination and corrosion.

As a result of their variable modular design, the cabinets can be readily adapted to different types of system (for batch processes or continuous processes) and system sizes.

The Siemens standard cabinet 8MC with degree of protection IP 40 is the preferred basic cabinet. Cabinets with degree of protection IP 20 and IP 55 are alternatively available.

Modular design

System-specific modules

•AS 488/TM system unit

•ET 200M I/O unit (ET 200U/ET 200B on request)

System-neutral modules

•Basic cabinet, consisting of framework, door, outer walls, inter- nal mechanical parts and power supply assembly with:

-Compartment for documents

-Trim

-AC 230 V socket

-AC 230 V or DC 24 V cabinet illumination

-I & C monitoring via automation system or cabinet lamp

Options

•Circuit-breaker for protection of max. 6 cabinet tiers

•I/O modules for ET 200M I/O unit

High flexibility

•Future compatibility as result of universal, system-neutral mod- ules

•Modular packaging system permits flexible adaptation to the respective application

•Basic and expansion cabinets based on the same set of mod- ules

•Up to 4 system units or 6 I/O units can be fitted in a cabinet

•System units and I/O units can be combined within the cabinet

•Side walls or partitions can be selected specific to the applica- tion

•Cabinets can be screwed together into double units or rows

•Design supports installation, commissioning, servicing and re- pairs

•Design supports correct handling when replacing modules

•All installation, commissioning, servicing and repair work can be carried out from the front of the cabinet

•Design of power supply assembly: either with Siemens circuit- breakers or with circuit-breakers with monitoring contact for connection to receptacles (from company ETA)

•Wiring for electronics supply as well as load power supply to I/O modules

•Wiring of PROFIBUS-DP either with copper or fiber-optic ca- bles

Consideration of Ex(i)-specific requirements

•The construction of the system and I/O units permits a cabinet design which satisfies the Ex(i)-specific requirements

•Uniform installation and replacement for all I/O modules from the ET 200M range, including Ex(i) modules (plug connection for load power supply above the modules).

Design guidelines

•The SIMATIC S7-300 and S7-400 design guidelines apply when installing the AS 488 in PCS 7 cabinets (only with exclu- sively distributed SIMATIC I/Os).
