SIMATIC PCS 7 cabinet design

Basic cabinet

Overview

The Siemens standard cabinet 8MC is the preferred basic cabi- net. The Siemens standard cabinet 8MC is a sheet-steel cabinet with rear panel and front door which can be assembled individ- ually or also in rows with further cabinets of this type.

Side walls and partitions are optional, thus permitting variable adaptation of the cabinet to different installation possibilities.

Up to four system units or six I/O units can be fitted in a cabinet in conjunction with a DC 24 V or AC 230 V power supply assem- bly. System and I/O units can also be combined together within a cabinet. The cables are introduced into the cabinet from be- low.

Mechanical design

Each delivered cabinet contains:

19-inch mounting frame

Rear panel

Door

Transport lugs

Clips for routing of process cables

Cable duct for cabinet-internal wiring

Options for the mechanical design

When ordering the basic cabinet, the following options are avail- able for the mechanical design of the cabinet:

Plinth: a cabinet plinth should be used if cables cannot be con- nected through the floor. The plinths are preassembled, and available with a height of 100 or 200 mm

Pocket for documents

Trim

Side walls/partitions: the basic cabinets are suitable for individ- ual assembly or in rows. Therefore side walls and/or partitions can be selected when ordering.

Electrical design

Each delivered cabinet contains:

Power supply assembly AC 230 V or DC 24 V

Cable clamps and screen bars for I/O and bus cables

Prewiring of power supply cables for central and I/O units

Wiring of PROFIBUS-DP fieldbus

Connector board for cabinet earth

Options for the electrical design

AC 230 V socket (installed in power supply assembly)

I & C monitoring (2 versions):

-I & C monitoring via cabinet lamp. A blown fuse is signalled by a lamp in the cabinet door. OLM failure can be additionally displayed on the cabinet lamp

or

-I & C monitoring via AS 488/TM and cabinet lamp. Tempera- ture violations in the cabinet, an open door contact, a blown fuse and an OLM failure can be recorded by the IF 961-DIO interface module and additionally signalled by a lamp in the cabinet door

-Single/redundant design of power supply assembly, option- ally with 6 or 14 circuit-breaker receptacles

Cabinet illumination
