SIMATIC PCS 7 OSx
System
1-4 Hardware Overview
The SIMATIC PCS 7 OSx system consists of the following major
subassemblies.
The System Unit (Model B132L+) controls the scheduling and the
gathering of data from the Industrial Ethernet network. The system unit
makes decisions on what to do with the gathered data based upon the
database configuration. It contains the real time relational database, system
software packages, system RAM memory, and network interface.
The 21-Inch Monitor provides 256 colors and 1280 x 1024 pixel resolution.
The Engineering Keyboard allows you to configure the system, to design
reports, and to program. The engineering keyboard is of standard
construction, but is configured to function like an operator keyboard and
can be used in the Operate state.
The Operator Keyboard allows you to access process graphics and
displays, to enter new values, and to print reports. The operator keyboard is
constructed of a factory-hardened, tactile membrane, with a port that can be
used to link up with a PS/2 mouse or trackball, and a standard engineering
keyboard. Only PS/2 pointing devices are supported by the operator
keyboard.
The Pointing Device (Trackball/Mouse) is used for moving quickly among
the menu and screen-selections, and for drawing shapes in the graphics
editor.
The Magneto-Optical Drive is used for data archiving.
The CD-ROM is used for loading software and for accessing the SIMATIC
PCS 7 OSx manual set.
The Hard Disk Drive serves as the mass storage device for the system
unit. It consists of one 2 Gbyte+ formatted capacity drive.
The Ethernet Communications Board allows the OSx station to be
attached to an Ethernet network.
The S7–200 CPU 212 provides connection to the failover circuit and
external warning and critical alarms.
