Release 11/02
Additional applications:
The computer unit can also be used in other areas of automation engineering
(SIMATIC HMI; TELEPERM; SINUMERIK; SIROTEC, etc.).
Installation
The computer unit can be installed in various installation locations (refer to
Chapter 2.2).
There are anchorage points on both of the longs sides for securing the computer
unit. Mounting brackets are screwed onto these anchorage points.
Decentralized design
A decentralized design is possible as an alternative to a centralized configuration.
The advantages are that
– The operating unit can be installed closer to the machine and inclined at an
angle of up to 70 ° for example, in a swivel arm ("boom") or console,
– The more sensitive computer unit (hard disk) can be installed vertically some
distance away from the machine where vibration is low – for example, in a
cabinet.
With this configuration, additional components are included for communication
between the operating unit and computer unit:
– the host module, which is mounted on the computer unit,
– the remote module, which is mounted on the operating unit and
– the cable, which links them.
This equipment manual is organized as follows.
S Chapters 2 to 7 basically describe the specific characteristics of the
computer unit in a centralized design, making reference, where necessary,
to the complete unit, e.g. with regard to the dimensions for mounting,
maintenance and technical specifications.
S Chapter 8 describes the decentralized design of the Panel PC.
