Product Overview Release 11/02

1.1 Advantages of the Computer Unit

Computer unit

The computer unit is the basic component both for the PC-based HMI devices
(Panel PC) and (in special configurations) and for custom-configured devices.

The computer unit is intended for use in industry as well as in the residential,
business and commercial areas and can also be used in building system
automation or in public facilities, in addition to industrial applications.

The computer unit is an especially high-performance industrial PC designed in
Celeron/Pentium III technology.

Features

The computer unit is characterized by:

S extensive climatic, vibration and shock tests to ensure industrial compatibility;
S electromagnetic compatibility conforming to CE and FCC;
S UL/CSA approvals;
S user support by hotline, service, spare parts;
S quality assurance conforming to ISO 9001;
S compliance with the requirements for a fire enclosure to EN60950/UL1950 – in

other words, it may be used without an additional fire enclosure;

S flexible expansion capability
S suitability for use in a wide ambient temperature range;
S a design that is easy to service and maintain.

Software equipment

The computer unit is equipped with software which allows it to be used universally.
It includes a standard Windows operating system.

The computer unit additionally allows the use of:

S SIMATIC supplementary software
S software from the entire world of automation

S software from the PC world

SIMATIC Panel PC 870 Computing Unit, Equipment Manual

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,

Product Overview

– 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.

Advantages of the computer unit

S The computer unit is rugged in design and its functions make it particularly

suitable for use on site under harsh industrial conditions. It meets the specific
requirements of an industrial environment, such as noise immunity, compliance
with standards, ruggedness and continuous operation.

S Owing to the variable operating location and the many options for installation,

the computer unit can be used virtually anywhere.

S The computer unit includes all ports and interfaces required for automation with

SIMATIC. These particularly relate to:

1.2 Safety Notes

Caution

!

Notes on installation

Please observe the safety notes on the back of the cover of this manual. The
SIMATIC Panel PC 870 should only be expanded after having read the information
in Chapter 4 and the relevant safety notes.

This device complies with the applicable safety requirements in accordance with
IEC, VDE, EN, UL and CSA. If you have doubts about the approval of the
installation in the intended location, please contact the service representative
responsible for your area.

If the device is brought to its operating location from a cold environment,
condensation may occur. Before starting up, the device must be dry and, therefore,
an acclimatization period of at least 12 hours is necessary.

Product Overview

Before installing and operating the device, please note the information on ambient
conditions in the Appendix A “Technical Data” and on installing the device in
Chapter 2. The device must be installed in such a way that it presents no danger of
any kind (for example, by tipping over).

Ensure that the air vents are not obstructed and sufficient cooling air can be drawn
in inside the device.

Warning

!

When assembling the systems, it is essential to maintain the permissible
installation positions and angles (refer to Chapter 2).

If systems are installed at a non-approved installation location, the approvals to
UL 1950 , UL 508 and EN60950 are no longer valid!

Mains supply

Lay the cables so that no one can step on or trip over them. When connecting the
device, carefully study the pertinent information given in Chapter 2.

Never connect or disconnect power cables or data transmission lines during a
thunderstorm.

In an emergency situation (for instance, damage to the housing, controls or power
cable, penetration by liquids or foreign bodies), pull the power plug and contact the
authorized service department.

The SIMATIC Panel PC 870 must be switched off before connecting/disconnecting
periphery units (keyboard, mouse, printer, etc.). Failure to do so can result in
damage to the PC.

Notes for devices with AC power supply

The device is intended for connection to grounded power supply systems
(TN networks to VDE 0100, Part 300, or IEC 364-3).

No provision is made for connection to non-grounded or impedance-grounded
power supply systems (IT networks).

The power cable should comply with the safety guidelines of the country
concerned.

Check to make sure that the rated voltage for the device coincides with that of the
local mains voltage.

This device is equipped with a safety-tested power supply cable and may be
connected only to a socket outlet with grounding contact.

Make sure that the socket outlet on the device or the socket outlet with grounding
contact of the building wiring system is freely accessible and located as near to the
device as possible.

To completely disconnect the PC from the mains power supply, you must pull the
plug. This connection must be easily accessible. If the PC is to be installed in a
cabinet, a central disconnector must be provided.

Note for devices with DC power supply

The mains power adapter area of the device does not fulfill the requirements of
fireproof housing complying to EN60950; therefore, the assembly configuration in
this area must fulfill the requirements of a fireproof housing.

1-6

Warning

!

The unit may only be connected to a 24 VDC mains power outlet which complies
to the requirements of SELV (Safety Extra-Low Voltage); a grounding conductor
must also be connected.

The cable cross-section must be adapted to the short circuit current of the 24 VDC
power source so that no damage is caused by the cable in the event of a short
circuit. Cable with a cross-section of up to 5 mm2 can be connected.
