Safety Information for the User
VIPA modules make use of highly integrated components in MOS-
technology. These components are extremely sensitive to over-voltages
that may occur during electrostatic discharges.
Electrostatically sensitive equipment!
The symbol at the left is attached to modules that can be destroyed by
electrostatic discharges.
The symbol is located on the module, the module rack or on packing
material and it indicates the presence of electrostatically sensitive
equipment.
It is possible that electrostatically sensitive equipment is destroyed by
energies and voltages that are far less than the human threshold of
perception. These voltages may occur where persons do not discharge
themselves before handling electrostatically sensitive modules and they
may damage components thereby causing the module to become
inoperable or unusable.
Modules that have been damaged by electrostatic discharge are usually
not detected immediately. The respective failure may become apparent
after a period of operation.
Components damaged by electrostatic discharges can fail after a
temperature change, mechanical shock or changes in the electrical load.
Only the consistent implementation of protective devices and meticulous
attention to the applicable rules and regulations for handling the respective
equipment is able to prevent failures of electrostatically sensitive modules.

Please ship the modules exclusively in the original packing material.
Additionally you may cover the shipping-ready modules with a conductive
package. Conductive packages are anti-static foils or metallized plastic
boxes.
When you are executing measurements on electrostatically sensitive
modules you should take the following precautions:
• Floating instruments must be discharged before use.
• Instruments must be grounded.
You should only use soldering irons with grounded tips when making
modifications on electrostatically sensitive modules.
Attention!
Personnel and instruments should be grounded when working on electro-
statically sensitive modules.

Overview PC-CPU 486
The PC-CPU 486 is a complete compact PC-AT with the power of a 486-
DX processor. On the internal 8MByte Flash-ROM the operating system
MS-DOS 6.22 has been preinstalled.
Beside the plug for keyboard, monitor resp. TFT display, the PC-CPU 486
includes an optional Profibus master. The project engineering of the DP
master takes place via WinNCS from VIPA, the access via C-functions.
Further on, the PC has an internal plug-in location for Hilscher COM
modules.
For the external storage of data, the PC has an CompactFlash-slot Type II
at the front side. Here you may plug in CompactFlashcards resp. hard
discs like e.g. the IBM Microdrive with a storage capacity up to 1GByte.
At this time the PC-CPU 486 is available in the following 2 variants:
• PC-CPU 486 (VIPA 486-1BA00)
with 32MB RAM, 8MB Flash-ROM (DiskOnChip),
Plug-in locations for: Type II CompactFlashand Hilscher COM module
Connections: Mouse, keyboard, DVI jack, interface for communication
and diagnosis at deployment of a Hilscher COM module
• PC-CPU 486 DPM (VIPA 486-1BM00)
Like PC-CPU 486 additionally with integrated Profibus-DP master.
If nothing else is mentioned, the information in this manual refers to
the basic version PC-CPU 486.
There are the following possibilities for deploying the PC-CPU 486 under
Profibus:
• At deployment of the PC-CPU 486DPM, the communication takes place
via a Dualport-RAM. The project engineering is by means of WinNCS
from VIPA and the access at PC side via C-functions.
The DP master allows you to connect up to 125 Profibus-DP slaves to
the PC. The master communicates with the slaves and provides the
data for the PC via the Dualport-RAM. During this operation there may
occur a maximum of 1024Byte data for in- and output.
• You deploy the PC-CPU 486 with a Profibus plug-in card at the COM
module plug-in location. Then access and the project engineering takes
place via the software added to the card.
• Operating temperature: 0... +55°C
• Storage temperature: -20... +65°C
• Relative humidity: 95% short time, 55% average, without condensation
• fan-less operation

General
The PC-CPU 486 is meant for the deployment in the S7-400 from Siemens
and is included to your system via the STEP®7 manager from Siemens. For
periphery and CPU communication an ANSI-C library is in the
consignment.
For storing the operating system the PC provides an bootable DiskOnChip®
disk drive (DOC). The Flash-based disk drive has a size of 8MB. The
deployment of the disk drive and the booting sequence is to fix at the
BIOS.
For the external storage of projects with greater data amount there is a
plug-in location at the frontside for CompactFlash®storage modules
Type II. Only the PC has access rights to the storage modules.
CompactFlash®storage modules are available at VIPA.
For the flexible connection to fieldbus systems the PC provides an internal
plug-in location for COM modules from the Hilscher company.
At the PC you will also find fieldbus, diagnosis jacks and LEDs, that are
automatically controlled by the COM module.
At deployment of a PC-CPU 486DPM is a DP master integrated. The
communication between PC and DP master happens via Dualport-RAM.
You configure the DP master via WinNCS from VIPA and access it from
the PC via C-functions.
Properties

Components
At the frontside of the PC there are different LEDs serving the program
status monitoring. The usage and the according colors of these diagnostic
LEDs are to find in the following table.
Pos. Label Color Description
PC
1 PC-RN green PC is in RUN
2 PC-ST red PC is in STOP
Profibus DP master
3 DP-DE yellow DE (Data exchange) shows communication via
Profibus.
4 DP-RN green If only DP-RN is on, the DP master is in RUN.
The slaves are called and the outputs are 0
("clear" state).
With DP-RN+DP-DE on, the master is in
"operate" state. It changes data with the slaves.
5 DP-ER red Flashes at slave failure (Error)
6 DP-IF red Profibus DP master is signalizing an initiali-
zation error at wrong parameterization.
COM module
7 F-RN green COM module is in RUN
8 F-RD green COM module shows READY
9 F-ER red COM module shows error
10 F-S yellow COM module shows status
At this plug-in location you may insert a CompactFlashâmemory card Type
I+II. The PC includes the card as hard disk in the system. The deployment
of a CompactFlashâcard has to be set in the BIOS.
Together with a CompactFlashâadapter the memory card gets compatible
to the "big" PCMCIA Type II format. Thus you may exchange data with all
PCs via the PCMCIA slot.
Note!
The memory card may only be plugged in resp. out when the Pchas been
shut down!
