Safety information for users
ADAM modules make use of highly integrated components in MOS-
technology. These components are extremely sensitive to over-voltages
that may occur during electrostatic discharges.
The following symbol 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.
When you are conducting 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 you are
making modifications on electrostatically sensitive modules.
Attention!
Personnel and instruments should be grounded when working on
electrostatically sensitive modules.

ADAM 8000 Manual CPU 821x – Rev 1.1 1-3
Hints for the deployment of the MPI interface
The MP2I jack combines 2 interfaces in 1:
• MP interface
• RS232 interface
Please regard that the RS232 functionality is only available by using the
Green Cable from Advantech.
The MP interface provides the data transfer between CPUs and PCs. In a
bus communication you may transfer programs and data between the
CPUs interconnected via MPI.
Connecting a common MPI cable, the MPI jack supports the full MPI
functionality.
Important notes for the deployment of MPI cables!
Deploying MPI cables at the ADAM CPUs from Advantech, you have to
make sure that Pin 1 is not connected. This may cause transfer problems
and in some cases damage the CPU!
Especially Profibus cables from Siemens, like e.g. the 6XV1 830-1CH30,
must not be deployed at MP2I jack.
For damages caused by nonobservance of these notes and at improper
deployment, ADAM does not take liability!
For the serial data transfer from your PC, you normally need a MPI
transducer. Fortunately you may also use the "Green Cable" from
Advantech You can order this under the order no. ADAM-8950-0KB00.
The "Green Cable" supports a serial point-to-point connection for data
transfer via the MP2I jack exclusively for ADAM 8xxx CPUs.
Please regard the hints for the deployment of the "Green Cable" on the
following page.

Hints for the deployment of the Green Cable
The Green Cable is a green connection cable, manufactured exclusively for
the deployment at ADAM System components.
The Green Cable is a programming and download cable for ADM CPUs
8xxx and ADAM fieldbus masters. The Green Cable from Advantech is
available under the order no. ADAM-8950-0KB00.
The Green Cable allows you to:
• transfer projects serial
Avoiding high hardware needs (MPI transducer, etc.) you may realize a
serial point-to-point connection via the Green Cable and the MP2I jack.
This allows you to connect components to your ADAM CPU that are able
to communicate serial via an MPI adapter like e.g. a visualization
system.
• execute firmware updates of the CPUs and fieldbus masters
Via the Green Cable and an upload application you may update the
firmware of all recent CPUs 8xxx and certain fieldbus masters (see
Note).
Important notes for the deployment of the Green Cable
Nonobservance of the following notes may cause damages on system
components.
For damages caused by nonobservance of the following notes and at
improper deployment, Advantech does not take liability!
Note to the application area
The Green Cable may exclusively deployed directly at the concerning jacks
of the ADAM components (in between plugs are not permitted).
At this time, the following components support the Green Cable:
CPUs 8xxx and the fieldbus masters ADAM 8208-1xx01 from Advantech.
Note to the lengthening
The lengthening of the Green Cable with another Green Cable res. The
combination with further MPI cables is not permitted and causes damages
of the connected components!
The Green Cable may only be lengthened with a 1:1 cable (all 9 Pins are
connected 1:1).

Hints for project engineering
For the project engineering of the CPU 821x and the other System 82xx
modules connected to the same bus, you use the hardware configurator
from Siemens.
To address the directly plugged peripheral modules, you have to assign a
special address in the CPU to every one.
The address allocation and the parameterization of the modules takes
place in the STEP7 manager from Siemens in form of a virtual Profibus
system. For the Profibus interface is standardized software sided, the
functionality is guaranteed by including a GSD-file into the STEP7
manager from Siemens.
Transfer your project into the CPU via the MPI interface.
For the project engineering of your CPU 821x the following requirements
have to be fulfilled:
• STEP7 manager from Siemens is installed at your PC resp. PU.
• The GSD-file for the System 82xx is included to the hardware
configurator
• serial connection to the CPU (e.g. via "Green Cable")
Note!
The configuration of the CPU requires a thorough knowledge of the
Siemens STEP7 manager and the hardware configurator!
The CPU 821x is configurable via the STEP7®manager from Siemens.
This means the programming and parameterization of a System ADAM
82xx and the parameterization and project engineering under Profibus-DP.
The project engineering of a CPU 821x takes place via the STEP®7 mana-
ger from Siemens in form of a virtual Profibus system with the CPU 315-
2DP as basic.
Due to the standardized Profibus interface ADAM is able to support the
complete functionality of the System 82xx family in the STEP®7 manager
from Siemens by including a GSD-file.
To be compatible with the STEP7 configuration tool from
Siemens, the following steps have to take place:
• Project the Profibus-DP master system with CPU 315-2DP
(6ES7 315-2AF01).
• Add Profibus slave with address 1.
• Include the CPU 821x at slot 0 of the slave system.

The following steps are necessary to project a CPU 821x in the hardware
configurator from Siemens:
• Start the hardware configurator from Siemens
• Load the delivered ADAM GSD-file from Advantech
• Create a Profibus-DP master system with the CPU 315-2DP
• Include the slave system "ADAM_DP8000" from the hardware catalog in
your master system. You find this slave system in the hardware catalog
under Profibus-DP > Additional field devices > I/O > ADAM
• Assign the address 1 to your slave system, so that the CPU is able to
recognize the system as central periphery system
• Add your modules to the slave system in the same order you have
assembled them. Start with the CPU at plug-in location 0
• Include your System 82xx modules starting at plug-in location 1

When configuring a CPU 821xDP, the central plugged-in modules are
parameterized like shown above.
Slave parameterization
As intelligent slave, the Profibus section maps its data areas into the
memory area of the CPU 821xDP. The assignment of the areas is fixed via
the propierties of the CPU 821xDP. These areas have to be provided with
an according PLC program.
Attention!
The length values of input and output area have to be identical to the byte
values of the master project engineering. Otherwise no Profibus communi-
cation is possible (slave failure).
Steps of project engineering in the DP master
• Configure the CPU with DP master system (address 2)
• Add Profibus slave 821xDP (GSD-file required)
• Assign Profibus input and output area starting with plug-in location 0
