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.

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

Operating modes of a CPU
These CPUs are intended for small and medium sized applications and are
supplied with an integrated 24V power supply. The CPU contains a
standard processor with internal program memory. In combination with the
System 82xx peripherals the unit provides a powerful solution for process
automation applications within the System 82xx family.
A CPU supports the following modes of operation:
• cyclic processing
• timer processing
• alarm controlled processing
• priority based processing
Cyclic processing represents the major portion of all the processes that are
executed in the CPU. Identical sequences of operations are repeated in a
never ending cycle.
Where a process requires control signals at constant intervals you can initiate
certain operations based upon a timer, e.g. not critical monitoring functions
at one-second intervals.
If a process signal requires a quick response you would allocate this signal
to an alarm controlled procedure. An alarm may activate a procedure in
your program.
The above processes are handled by the CPU in accordance with their
priority. Since a timer or an alarm event requires a quick reaction the CPU
will interrupt the cyclic processing when these high-priority events occur to
react to the event. Cyclic processing will resume once the reaction has
been processed. This means that cyclic processing has the lowest priority.

CPU 821x programs
The program that is present in every CPU is divided as follows:
• System routine
• User program
The system routine organizes all those functions and procedures of the
CPU that are not related to a specific control application.
This consists of all the functions that are required for the processing of a
specific control application. The operating modules provide the interfaces to
the system routines.
CPU 821x operands
The following operands are available for programming the CPU 821x:
• Process image and periphery
• Bit memory/marker
• Timers and counters
• Data blocks
The user program can quickly access the process image of the inputs and
outputs PAA/PAE. You may manipulate the following types of data:
- individual bits
- bytes
- words
- double words
You may also gain direct access to peripheral modules via the bus from
your user program. The following types of data are available:

Bit memory is an area of memory that is accessible to the user program by
means of certain operations. Bit memory is intended to store frequently
used working data.
You may access the following types of data:
- individual bits
- bytes
- words
- double words
With your program you may load a time cell with a value between 10ms and
9990s. As soon as the user program executes a start operation the value of
this timer is decremented by the interval that you have specified until it
reaches zero.
You may load counter cells with an initial value (max. 999) and increment
or decrement this when required.
A data block contains constants or variables in form of bytes, words or
double words. You may always access the current data block by means of
operands.
