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
