1 Automation task
Here you find information on &
the automation task discussed in the documentation on hand.
1.1 Overview
Introduction
Your customer has different plant components, which can be operated and
parameterized using several operator panels.
Depending on whether the station has to be operated, maintained or
parameterized, different user authorizations are required.
Until now, user log-on to the operator panel has been carried out by
entering the user name and the corresponding password manually.
It is intended to replace this log-on type by a chip card that is read out by a
card reader.

Overview of the automation task
The figure below provides an overview of the automation task.
Figure 1-1
Description of the automation task
The operator logs on to the operator panel with a transponder using a card
reader.
This log-on is active only as long as a transponder is plugged into the card
reader.
If the transponder is removed from the card reader, the user is
automatically logged off.
The user data is evaluated by the operator panel and its user
administration.
An authorized person can read the transponder data (user and password),
change them and rewrite empty transponders using a separate system
view.
The operator panels and the  card reader are connected to an S7-300
controller via a PROFIBUS connection.

Automation solution
User log-on to the operator panel via RFID Article ID: 26481978
PLC controller:
A CPU 315-2DP is used as a controller.
The data exchange between operator panels and write/read devices (EKS
electronic key adapter) is performed via the controller.
PROFIBUS network:
All components such as operator panels, write/read devices (EKS
electronic key adapter) and the S7 controller communicate via this
PROFIBUS connection .
2.2 Description of the core functionality
The core piece of this application is the creation of an example illustrating
how to perform a user log-on to an operator panel via the RFID system by
EUCHNER.
If an electronic key read/write (transponder) is inserted into the electronic
key adapter (write/read device), the data is evaluated in the S7 controller
via the I/O module and transmitted to the corresponding operator panel.
The evaluation of the user data (user name and password) is performed on
the operator panel.
If the data sent comply with the data stored in the user administration, the
log-on to the operator panel is successful. Otherwise, the log-on is rejected
with a system message.
2.3 Advantages and benefits of the application
" Errors when entering user name and password can thus be avoided.
" Quick and easy handling.
" Easy log-on even under unfavourable working conditions, for example,
when wearing working gloves.
" High flexibility (e.g., changing user data).

Function Principles and Program Structures
Content
This part discusses the detailed function processes of the hardware and
software components involved, the solution structures, and - where useful -
the concrete implementation of this application.
You only need this part if you want to learn more about the interaction of
the solution components.
3 General Function Mechanisms
Here you find information on &
general function mechanisms concerning the data exchange between the
electronic key adapter by EUCHNER, the operator panels and STEP 7.
3.1 Electronic key adapter
The electronic key adapter is used to read out the electronic key read/write.
The electronic key adapter is integrated into the STEP 7 hardware using a
special GSD file.
Note
The GSD file can be downloaded from the EUCHNER home page.
The data exchange between the electronic key adapter and the STEP 7
program is performed via a specified I/O area.
The PROFIBUS address is set on the electronic key adapter via a DIP
switch.
3.2 Electronic key read/write
The electronic key read/write features a user-programmable memory area.
This memory area is written and read out using STEP 7 program blocks.
3.3 Operator panel(s)
The user administration is created in the configuration and transferred with
the configuration to the operator panels.
Corresponding user rights are assigned to variables and buttons that can
only be executed by the user with the appropriate authorizations.
When executing a password-protected function, a dialog box is displayed
where the user can enter a user name and a password.
This log-on procedure via the  log-on dialog is supplemented /replaced by
previously reading out the RFID data via the electronic key adapter.

Function Principles and Program Structures
General Function Mechanisms
User log-on to the operator panel via RFID Article ID: 26481978
The STEP 7 program evaluates the data of the electronic key read/write,
processes them and sends the data (user data) to the operator panel.
There, an internal function evaluates whether the operator has the required
authorization.
Note
By means of the user administration stored, the operator panel compares
whether the user data read out is correct.
The user data is not stored in the controller.
3.4 STEP 7 Program
The STEP 7 program accesses the I/O data of the electronic key adapter.
The write/read area is assigned to the respective data block. The further
evaluation is then performed using these data blocks.
" You can download a special manual from the EUCHNER home page, which
Notes
provides you with information on the EKS electronic key adapter with a
PROFIBUS-DP interface.
This manual contains detailed information on how to parameterize the
electronic key adapter. (www.euchner.de)
(See also Chapter 9.1 Bibliographic references)
" There are two previously parameterized data blocks for the write/read area
that are used for communication.
The blocks can be adapted accordingly by the user.

4.3 Description of program execution FC15
(Pan_01_EKS_Evaluation)
The FC15 program block contains the program for evaluating the EKS
electronic key adapter for the operator panel 01 (MP277 Touch).
The figure below provides a schematic overview of the EKS data
evaluation.
Figure 4-3
Reading out the key data
The output area of the electronic key adapter is used to read out the
output data via the SFC14 and assign them to the DB150DBX...
The data read out is split into two string variables and assigned to the
DB153DBX... via the SFC20 .
The reason for this is that the string variable read out (DB150DBX...)
consists of an  overall text .
This  overall text must be split into  user name and  password for
evaluation. This is done using the SFC20.
The  result is then written to the DB153DBX... and output on the
operator panel.
Writing data to the key
The two string variables DB153.DBX... can be used to specify the user
name and the password via the operator panel.
The two string variables are combined to one string variable via the SFC20
and assigned to the DB151.DBX... This string variable is assigned to the
input area of the electronic key adapter via the SFC15 and written to the
electronic key read/write.

4.3.1 Structure of the DB150 and DB151 blocks
The DB150 and DB151 are data blocks that have been previously
parameterized by EUCHNER. These data blocks are used for data
exchange between the S7 controller and the electronic key adapter.
The data blocks can be adapted to the specific user requirements. One
data block with the structures of the DB150/DB151 is required for each
EKS electronic key adapter.
Copy the DB150/DB151 for this purpose and rename them accordingly.
Notes
" Detailed information, for example, on the  status byte is available
in the EKS manual  Electronic-Key Adapter with Profibus-DP

4.3.5 Program description NW 6 of the FC15
Network 6 is used to read out the contents of the electronic key read/write
(user name and password) via the DB150.
To enable the user data to be read out and evaluated via the corresponding
I/O fields (string variables), the contents of the electronic key read/write
(DB150) have to be split into two separate string variables (DB153).

4.3.8 Program description NW 9 of the FC15
A delay time can be set in network 9 to delay the  Log-on function on the
operator panel.
The  DB150.DBX0.1 bit is used to determine whether a transponder is
present in the read/write device. (See also Chapter 4.3.1  DB150
structure, status byte)
Background:
If the electronic key read/write is inserted in the electronic key adapter, the
contents of the electronic key read/write are first read out via the
S7 controller.
This data is then transmitted to the operator panel to the parameters of the
 Log-on function.
This parameter transmission (user name and password) must be
completed first before the  Log-on function is executed on the operator
panel.
Note
If the selected time is too short, it is possible that the user will not be able
to log on.
The delay time depends on the CPU cycle time and the communication
load on the PROFIBUS.
500ms are set by default.

Network 10 is used for the operator panel  log-on and log-off .
Figure 4-13
The DB15.DBW16  auxiliary variable is used to execute the  log-on and
log-off function on the operator panel.
If the electronic key read/write is inserted and the T15 delay time expired
(see NW9), value  2 is assigned to the DB15.DBW16 variable.
As soon as the electronic key read/write is removed from the electronic key
adapter (evaluation is performed via the DB150.DBX0.1 bit), value  -1 is
assigned to the  DB15.DBW16 variable.
Background:
The following limits have been assigned to the DB15.DBW16 variable in the
WinCC flexible configuration:
" Upper limit:  1
" Lower limit:  0
Under  Events :
" Upper limit exceeded ->  Log-on function assigned
" Lower limit fallen below ->  Log-off function assigned.
Thus, the  log-on function is automatically executed if the limit is exceeded
and the  log-off function if the limit is fallen below.
(depending on whether an electronic key read/write is inserted in the
electronic key adapter)

If the controller detects that an electronic key read/write is provided in the
electronic key adapter, value  2 is entered into the DB15.DBW16 variable
via the controller (see also Chapter 4.3.9).
The  limit value monitoring is used to execute the  log-on function via
the  Upper limit exceeded event.
If the electronic key read/write is removed from the electronic key adapter
again, value  -1 is entered into the DB15.DB16 variables via the controller
(see also Chapter 4.3.9).
The  limit value fallen below is used to execute the  log-off function via
the  Lower limit fallen below event.
Note
The following settings must be taken into account for the DB15.DBW16
variable used. (Properties > General).
" Acquisition mode: Cyclically continued
