Designated use
Function block SPC200−PC" serves for reading and writing
parameters of the SPC200 from a Simatic S7 controller with
PROFIBUS. For this purpose it uses the SPC200 parameter
channel (PC = parameter channel). The SPC200 must be
connected to the S7 by means of field bus module type
SPC200−COM−PDP.
Basic components and modules for the SPC200 are described
in the user manual type P.BE−SPC200−... . The safety
instructions specified in the manuals must always be
observed and the relevant components and modules must
only be used as intended. Please observe also the safety
instructions listed in the operating instructions for the
pneumatic components used. The SPC200 and the modules
and cables to be connected are only to be used as follows:
inaccordance with designated use
 only in industrial applications
 without any modifications by the user. Only the conver
sions or modifications described in the documentation
supplied with the product are permitted.
infaultless technical condition.
When used together with commercially available compo
nents, such as sensors and actuators, the specified limits for
pressures, temperatures, electrical data, torques etc. must be
observed. National and local safety regulations must also be
observed.
Note also the Siemens specifications regarding the use of
their PLC Simatic S7.

Basic principles of programmed software
Please note that it is not possible with the present state of
technology to create programmed software which functions
without problems and is compatible with all applications and
combinations intended by the user.
As a rule the software must therefore be used in the desig
nated manner as specified in the program description and in
the user instructions.
At the moment when the software is transferred or made
available, it is in a state in which it will function under normal
operating and application conditions.
Festo does not guarantee that the software will suffice for all
applications and purposes intended by the user, or that it will
function without problems when used with other programs,
or that it is compatible with these programs. The responsibil
ity for the correct selection and the consequences of using
the software within the scope of use defined by the user, as
well as for the intended and achieved results therefore lies
with the user. The same applies to the written material sup
plied with the software.
The use of the programmed software does not exempt you as
customer from your duties and responsibility for observing
and adhering to technical machine and safety regulations as
well as for a comprehensive functional check.
Target group
This manual is intended exclusively for technicians trained in
control and automation technology, who have experience in
installing, commissioning, programming and diagnosing
PROFIBUS−DP slaves.

1.1 Incorporating the function block in your project
Step 1
·Install a SPC200 in the Hardware Manager and incorpor
ate the parameter channel in the I/O configuration.
Step 2
·Dearchivate the project which contains the function block.
In order to do this, you must select the menu item [File]
[Dearchivate] in the Simatic Manager and specify the
zip−file:
 FB1_PKW.ZIP
Please note
Always use the Dearchivate" function of the Simatic
Manager in order to expand the zip−file.
Step 3
·Open the FB1_PKW project. Select the FB1 SPC200−PC"
in the folder Blocks" and copy it with [Edit] [Copy].
Step 4
·Change your project and paste the function block. If there
is already an FB1 in your project, you must assign a
different function block number to the function block
SPC200−PC.

1. Installation of the function block
1−4 Festo P.BE−SPC200−S7−PC−EN en 0609a
Step 5
·If this is not yet the case, add also the system function
blocks SFC14 and SFC15 to your project. These are
required by function block SPC200−PC.
Step 6
·Add the access to the FB1 to your sequence program. In
order to do this, you must specify an instance data block.
As this is not yet available, the STEP 7 software askes
whether this should be created. You must confirm this
question.
Caution
You require for one SPC200 only one instance data block.
With this instance data block all axes of the SPC200 can be
addressed.
For each additional SPC200 in the network you will require
another instance data block.
Rule:
Each PKW I/O module in the Hardware Manager requires one
intance data block.

2.1 Symbolic representation of the function block
Fig.2/1: Symbolic representation
The function block is created in LAD/FBD, but contains STL
elements. If you open the function block, please use the
representation FBD or LAD.
2.2 Working method
The function block has been designed asynchronously, i.e.
the processing of a read or write request covers several
accesses. By means of the input parameters, the function
block encodes the request in accordance with the PKW
protocol and transfers it to the SPC200 using the SFC15
DPWR_DAT" or SFC14 DPRD_DAT".
The reply received is transferred to the function block out
puts. When the transfer is finished, DONE=TRUE will be set.

2.3 Input parameters
Parameter Declaration Data
type
Memory
range
Description
Start INPUT BOOL I, Q, M, L, D,
Constant
Start transferring parameter value.
A rising edge 0 −−> 1 causes the input para
meters to be accepted and thereby triggers
the transfer of the parameter.
Prerequisites:
Done = TRUE and Error = FALSE.
Reset INPUT BOOL I, Q, M, L, D,
Constant
Resetting a fault
If there is a fault, a rising edge will cause all
internal data, as well as the output word and
the fault to be reset. If there is no fault, the
signal edge will be ignored.
LADDR_E INPUT WORD I, Q, M, L, D,
Constant
Planned starting address from the process
image input area of the PKW module of the
SPC200
 The address must be entered in hexadeci
mal form: Starting address 256:
LADDR_E:=W#16#100.
 LADDR_E and LADDR_A can but need not
have the same address.
LADDR_A INPUT WORD I, Q, M, L, D,
Constant
Planned starting address from the process
image output area of the PKW module of the
SPC200 (see LADDR_E).
RD_WR INPUT BOOL I, Q, M, L, D,
Constant
Defines whether the parameter is to be read
or written.
0 = The parameter is read out of the
SPC200.
1 = The parameter is written into the
SPC200.
PNU INPUT INT I, Q, M, L, D,
Constant
Selected parameter number.
Available parameters see manual for the field
bus module SPC200−COM−PDP.
