System description

The present manual is meant as support in creating a Profibus project under SIEMENS Step7
Software, in establishing communication with the spindle position displays (SPA) and in

troubleshooting of Profibus errors.
Gateway GK473 (interface converter) is connecting the spindle position displays (= SPAs, for
example N 140 / N 142 / N 150) of the Baumer IVO multicon system to a Profibus-DP­capable PLC. By aid of the gateway the data blocks of the SPA’s RS485 interface are
converted into Profibus DP protocol (and vice-versa).
Some individual gateway functions considerably improve and facilitate PLC programming.
The gateway enables a network of max. 32 SPAs connected to Profibus-DP. The gateway can
be applied with all spindle position displays of the multicon family. Furthermore, several
gateways can be operated at a Profibus in order to connect more SPAs.

The Step7 project and function blocks described in this paper were created using a Step7
Software Version 5.0 + ServicePack2 under Windows 98, together with a S7-315-2DP with an
input module DI16xDC24V and an output module DO32xDC24V/0,5A. However, with only
slight modifications, the project should run in most other Windows / Step7 environments as
well.

2. Gateway Settings

As described in the GK473 manual, set the Node ID in the gateway to an ID of your choice between 04
and 99. In the following example it is „42“.

If the gateway is either the only DP slave or the last DP slave in the Profibus line, the Bus terminator is
activated by setting both DIP switches to ON. In any other case set both DIP switches to OFF.

3. Simatic Manager (Step7 Software)

3.1 Creating a new project

Open Simatic-Manager (Step7 Software). For creating a new project call the assistant („File“ Æ
Assistant „New Project“).

Click on „Next“.

Select your CPU type. Another option is entering an individual CPU name. Click on “next”.

When selecting the blocks to be implemented chose OB1, OB82 and OB86. Select “AWL” (STL,
Statement List) as language for the chosen blocks.

Enter a project name of your choice (for example GK473) and click to „Finish“.

Now the project window showing the already implemented blocks will open.

You have to implement further blocks for the project. Select “paste“ -S7 block- and then the
appropriate option.

Install all the blocks shown above in successive order. In the following you will find further screenshots
for both data blocks and a chart of variables (optional but recommended for testing purposes).

After being defined in the SIMATIC Manager, loading of all data blocks into the S7 is imperative (select
blocks, then system of destination Æload)! Otherwise it will not work (neither there will be an error
message).
