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-DP-
capable 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.
