Introduction

Due to their constantly increasing performance and vast availability of PC
applications for the manufacturing process, the Personal Computer is being
used more and more on the factory shop floor in addition to the programming
unit. This, however, poses the problem to you as the user how to combine the
variety of programs for handling of process data (e.g. data banks, statistical
evaluation) with your existing PLC systems. In order to make PLC data
available for the PC application you will need a working and cost effective data
link between PLC and PC.
This is where the software package PRODAVE S7 will offer the solution.
PRODAVE S7 offers tried and tested functions (tools) in a DLL (Dynamic Link
Library) or LIB (Library) which you can combine for each of your applications.
The combination of the tools is carried out in programming languages for
Windows 95/98/ME and Windows NT/2000.
Via these combined functions the process data traffic between PLC and PG/PC
is established by PRODAVE S7 using the MPI interface of the PLC. The data
now available can be translated into a format suitable for PCs and can be
processed by your own application or any standard application. This will enable
you to create a data link between PLC and PG/PC without having detailed
knowledge, and all your development activities can be concentrated on specific
processing of your data.
PRODAVE S7 enables you to not only evaluate and monitor but to influence
your process as well inasmuch that you can have several functions available to
you to enable you to write data to the PLC from the PG/PC.
As an introduction to PRODAVE S7 and to enable you to familiarise yourself
with it, we supply several demonstration programs as examples. These
functions are fully operational and are available in source code (see Para. 5.
Demonstration Programs).
PRODAVE S7 runs under Windows 95/98/NT/ME/2000 on PG 7xx and on Pcs
which are compatible to Industrial Standard in conjunction with MPI interfaces
(CP5411, CP5511, CP5611) or PC/MPI cables.
