Wonderware Siemens 
3964R I/O Server 

 

Introduction 

The Wonderware

 

Siemens 3964R I/O Server (referred to as the server through the 

remainder of this user’s guide) is a Microsoft

 Windows

 application program that acts 

as a communication protocol server.  It allows other Windows application programs 
access to data within the SIMATIC

 S5 and S7 family of PLCs (also referred to as 

devices).  The server allows the PC to access a Siemens PLC through a CPU or CP 
which supports the 3964R protocol with RK512.  While the server is primarily intended 
for use with Wonderware InTouch

 (version 3.01 or later), it may be used by any 

Microsoft Windows program capable of acting as a DDE, FastDDE, or SuiteLink

 

client. 

Communication Protocols 

Dynamic Data Exchange (DDE) is a communication protocol developed by Microsoft 
to allow applications in the Windows environment to send/receive data and instructions 
to/from each other.  It implements a client-server relationship between two concurrently 
running applications.  The server application provides the data and accepts requests 
from any other application interested in its data.  Requesting applications are called 
clients.  Some applications such as InTouch and Microsoft Excel can simultaneously be 
both a client and a server. 

FastDDE provides a means of packing many proprietary Wonderware DDE messages 
into a single Microsoft DDE message.  This packing improves efficiency and 
performance by reducing the total number of DDE transactions required between a 
client and a server.  Although Wonderware's FastDDE has extended the usefulness of 
DDE for our industry, this extension is being pushed to its performance constraints in 
distributed environments. 

NetDDE

 extends the standard Windows DDE functionality to include communication 

over local area networks and through serial ports.  Network extensions are available to 
allow DDE links between applications running on different computers connected via 
networks or modems.  For example, NetDDE supports DDE between applications 
running on IBM

 compatible computers connected via LAN or modem and DDE-aware 

applications running on non-PC based platforms under operating environments such as 
VMS

 and UNIX
