10.3.1 Acyclic data interchange

Introduction
Properties
Jetter AG
This chapter covers acyclic data interchange on the Jetter Ethernet system
bus.
Acyclic data interchange on the Jetter Ethernet system bus can be
characterized as follows:
Property
Architecture
Client
Server
Data
Access time
Configuration
Reach
Description
Client/server

Data interchange is initiated by the client.

The server gives a response to the request made
by the client.

Usage of unicast frames

Network access is made once.

JetSym:
Programming and debugging of application
programs

JetViewSoft:
Setting up a visualization application

Controllers:
Data interchange out of the application program
(NetCopy..., NetBit..., network register)

PC:
E.g. for database applications

Controllers, bus nodes and communication
modules:
E.g. variable or debugging server

PC:
Registers, inputs/outputs, STX variables,
application program

Controllers, bus nodes and communication
modules:
Registers, STX variables

It depends on the data transfer time and on the
server's processing time

Network registers:
Easy configuration in the application program

Else, both client and server are completely
configured by the operating system.

Using TCP/IP and UDP/IP frames allow for data
interchange exceeding the limits of one's own
subnet.
