Network nodes are the controller, the communication modules and the bus
nodes.
For details on characteristic features of publish/subscribe, please turn to
chapter Hardware Manager (see page 254).
Publish/subscribe is configured in the JetSym Hardware Manager.
Publish/subscribe is executed by the operating system of the respective
network node:
 Publishers and subscribers are configured by means of configuration files
in the file system of the network nodes.

The configuration file for the publisher is
/SysConfig/JetSync/Publisher.pub .
 The configuration file for the subscriber is
/SysConfig/JetSync/Subscriber.sub .

Automatic restart of the publishers and subscribers takes place in a
controller at each restart of the application program.
 In the other network nodes, automatic restart of the publishers and
subscribers takes place during the booting phase.
 For applying publishers and subscribers in a controller, an application
program must be executed with at least one task running.
For transferring the configuration, the Hardware-Manager takes the following
steps:
Step Action
1 Stop all publishers and subscribers.
2
