Starting the parameter assignment dialogs for networks and network nodes

If you double-click on a network or network node icon or select the

Object Properties

in the context menu (right-hand mouse button), the

Properties

dialog opens to allow you to

set parameters. Here, you can connect modules with networking capability with the networks

and adapt the properties of the relevant object to your requirements. All parameters have

default settings that simplify parameter assignment.

First the network attachments are made.

1.6.1 Generating network attachments

To network a project, the communication-compliant modules (for example CPU or TIM) must

be connected to suitable networks. The modules in the station icons in the project window of

the network configuration include interface and network node icons displayed in different

colors according to the network type.

Figure 1-17 Icon of a master TIM station in the project window of the network configuration

containing a TIM module and three network nodes

The station icon shows a master to containing a communication-compliant TIM 44D module.

This module has three network nodes, visible as small squares in the module icon. If these

network nodes are not connected to a network as in the example, the relevant network node

is not networked.

You connect network nodes with the networks using the mouse by dragging the network

node icons to the line of the required network.
