Pc Communications Settings

When SYPT goes online the PC communicates with the nodes in the project using the protocol appropriate for the network to which the PC is shown connected in the Hardware Architecture view of the Configuration Editor. The network to which the PC is connected and settings such as the COM port and baud rate can be set by selecting the PC and editing its properties.

To view or change PC Communications Settings

Do one of the following:

Double-click the PC.
Select the PC, right-click and choose Properties from the popup menu.
Select the PC and on the Edit menu, choose Properties.
On the Run menu, choose PC Communications Settings.

The PC Communications Settings dialog is displayed.

This dialog allows the network to which the PC is connected to be altered. If a CT-RTU network is selected, the dialog also allows a node ID range to be set. By default when SYPT goes online and looks for nodes it will search for nodes 1 to 255 on a CT-RTU network. This can take some time since CT-RTU is a serial protocol and is relatively slow. To speed up the process of going online with the CT-RTU protocol, the range of node IDs for which to search can be restricted in this dialog. If the lower and upper node numbers are set as shown in the above picture, SYPT will only attempt to look for node 1 on CT-RTU when going online.

If the Settings button is pressed, the Communication Settings button is displayed.

This dialog allows more detailed communications settings to be specified such as the baud rate and COM port or CTNet card to be used. Pressing the Help button on this dialog accesses the PC Communications help file.

Rearranging Networks

You can change the order in which networks appear in the Hardware Architecture view.

To change the network order

From the View menu, choose Change Network Order.

The Change Networks Order dialog is displayed.

To change the position of a network in the network order, select the network in the list and then press the Move Up or Move Down button to move the position of the network in the list. When the order of networks has been changed, press OK and the order in which networks are displayed in the Hardware Architecture view will be changed to match.

Splitting Network Rails

Within the Hardware Architecture view it is possible to split network rails so that rails containing many nodes can be made to appear on two or more rows. Splitting network rails can be done in two ways:-

1. Split the networks manually - the user chooses the nodes at which rails are to be split.

2. Split the networks automatically - SYPT splits the rails to make as many nodes viewable as possible within the width of the screen.

To split network rails manually

Select a node or annotation where you want to split the rail and do one of the following:

From the Edit menu, choose Split Rails.
Right click and from the popup menu, choose Split Rails.
On the View toolbar, press

The selected node or annotations and all following nodes in the same row are moved down to create a new row.

For example, the following shows the Hardware Architecture before splitting a rail at node 3.

Then after selecting node 3 and splitting as described above:

To split network rails automatically

From the View menu, choose Auto Split Rails.
On the View toolbar, press
