1Introduction
Thank you for Buying ATOP’s Protocol Gateway.
The product is bundled with the following three user manuals:
1) Hardware specific installation user manual, not covered in this document. It covers ATOP’s hardware
installation procedure, wiring, power connection etc.
2) Getting started with ATOP’s Protocol Gateway user manual – configuration tool introduction, web
configuration, software architecture introduction–not covered in this document. This manual covers the
introduction, installation, network set-up maintenance and using of the configuration tool software,
including the procedure to be followed for uploading new configurations to ATOP’s device.
3) Protocol specific user manual (This Manual). One protocol-specific manual will be provided for each
protocol installed on the device. This manual covers:
a. Basic device network configuration
b. Step-by-step protocol set-up for in eNode designer
c. Description of the protocol-specific software features, the device profile and the implementation
table of supported functionalities.
This manual is for IEC-60870-5-101 and IEC-60870-5-104 client server and describes how to use the IEC-60870-
5-101/104 eNode Designer Module to configure ATOP’s IEC 60870-5-101/103 ADH Application within the eNode
Designer configuration tool.

2General Description
2.1 Adding the IEC 60870-5-101/104 ADH Application
An IEC 60870-5-101/104 ADH application can be set up as a Client or a Server. This choice will be presented when
adding the application. Please note that ATOP Protocol gateways supports one Server application per protocol
per device.
Right click the intended port for the IEC 60870-5-101/104 ADH application.
Left click Add ADH Application.
Left click IEC 60870-5-101 or IEC 60870-5-104. eNode Designer will automatically choose between IEC
60870-5-101 or IEC 60870-5-104 depending on what type of port the application is being added to.
This dialogue box will appear, asking whether the new application is to be configured as a Client or a Server.
Select either Client or Server from the drop down menu.
Left click OK to add the application.
There are differences when configuring the new ADH application depending on whether it is an IEC 60870-5-101 or
104 and whether or not it is configured as a Server or a Client. See the following links for specific configuration
information:

3.1 IEC 60870-5-101 Client configuration
The following view is shown after an IEC 60870-5-101 Client Application is added. It is also accessible by left
clicking the ADH Application in the Project Tree.
The Settings tab, this is shown when clicking on an IEC 60870-5-101 ADH application in the Project Tree.
The Remote IED tab, this shows the Address, Data and Commands settings for the remotely connected
IED(s). The settings in this tab are specific to the individual IED. For more information see: IEC 60870-5-
101 Client, Remote IED Tab Layout and Address Settings. This tab can also be accessed by clicking the
specific IED within the Project Tree.
The add IED option. This creates a new remote IED, which will be visible in the Project Tree and brings up a
new IED settings tab for individual IED configuration.

3.1.3 IEC 60870-5-101 Remote IED Data Point List
This section shows the data points for the connected IED. It allows addition, modification and deletion of data
points as well as list sorting.
Left click Add to add one or more new data points. For more information on the Add Data Point tool see:
Adding Data Points. Initially only this button will be available for the user. Once a data point has been
created and/or selected by left clicking (data point will be highlighted) the other command buttons become
usable.
Click the +1 button–This will add a new data point with details copied from the selected data point, with
an automatically increased Address. eNode Designer will make sure that a new unique tag name is
generated for the point.
While one or more data points are selected, clicking Delete will remove it/them immediately unless they
are mapped to a server, in which case, a dialogue box will ask for confirmation on the deletion of the
point(s).
While one or more data points are selected, clicking Modify Selected Points will bring up the a dialogue
box similar to the Add Data Points Dialogue box, however this box shows the original data point
configuration as well as the new configuration for comparison.
Move Up and Move Down can be to shift selected data points within the list.

When adding data points, this dialogue box will be shown.
Data points will appear in this section as a preview before they are added to the IED.
Data point information is entered here. Tag, Start IOA and Count are entered manually while Data type has
drop down menus for selection. For specific information on these parameters, see Data Point Parameters.
This section can be utilised to make adding multiple similar data points easier. The values “[X]”, “[Y]” or “[Z]”
can be entered in Tag as an auto increment counter. For more information on how to use the auto-
increment feature see: Using Auto-Increment.
Once the required data points are shown in the preview section, click OK to add them to the IED.
