6 Operation

6.1 Overview

iec104sld is a server application that runs on a Linux server and acts as an IEC 60870-5-104 Slave station simulator maintaining an IEC 104 session over TCP/IP to remote IEC 104 controlling station (master).

iec104sld is managed remotely either from a Windows PC using ls104slgui.exe applicationor from Linux shell using iec104s command line utility.

Additionally the product is shipped with the Windows version of iec104sld (iec104sld.exe) which starts by the Windows GUI before connecting to it (to 127.0.0.1).

The application supports simulating command points and data points which can be added, edited or deleted using the Windows UI or the command line interface.



6.2 Windows GUI Porgram

Windows GUI control program is used to manage iec104sld IEC104 Slave Simulator. Mainprogram's views and control areas are shown below:

(1) IEC104 Link and Application Layer Management group of controls. This area is used to change and update IEC104 configuration, start and stop IEC104 data link.

(2) IEC104 Protocol Statistics view. This view shows IEC104 data link and application layer statistic counters.

(3) Outstation data points. This view displays the configured information objects.

(4) Outstation data points control area, Here it is possible to edit, add or remove properties of configured data points.

(5) Outstation command points. This view displays the configured information objects related to the commands that the controlled station is able to process.

(6) Outstation command points control area, Here it is possible to edit, add or remove properties of configured command points.

(7) System log. This view shows the events logged by iec104sld. Beside viewing the log, it is also possible to pause, resume and export the log.



6.2.1 Connecting to iec104sld

Click “CONNECT” button.You will see dialog box “Connect to LabScada IEC104 Slave”.

Enter the IP address of your Linux server on which the iec104sld is running and specify the TCP port number configured for GUI access in the iec104sld configuration (by default port 3335)

Click “Connect”. Connection to iec104sld should get established. You can then manage the IEC104 parameters and perform other control tasks.

The TCP port on which iec104sld is listening is configured in the iec104sld configuration file in the option netui_port (On Linux stored by default at /etc/iec104sld/iec104sld.cfg):

To disconnect from iec104sld you can click “DISCONNECT” button.
