All process dependent data are available in a data base system of the control center computer. LIAN 98 offers the possibility to import these process data and use it for the IEC 101 / IEC 104 simulation. Therefore it is necessary that the process computer can export station for station specific information out of its data base into a text file ( e.g. comma separated values ).

The following data must be available per data points :

. Information object address ( IOA )
. Typ identification ( TypeID )
. State of information ( ON/ OFF ) for single and double point information
. State of command ( ON/ OFF ) for single and double point commands
. for the commands additional the information "select or execute" ( S/ E ) and the pulse duration time
. the description of the data point as plain text

The file should also include the ASDU address ( station address ) and the station name.

When all above criteria fulfilled and the structure of the file to be imported into LIAN 98 is known, the data can be imported. If the structure of the import data is still unknown we are pleased to implement the necessary import moldule free of charge for you.

The process data description is organized line by line and can accommodate up to 5800 data points, whereby each data point is one line.
