The LIAN 98 software, running on the operating systems Windows®
( 98, 2000, XP, Vista and Windows 7 ) from Microsoft®, can be used for various tasks in the
field of process control systems and telecontrol systems :
. for the simulation of control center systems and remote control systems ( master- / slave simulation ),
. for monitoring, supervision and analysis of data transmission lines,
. because of 12 channels to examine the dynamic process behavior ( stress test )
. and as protocol router from IEC 101 to IEC 104.
The software has been developed to analyze data transmission independent from special measuring instruments for pulse-code-modulated
serial and network protocols. Also to simulate particular components and systems such as master stations, substations, process interfaces
like telecontrol-heads and nodes, in point-to-point or multi-point trafic to recognize transmission errors or erroneous data.
The software is equally suitable for developers of telecontrol or power control systems when testing, commissioning and maintenance
of telecontrol installations and for operators of existing telecontrol systems for supervision, error analysis and in order to carry
out data tests.
Editing of send telegrams as well as the display of sent and received data is done on a logical level. All telegrams are realized
and for each telegram clearly laid out masks are available to set the necessary values. The plaintext display mode
of the transmit and receive data facilitates to recognized easily particular values. This means, the laborious and time-consuming
analysis of bits or the conversion of hexadecimal values has been dropped completely for service teams.
A great advantage for system tests is the use of imported process data. This causes for testing a significant reduction in
expenditure of time, because particular process messages must not be edited. The messages are automatically generated by
the LIAN 98 software on the basis of the data point list. At the moment import of process data lists is only available for the
protocols IEC 60870-5-101 and IEC 60870-5-104.
LIAN 98 can be used as protocol router between the protocols IEC 101 and IEC 104. This function is especially suitable for small
process control systems ( building automation, emergency systems, ... ) with only a few substations. When using all twelve channels,
10 ( point-to-point ) substations can be routed to 2 network capable IEC 104 control center computers.
