All necessary jobs for a trouble free operation, such as the
configuration of each single channel, editing of telegrams, transmission and receipt of telegrams, archiving etc. can be
called up out of one mainframe. Each required function can be called or activated without
problems via easy comprehensible buttons. While recording is running trouble free in the background, telegrams can be
edited, sequences created, filters that are necessary for recording or action filters that are necessary for the
simulation can be set in the meantime.
-
Telegrams can be sent single, cyclic or multiple. Furthermore
several telegrams out of different TDB buffers can be linked to a sequence. Faulty
telegrams can be edited and sent, too ( K1... K8 ).
-
You can receive and transmit on four channels ( optionally
8 channels ) simultaneously and set each channel for another protocol. The change between the individual protocols can be
handled quickly and without problems. The settings of the single channels with all for the operation necessary settings of
paramount and protocol- specific parameters is done clearly and comfortably via input- dialogue- or selection fields.

Recording of the transmission data is not limited to a small time window
but can last several hours or even days. All recorded data are stored chronologically for later analysis in an archive file
having a size of up to 32 Megabytes and each entry in the archive file includes the actual time. During recording, the
transmission is permanently supervised on transmission errors. If an error occurs, an error message ( e.g. checksum error )
is stored together with the transmission data in the archive file and further detailled information to the error in the
PRO-File. All send- and receive data are stored in the archive in binary code. When opening
the ARC file this recorded data are converted to an easily read procedure specific plain text
and displayed on screen. In order to optimize the output you can select between 5 different display formats
( FMT file )
-
As one is interested only in some specific parts of the records in
most cases, it is possible to activate data format specific filters and triggers for the recording
( VFL file ) or the analysis of the recorded data ( NFL file )
in order to achieve a carefully directed data pre-selection, which results in a reduction of the data.
-
Of course, the LIAN 98 software can be used besides the
protocol supervision also for the simulation of subsystems like outstations and master stations, process interfaces
( telecontrol head or telecontrol nodes ), process computers etc. The software can work thereby alternatively as master-
or substation. Messages or link records can be transmitted individually or as a non-channel-specific sequence. For each
transmission protocol up to 500 send buffers are available that can be allocated freely by the user
( SIM file ). You will find further details to the simulation in the description
of the individual protocols.
-
With the dial-up function ( AWD ) it
is possible to test stations ( master or substation ) via phone line. The LIAN 98 software can make a connection via modem
and phone line to a remote station and transmit data to or receive data from this station. In this way the necessary tests
can be done comfortably out of the office via the phone line. The login takes place with a password.
