SOFTWARE IN THE
CHROMATOGRAPH
The chromatograph can carry out analyses auto-
matically without a control unit being connected.
To achieve this, you must
Load the control software and interface driver
Configure the system
Load the methods
Set the analysis parameters.
BIOS
The computer in the chromatograph is called
PCPU-2
. It
has two
EPROM
s which contain the BIOS.
Control software, interface drivers
There are flash
EPROM
s on the
PCPU-2
for the control
software and the interface drivers. Flash
EPROM
s can
be electrically deleted and programmed directly in the
chromatograph.
The control software and the interface drivers must be
loaded from the control computer into the chromato-
graph via a serial interface. Software updates can be
carried out very simply in this manner.
SOFTWARE IN THE CONTROL UNIT
Every
IBM
-compatible personal computer has the
BIOS
in built-in
EPROM
s. The
MS-DOS
operating
system must be installed on the hard disk.
Further software which is supplied on several diskettes or
already installed on the hard disk is required to convert the
personal computer into a chromatograph control unit:
Installation program
Control software and interface drivers
Configuration
Screen operation with
ChromLAN
If applicable, supplementary software such as
GCLAN
,
GCARCHIV
If applicable, further special interface drivers
If applicable, server coupling
Installation program
The first diskette contains the installation program. This is
used:
To install the software on the control computer
To load the control software with interface drivers
into the chromatograph. You can select either labor-
atory or process versions, and the use of the inter-
faces.
Control software, interface drivers
The control software for the chromatograph is stored on the
control computer in order to be able to subsequently load it
into the chromatograph.
Configuration
The configuration is used to set the elementary par-
ameters for the chromatograph. These are the par-
ameters which are not often changed, e.g. chromato-
graph type, module designation or valve names.
Screen operations
Operation does not only mean the generation of colour-
ful pictures. Programs are also required which are re-
sponsible for the invisible procedures in the control
computer:
Network software
ChromLAN
Network initialization
INITCHRO
Multitasking
PGCRES
Stores information onto the hard disk in the back-
ground. This information is obtained from the chro-
matographs via
ChromLAN
, e.g. analytical results,
chromatograms, status.
Printer spooler
LPRINT
or
CPRINT
Passes information on to the printer in the back-
ground. This information is obtained from the chro-
matographs via ChromLAN, e.g. analytical results
or status information.
Supplementary software
The software packages
GCLAN
and
GCARCHIV
are
supplied on separate diskettes. The installation program
also copies these programs onto the control computer.
Server link
An additional interface driver is required in Chrom-
LAN networks with servers to link the control unit to
the server. The driver is called
TELI
and uses the
D3964R
protocol on
ChromLAN
.
