SOFTWARE IN THE SERVER
Server PCs can be used e.g. to connect several con-
trol units to a ChromLAN loop. Servers can also
reduce the load on the control computer if many
chromatographs are connected.
At least one coupling module must be installed to con-
vert the PC into a server, and additional software is
required. This is supplied on diskettes or already in-
stalled on the hard disk:
Server software
Interface driver
Server software
The server software is supplied on a diskette which
contains a program to install this diskette on the server.
The server software communicates with the chromato-
graphs, control system and control unit via the inter-
faces of the coupling modules. The software collects
data from the chromatographs and passes them on to
the control unit or control system.
The server software must be assigned parameters.
These settings are then stored in parameter files.
Interface drivers for coupling modules
At least one coupling module must be installed in the
server. The module has two serial interfaces. Each mo-
dule has a diskette with interface drivers:
Coupling to a control unit or
the
protocol. This driver is called
D3964R
Coupling to a control system with the
protocol. This driver is called
The coupling module and diskette belong together and
only function if they have the same serial number!
SOFTWARE IN THE
CONTROL SYSTEM
The chromatograph information is stored in data struc-
tures in the control system. Data address lists must be
declared when configuring so that the control system
can assign these data.
