Features:

Interfaces and Remote Control
iseg HV Power Supplies and systems are equipped with
various analogue and digital interfaces. This is to allow the
use in many different applications. Depending on the
complexity the range of products is starting with simple
analogue interfaces, with control and monitor voltages for
output voltage and output current further to the simple
implementation of serial interfaces like RS 232, field busses
and laboratory busses like CAN and IEEE 488 finally up to
more complex interfaces of standardised systems like VME
and CAMAC..

Programming examples
Programming examples and application software together
with the source code is available for the control of iseg HV
PS via various interfaces. The programming examples are
intended for easy use and they should allow to understand
the operation in principle. According to the steadily growing
demands for applications (operating systems, development
environments) these examples have to be improved conti-
nuously. New updates are available on the iseg web site
www.iseg-hv.com under support.

CAN BUS library
The following programmes are using a standard library for
the communication of the hardware. This library offers either
the interface to the hardware drivers and it gives access to
specific module commands. The library is – at this time –
limited to the use with hardware of the PEAK System Tech-
nik GmbH (www.peak-system.com).

Application programmes
For the use in simple remote controlled systems and units
and in order to establish easy running applications iseg
offers the “isegHVM” software. This software which is
running under Windows controls the communication
between a PC and HV PS units via CAN.
The essential steps in order to set up and test the equip-
ment can be done (configuration, test and communication,
setting and reading of single parameters with different
units). The “isegHVM” is an indispensable tool for tests and
for setting up operation.

OPC Server
iseg is offering an OPC server for bigger systems running
via CAN interface (OPC = OLE for Process Control). Fast
and safe data communication can be set up for this
Windows based systems using the basic technologies of
Windows (DCOM).The OPC server describes the ins-
trument parameter, setting, control and monitor as so called
“items”. Using any application software (OPC clients) the
access methods which have been defined in the OPC
protocol allow to have access to these values. Especially
the advantages of the client/server technology are impor-
tant, the transparent use of networks, the use of several
and different clients and the placing of access rights.
A configuration tool, which supports the configuration of
the hardware (CAN interface in the PC and iseg HV PS) is
part of the OPC server.

OPC Client
The iseg application software “ScriptLoader” is such
an OPC client. Working together with the OPC server it
generates configuration and protocol runs. The software is
controlled by an ASCII-script and allows a time-controlled
“setting“ and “reading“ with help of time stamps.
The output protocol in ASCII format can be post-processed
in standard visualisation software.
