Computer Applications at the Institute for Thermal Turbomachinery (Its): Integration of Personal Computer Data Acquisition Systems in a Local Area Network
At the Institute for Thermal Turbomachinery (ITS), computer systems are used in a variety of applications, such as data acquisition, numerical calculations, computer graphics, word processing and administration. The broad range of different tasks requires system architectures individually matched to each application. Therefore, standard systems could not be used in most cases and a heterogeneous data processing environment was developing quickly where the compatibility of the systems was quite limited.
In order to maintain an optimum availability and transparency of the data processing services to all users in this University Laboratory environment, especially to students, great efforts have been made to interconnect the systems by means of a local area network (LAN) and to provide user interfaces that are as similar as possible.
The installation of several Personal Computers that are used in the educational program ‘Energielabor’ (Energy Lab) has triggered conceptional changes in the structure of the data acquisition subsystems, leading to a considerable increase in the number of PC-based systems during the last three years. Consequently, it was necessary to integrate the PC’s into the LAN segment. By that, the peripherals of the VAX and PDP minicomputers available in our network (laser printer, plotters, etc.) can be shared with the PC systems and the mass storage devices (disks, magtapes) are available for backup. To facilitate the administration of the PC systems, the VAX acts as a network file server where the latest copies of the system software and utilities are stored.
