SCADA system applications have been become an
indispensable necessity in today’s automation industry.
SCADA system performs different tasks with PLCs
communication systems, and the well-known WinCC Scada
software is produced by Siemens Company. In this study,
communication of the S7-200 PLCs with the CP5611 PCI
card, and using bus type connection topology for speed and
efficiency, has been preferred. Because other network
topologies are uneconomical and technically incompatible
with PLCs, in this study only bus topology has been used.
Control of PLC training sets and an educational industrial
training lab is achieved via a SCADA system. In addition,
under supervision of the teacher, a computer can be
centrally monitored ensuring the ability to control and
monitor applications simultaneously.
