The goal of the thesis was to build a measurement sistem that includes an energy
meter ISKRA MC740 with a serial output and a programmable logic controller
(PLC) Siemens SIMATIC S7-1200. In order to connect the energy meter and
the PLC, the PLC had to be expanded with a communication modul SIEMENS
CM1241, which enables data transfer via serial RS485 communication protocol.
A great emphasis in thesis is also on the measurement data conversion from the
energy meter to appropriate data type, that is suitabe for the PLC enviroment.
Finnaly a user interface is designed to display basic data on the touch screen.
