MEgA - Merici Energeticke Aparaty
The communication unit MEg202.5 in its basic configuration provides remote transmission of states or changes of binary inputs and commands by GSM / GPRS, UMTS / HSPA and LTE networks of mobile operators. The measured values are transferred through the serial communication line RS485 from connected measuring devices.
The unit installed in the station technology can be connected through two RS485 serial interfaces and it implements the standardized communication protocol according to EN 60870-5-104:2006 and allows integration of connected devices into the SCADA system, either directly or through concentrators. The units has a processor that optimizes and controls data transmission, communicates with connected devices through technological network, allows pre-processing of data read from measuring devices, supervises connected devices and automatically transmits data to a host system in case of an event.
The MEg202.5 unit can be used also in the function of a communication converter GPRS / UMTS / HSPA / LTE on RS485 bus when the data sent through the mobile operator network are re-sent in transparent mode to the programmed RS485 channel and conversely, the data from RS485 are sent back.
