iPLON Magic Box
IEC-60870
OVERVIEW
iPLON – “Magic Box”
iPLON Magic Box Standard
 Interface between the PV plant (rooftop or
Power Plant) and the Energy Utility Company
 Based on the technical specifications of the
German requirements of BDEW.
 Control of the PV plant is achieved by the
active control of the inverters used in the
plant.
 Suitable for new plants as well as integrated
in existing Power plants.
 iGATE Datalogger (with IEC 60870-5-101/104
protocols)
 Connectivity to cloud based system and SLDCs
with DSL, GPRS, VPN, RT, PLCC
 I/O system
 Supports Modbus, TCP/IP, LON

IEC 60870 origin
• International Electrotechnical Commission 60870
Standards (IEC 60870)
• 60870 standards are developed by IEC Technical
Committee 57 (Working Group 03)
– Define systems used for telecontrol (supervisory control
and data acquisition) in electrical engineering and power
system automation
– For controlling electric power transmission grids and other
geographically widespread control systems.
– use of standardized protocols, equipment from many
different suppliers can be made to interoperate.
