Revision history

Rev. 101 31.10.2025
Rev.  270 05.11.2024 : develop reliable Modbus communication to smart meters

Just read a set of input registers of an eastron smart meter, SDM630 e.g.

NOT ready!!! playground to get rid of Stepane's overhead.

Library usage

Build the program

cross-compile by:

make PROGRAM=meterModbusTest TARGET=meterPi clean all 

program by:

make PROGRAM=meterModbusTest TARGET=meterPi FTPuser=sweet:0123 progapp 

or due to some bugs in make use winscp and IP directly by:

winscp.com /script=progTransWin /parameter sweet:0123  meterPi bin meterModbusTest
