I have create program Modbus22 for Rtu and Ansi protocols for basic communication with some solar invereters and similar devices. Program Modbus22 Rtu is suitable for reading data with commands 03 and 04, Modbus Ansi is oriented on my inverter PS3KVA and now for most reading commands like QPIGS . I use this programm for my actual devices SDM120M and SUN100G (Rtu) and PS3KVA (Ansi). Program is created for Windows 10 by Delphi XE Starter version 2015 .
I am reconstruct the Modbus Ansi protocol for my inverter PS3KV A at first for the basic command for data readig - QPIGS .
I attach some printscreen of this my programm Modbus22 ad how I have reconstruct the PI30 protocol for QPIGS command i text file.
