I'm trying to communicate with a RTU current and voltage analizer for Photovoltaic Plants.
I have been able to communicate with it with Modbus Poll in Windows 10 but it has been imposible with mbpoll in ubuntu server 18.04.5.
These are the registers I'm trying to read.
These are my modbus poll parameters.
The ttyoS0 from my Ubuntu Server PC is configured:
And I use a cable with this configuration:
BPC (DB9) - RTU
A+ 2 A+
B- 1 B-
GND 5 GND
And this is my mbpoll command.
Apparently I'm sending the send bytes as in Modbus Poll with windows.
I have also tried with 2 stop bits but without any success,
