Hello, i have a strange behavior with an janz tec emPC imx6 and i use the last codesys control 3.5.11.20 for it ,
i want some data exchange with an Schneider M251.
The behavior is :
read 1 holding reg - OK,
read n holding reg not working, all values are set zero...,
with an modbus tcp scaner modscan32 i can read well from M251,
In M251 i use builtin modbus server..
any suggestions??? please...
