Hi all,
my problem is that the modbus does not work properly with the SP15, while it works well with the SP11.
With the SP11 I can read all the parameters, while with the SP15 I don't. To better explain the situation,
I have attached two images, where it can be seen that with the SP11 I can read all the modbus parameters,
while with the SP15 some yes and others not.
What can I do to solve the problem?
Thanks.

Did you try to sniff the communication with Wireshark to better understand if there's some error into a slave channel?
