Pre-Scaler Issue about open-plc-utils

[n1000]

Have you tried the tools 'psout' and 'psin'? They allow you to read and write prescalers in a PIB file.

Also, what PLC chipset are you working with?

Hi, thank you for your reply.
With Psout and Psin i can only read them.
I've all kind of QCA, for example we have QCA7000, QCA7420 and QCA7500 chipsets.
Please help me! :(

I don't think these tools will work for the QCA7500, but for the other chipsets the general procedure should be:

psout file.pib > prescalers.txt
edit prescalers.txt
psin file.pib < prescalers.txt

Does this procedure not work?

According to your screenshot your host platform seems to be ARM. Could you please retry with an x86 PC?

I've tried by Pc with Linux on board. What do you mean, this?

Okay, i was confused by the DietPi.

Please also take a look at this conversation.

How i can see in that post, it's impossible to modofiy amplitude of PLC channells.
I can't see any solutions for this problem.
