Holding & Input registers which type is Read only?

Postby viokast/yahoo_gr » Thu Feb 09, 2017 12:11 pm

Hello all,

In the text (Aggregate Documentation 5.31.15, page=185) :
the Holding registers described as Read-Only registers, and
the Input Registers described as Read/Write registers.

In the Modbus protocol (see modbus.org specification)
this is quite the opposite :
Holding registers : Read/Write,
Input registers : Read only

My question is if the software treats the modbus registers in the way the manual describes,
or the way the modbus protocol defines them (so it is only a mistyping).

Please clarify.

Hi Nikolas,

Thank you for this notice.

My question is if the software treats the modbus registers in the way the manual describes,
or the way the modbus protocol defines them (so it is only a mistyping).

I'm sorry for this mistypes. Of course second variant is correct.
We fix our documentation soon.
