<p>I'm developing a program running on a PC connected via RS485 to elements like PLCs and Inverters. I need to identify the type of element conected to the net...

Ex.

PC -----------------------------------
|01 |02 |03 |04 |05
PLC INV PLC PLC INV
</pre>
<p>Is posible to identify the type of the element conected on each address with a general function?

<p>Now I use the function 0x11 but not all the PLCs and Inverters have this function implemented.

Most that I deal with don't either.

I think that's why the spread sheet was invented, to provide an easy means of making tables.
