Are any of the Modicon M340 analog input modules compatible with HART signals?
No, the Modicon M340 does not support HART signals.
However, there is a Telefast block which can be used to filter out the digital component of the HART signal allowing only the analog component
to be seen by the analog input. The part number of the block is ABE7CPA31E.
The M580 does have a HART solution using the BMX Analog IO. The BMEAHI0812 HART Analog Input and BMEAHO0412 Hart Analog Output.
