Dear Experts!

I have a requirement to configure HART enabled flow meters so as to read Flow rate and total volume. In general for most of areas in our Plant we have DCS system installed-for which cards are by-default HART compatible. however, for few areas we have installed PLC which are non-HART. 

So, for these few areas, I am considering of installing a new PLC & few cards, which would be compatible with HART. 

Please suggest based on your experience some compatible PLC models, which can provide an AI Module which is HART compatible. 

Thanks in Advance.

Hi rajesharihant,

Siemens analog modules are very flexible in HART compatibility. Recently i come across with HART level transmitter connection to an ordinary analog input module. And it was successful.

Connected Info: TX+ connect to + 24DC, TX- connect to +AI and –AI connect to -24VDC

Am also attaching specific Siemens HART modules info with this message.
