My client wants to have all transmitters with HART protocol. But some special transmitters like weighing transmitter from Sartorius (there is no other option) do not have HART. So the solution is to buy transmitter with 4-20 mA and Modbus on RS-485. Then buy third party’s modus+4-20 mA to HART converter (suitable for transmitter).
Now this converter does not have Device description (DD) file. Converter vendor asked to use Generic DD file from DCS vendor.
Now my quotation is?
1) Since the transmitter is not as per HART standard, is this system useful to client?
2) What type of data available if I use generic DD file for transmitter (any other transmitters).
3) What kind of data required from transmitter (HART) to connect with asset management system.
Is there any technical reason so I can convince client not to have weighing HART transmitter .
Thanks in advance.
