I have been asked about the CSI capability from a client around measuring HART FSK, this is not something I am familiar with or had any experience beyond standard 4-20mA sensing and use of HART interfaces for configuring sensors.
A brief look around the website I couldnt find any specific information but hoping I might get some clarification
The question related to
Hart FSK (Frequency Shift Keying) Communication Protocol as per https://www.fieldcommgroup.org/technologies/hart
If they can't read it on the current I/O mA input then other option maybe a Hart to RS232 modem, but I was hoping to avoid the extra cost.
Potentailly the hart to rs232 might be the solution but open to any suggestions
Thanks

The datalogger hardware does not have a way to directly do the FSK modulation.
Generally, customers use a HART to Modbus converter, when they need to HART data. The main data value of the sensor can be read as a normal 4-20mA signal.
thanks for the confirmation
