I have been trying to figure out how to write a small bit of code to simply poll the 4 variables via HART. Right now I'm trying with Python on my PC (using a RS232 to HART adapter and an E+H FMI51 as a guinea pig), but so far no luck. Any good examples out there without going straight to the protocol documentation? I found an existing software package called MBLogic, but it doesn't seem to work, as I can't get any HART devices to response, even with errors. I was hoping that PACTware had an API or something I could use. End goal (for now) is simply to be able to log from a HART device. End goal (future) is to be able to use an RS232 to HART adapter on a MicroLogix or other PLC to do HART comms that way. Thanks for any help.
