Hello,
I have been getting more and more requests for Real Time Clock (RTC) sensitive automation from my clients.
I know that there is a Modbus RTU/TCP time module available from ProSoft/Appian.
My clients are not going to buy this module for each and every site, so I thought maybe I could try something using Python and an SBC.
I know how to set up a Raspberry pi and sync it's clock to NTP or GPS. I even have a "GPS Hat" with RTC battery. Arduino would probably be more stable, and I could figure that out too.
I was thinking, geez, Maybe I could run a modbus server (slave hopefully, so a PLC can poll it) and maybe have registers for DD:MM:YY:HH:MM:SS.
Anyone have experience trying this crazy solution?
Thanks!
