Purpose of floating ground in 24VDC power supply input. In the PLC Demo board provision for two wire and three wire 24VDC is there 24V+ and Gnd is understood but why have you provided third connection and termed it as floating ground.
This "floating ground" should read "EARTH" as this is for an earth ground connection. This article will be updated to correct this.
Could you please provide some more information, as to the PLC demo system you are referring to?
Thanks for your reply. I am referring to Analog Dialogue 43-04, April (2009) by Colm Slattery , Derrick Hartman and Li Ke.
