Bluelotus Posted April 15, 2011 Report Share Posted April 15, 2011 Hi, I would like to know and understand the necessity of using the Power Up Bit SB 2 in the Ladder Program. I would appreciate it if someone could provide small examples where to use a power up bit and where it is not required. Thank you very much and have a great day.

Jas Posted April 15, 2011 Report Share Posted April 15, 2011 System Bit 2 is unique in that it is only high for a single scan at power-up. Generally it is utilized for configuration parameters of our communications function blocks (Serial, Ethernet, CAN), PID, Loadcell, PTO, etc. 1 Link to comment Share on other sites More sharing options...
