viscoelastic Posted February 1, 2017 Report Share Posted February 1, 2017 When PLC starts I need it to clear all previous settings/bit values. I tried |----(SB2)---(SB24)---- all that did was put it in a constant reboot situation. Thank you in advance for helping me with these greenhorn questions.

MVP 2021 Joe Tauser Posted February 1, 2017 MVP 2021 Report Share Posted February 1, 2017 You've learned that SB24 blows everything out and causes the PLC to reboot. Stay away from it. If you look at the memory table at the bottom of the screen you'll notice a column with a little electric plug looking thing. No, it's not a bell. This is for setting a power-up value. Enter "0" into the MIs and "Reset" into the MBs you want to clear. Joe T. Quote Link to comment Share on other sites More sharing options...
viscoelastic Posted February 2, 2017 Author Report Share Posted February 2, 2017 Do you mean in SB2? I can set it to "set" or "reset" Thank you Quote Link to comment Share on other sites More sharing options...
viscoelastic Posted February 2, 2017 Author Report Share Posted February 2, 2017 Do I have to set each MI and MB or is there a way to do it globally? Thanks Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted February 2, 2017 MVP 2021 Report Share Posted February 2, 2017 The powerup value is an individual setting. You can do larger chunks using SB2 and Fill blocks. How many things do you need to reset? If you post your code with more specific details I can put some resetting code in for you . Joe T.

viscoelastic Posted February 2, 2017 Author Report Share Posted February 2, 2017 It's not that many that I have to go through. I was asking for future use. I Thank you for the help, I am new to this, and building my first panel for controlling a tank farm. I'm a chemist, but these controllers are great. Now I am going to begin designing some test equipment. I really do appreciate the help, Thank you Joe Quote Link to comment Share on other sites More sharing options...
