Hi, Sorry I was not complete about this... The LOGO! I'm using, is an 0BA6.
I've attached the scheme I would like to apply. It's an example diagram, but it shows what I'm trying to achieve:
I would like to achieve the same for the impulse relais: I would like to use I6 also to put the impulse relais in their "off" state (I already attempted to do that by "OR"-ing I6 and I3 to kick B005 again), but the problem is that I don't know for the moment how I (or better: the LOGO! system) can "remember" in what state the impulse relais are, the moment you push I6. Simply giving yet another impulse to the impulse relais using an OR-gate in combination with I1 - I3 is not wise (as I already did experimental wise with I3), since the impulse relaise might already be in the "off" state and in that case you would bring them back in the "on" state, which is absolutely not the purpose! I hope I made my goal clear. If more information is needed, pls. ask. Thanks in advance for your support guys! Best rgds, --Geert AttachmentExampleDiagram.zip (245 Downloads) |

Hi, I have a modified version, based upon some hints from Toeternietoe (although I'm not using an input to keep track of the state of the impulse relais, that seems to be impossible). Pls. have a look at the modified attached scheme. I've modified the first case (input I1) to see if this is a correct solution. It works, also in combination with my "general reset" input I6 (hence, the usage of the AND gate), but personally I have the feeling it looks like a very "expensive" solution with respect to function block usage. Any chance this can be made more "smart"? PS: there's still one synchronisation phase needed with this proposal, as suggested/mentioned by Marcjan. Best rgds, --Geert
