hi estebangast, the simultaneator is easy. just switch the pumps on when a level is reached. For LL pump1, for L1 pump2, etc. The level sensors don´t switch off when they reach a higher level, or do they? I guess your alternator should guarantee an even load on the pumps, right? For this pupose I would count the pumps runtime and always switch the pump with the lowest runtime on. Maybe you can also do this in the other way and everytime a pump needs to switched off, you switch the pump with the highest runtime. there is a block in the Library for basic processes that should match this requirement: Library of Basic Processes (LBP) for TIA Portal V17 (STEP 7 Basic / Professional, WinCC Comfort / Professional, WinCC Runtime Advanced / Professional), WinCC V7.5 SP2 and WinCC Open Architecture 3.18 with documentation, libraries and demo projectshave a look the block "LBP_Aggr8–Control of up to 8 Aggregates":
hope this helps, regards, |

IMHO, you should do one step past combinatorial logic and get familiar with Finite-State Machines. Then you should be able to design a thing doing exactly what you want. Or at least understand the attachment. The chart is not finished, ellipsis shows where. AttachmentFSM example.pdf (111 Downloads) |
