Hi, I am running into trouble, I'm quite new to PLC programming, I have only done process control in C langauge.. My project is as follows: 3 vessels / tanks needs to be filled with and amount of water 0-300Ltr only one tank must be filled at a time My input is a waterflow sensor which gives 1 ping per 1 Ltr. All of this works ok.. I think.. Maybe not the smartes way to do it but it seems to work, My problem is: How do get to skip filling tanks if my counter is set to zero in my TDE hmi ?? Any good ideas ? Attached file is my current program..

Here a possible suggestion. The value entered by TDE setpoint is checked for a permissible range (0-300). AttachmentEnabeling_filling.zip (135 Downloads) |

Here is another extended program with control of the pump and transferring the set point in the switch-off of the counter.

Hello Martin, Here another suggestion. I have considered manual filling mode, but it can be applied in your project. The filled water can be seen in TDE and basic module. If you don't already have a drain water measurement, the values remain even if a drain occurs. For instance, the counters values need to be reset manually (mathematic and analog trigger resets with counter reset automatically). In the future you can use a flow meter to substract values in the mathematic instructions. Regards AttachmentFillingcontrol V3 05 08 2016.zip (134 Downloads) |
