HelloDaniel Chartier I used this block for a flow totalizer and it works perfect but i have 4 flow meters. How i can use this block for each flow meters seperately. I cannot change the FB and DB blocks. When i try to change it is showing errors. I have 4 flow meter values and i need to totalize all at the same time but induvidually. So the output value should be in different addresses. I am totalizing the flow every second. The default blocks are FB100 and DB100. This i need to change for each flow meters.

Dear psvinesh, If you have difficulty of calling totalizer function block four times in your program in LAD simply insert 4 FB in 4 networks and simply change DB number for each block call.Check the following link to see how possible to use multiple instances. How do you create and update multiple instances? Best regards, Hamid Hosseini |

Dear, Daniel Chartier I used this block to calculate total flow rate m³/h interval time Hour and scan cycle 100ms as usedOB35 test block by flow rate value 60 m³/h that means that at the end of one hour total consumption rate will be 60 m³ but after testing at give me total value greater than 60 about 120 m³ but when decrease scan cycle (100 ms) the total value improve so decrease and increase until reach 1 ms which give me 63 m³ but I cannot decrease it below 1 ms where the error . |

dear hdhosseini, I did exactly step 3 in your comments but it gives me different values at the simulator and at actual test at cpu. input value 10 interval 1m cycle 100ms simulator give me correct values but when test at CPU give big values. regards,
