Hello 8Noodles, Thanks for replying! I don't have problems with connection between WinCC and PAC3200. How I mentioned above, some of the parameters values (Ea and Er) don't correspond. And my question is, what should I do to solve this problem? |

I don't know why the reply value is zero when you interpret the data as 64bit floating point, but it is very likely 64 bit floating point. Siemens' Magnetic Flowmeter Mag6000 Modbus RTU uses the same terminology - double - for its 64 bit floating point totalizer register, (4)03015, as shown in the screen shot below: [snip] I had to decode the value from a Mag 6000 using a web calculator https://www.binaryconvert.com/convert_double.html because my Modbus client/master does not do 64 bit conversions, and the value proved correct. |

Hello jhonut, please look at this post Block library for reading out the values of PAC3200/4200 devices over Modbus/TCP regards |
