Hello, There is no possibility to read 64-bit floating point value directly. You should have some library made for this task. There is good example for S7-300 PLCs. By using this code you can make some library for S7-200. Anyway check your MAG8000 manual one more time. I do not know about MAG8000, but MAG6000 has total value represented by 32-bit floating point AND 64-bit floating point. I do not want to believe that there is no modbus register for 32-bit floating point total value. It should be. It's a common format. |

Hi, you can take a S7-1200. It can read 64bit values. Maybe you have the money, to upgrade your system. regards |
