Hello, do you have a PLC connected to the G120 which read the data? Christoph |

Siemens support was kind enough to supply me with the answer, so ill share it with those who need it: The parameters, when sent to a telegram, are scaled. The CU240E-2 manual can be used to find out which parameters correspond to one another. When you look up your read parameters there is a reference to the scaling parameter. r27 has scaling parameter p2002, r66 has scaling parameter p2000 and r72 has scaling parameter p2001. The value in the scaling parameter is the always the 100% value of this parameter. For example, suppose a situation where your current r27 = 500 A and you have 1000 A in p2002 as your reference current. When you send this in a telegram you will get +50% encoded in hexadecimal which will be 2000h. |
