For example, if you use the Advantys configuration software to calibrate an offset
of +64 at 4 mA and a max count of 31 744 at 20 mA, the system could be
represented as follows:
Here are some current representations after calibration with offset and max count:
Offset and RTP:
The offset parameter is represented as a signed 16-bit number. To access it using
RTP, write the following values to the RTP request block:
