Measured Values

Reference

Note

Depending on the device composition not all of the indicated analog inputs (and cor-

responding IEC 60870-5-103 mapping entries) may be available in the SIPROTEC

device.

For the transmission of measured values, the compatible range and the private range

can be used. Are there several measurement telegrams parameterised then these are

transferred cyclically after each other.

Note

If all parameterised measurement telegrams aren't transferred, the parameter Scan-

ning period (in ms) for measurements must be put on a greater value.

The range of the values which can be transmitted is mostly +/-240% or +/-2.4 of the

rated value. The value in data unit 9 has 13 bit (1 sign, 12 bit data). That means that

+/- 4096 indicates +/- 240% of the measured value. Some following measured values

use a different definition:

• cos Phi: -4096 relates to cos PHI = -1; +4096 relates to cos PHI = +1

Changes of the scaling of the measured values are possible in adaptation to the con-

crete installation environment (ref. to manual "IEC 60870-5-103 Communication data-

base").
