Each measurement value can be transferred in the following formats: byte, char, short, unsigned short,
integer, unsigned integer, float and double. Each measurement value can also be scaled.
Profibus
value = measurement value * scaling factor.
The byte index states the start byte of the variable in the
profibus string. After configuration, the changes must be transferred to the unit.
Profibus Address
If several units are connected with each other through the profibus interface, a master (PC, PLC) can
only differentiate this unit on the basis of the unit address. Each Power Analyzer must have a specific
unit address within the network. Profibus supports the unit addresses in the range 0 to 126. The
profibus address can be directly allocated using the display or using the configuration software
GridVis. The modbus and profibus addresses have the same parameters in the unit. On the display,
the address can be allocated using parameter 200 (UMG604). How to set the address can be taken
from the operating manual of the respective Power Analyzer. The address allocation is given using the
GridVis Software in the configuration as follows:
