Assembly of the cyclical process image
In Slot 1 always the module ‘System state’ is present providing the following information:
Bit
Meaning
0
0: Measurement system stopped or not reachable
1: Measurement system running
1
0
↔
1: When the measurement system is running, the bit changes its state when the
value of at least one of the modules changes
2…31 not used, currently set to 0
Hints
A parameterization of the base functionality of the device (such as the measurement functionality)
via PROFINET is not required
A local modification of parameters (e.g. IP address, PROFINET device name) is not possible
6.7.3 Validity of measurements
The following measurements can be used in the process image:
•
Instantaneous values of voltages, currents, active/reactive/apparent power, frequency, load factor
•
THD voltages and currents, TDD currents
•
Odd harmonics of voltages and currents up to the 25
th
•
Symmetrical components and unbalance factors of voltage/current
•
Fundamental power, distortion reactive power, cos
ϕ
, tan
ϕ
•
Energy meters high and low tariff, pre- and user-defined base quantities
•
Mean-values, predefined power quantities and user-defined base quantities
The provided measurements are the sum of all possible values, for all system configuration from single
phase up to 4-wire unbalanced. The Modbus device description provides the information about the validity
of the measurements with respect to the used system configuration. This description can be downloaded
via one of the following sources:

If invalid measurements are used in the process image, their values are always zero.
