Installation Structure 
Purpose
You can use this component to manage technical and billing data as well as period consumption of devices.
Features
Technical data
Device allocations describe dependencies of devices with other devices, such as meters controlled by ripple control receivers or a group of transformers connected to a meter.
Register relationships describe the relationships between registers. The registers can belong to different contracts. The following relationships are taken into account when creating a meter reading order:
Allocation of active registers to reactive registers for calculating the cosine phi
Serial switching of several registers (primary/secondary meter relationships)
Linking of registers to different usage types (on-peak/off-peak check)
Control relationships
Special relationships for allocating thermal gas factors
Logical registers describe the allocation of a certain task to a register and are most important in device replacement. The register of the old device must have the same logical register number as the register of the new device because
billing data is copied to the new register
the billing component must recognize which register is to take over the role of the old device (especially in the case of demand values)
Billing data
Rate data is dependent on the installation and therefore can only be maintained if the device is allocated to an installation. You can maintain rate data such as:
The relevance of a register to billing
The rate type of a register
The price class
Period consumption
The period consumption is used to determine the expected meter reading of a register for a certain date if meter reading results
Are not yet available, such as in the case of initial data creation
Cannot be used, for example if there is a change of tenant
Are to be ignored, for example if the customer has a complaint regarding budget billing
