How the adaptive map controller works: from connection to the learned map
From measurement to optimal oxygen setpoint – automatically and transparently
The principle
The adaptive map controller (amc) creates a multidimensional map that relates process variables to the optimal oxygen setpoint. This map is continuously updated during operation and adapts to changing conditions – with proven effect on plants of up to 1 million PE.
The amc needs just three measurements
Only three input values are required to calculate the optimal oxygen setpoint
Ammonium (NH4)
The NH4 measurement is the central control variable. It indicates the current biological load and largely determines the oxygen demand in the aeration tank.
Inlet flow
Inlet flow signals hydraulic changes – such as during rain events. The amc detects load peaks early and proactively adjusts the setpoint.
Wastewater temperature
Temperature significantly affects nitrification performance. The amc automatically accounts for seasonal variations in its map.
Integration into the automation system
The map controller is integrated alongside the existing setpoint control. In case of faults or deactivation, the previous control takes over automatically – maximum safety with zero risk. Which interfaces and system requirements this needs is described in detail on the technology page.
Integration in 4 steps
Analysis & planning
We analyze your plant and define the optimal interfaces. Your existing infrastructure is taken into account.
Hardware installation
The industrial PC is integrated directly into the process level via standard interfaces (S7, Modbus TCP, BACnet).
Commissioning
The map controller immediately begins building plant knowledge. Initial optimizations occur within a few hours.
Continuous optimization
The map is continuously updated and automatically adapts to changing operating conditions.
Frequently asked questions
Do I need historical data for commissioning?
No. The map controller learns exclusively during operation and builds its plant knowledge from scratch.
How quickly will I see results?
Initial optimizations are performed within just a few hours of operation. The map continuously refines itself.
Is an internet connection required?
No. The map controller runs on a local industrial PC in the plant's control cabinet. It requires neither a cloud service nor an internet connection and can run entirely inside an isolated OT network – no process data leaves the site. This matters for operators who, under NIS2 or their own IT policy, do not permit external data connections out of the process network.
Which interfaces are supported?
The map controller supports S7 communication (PROFINET), Modbus TCP/IP, and BACnet – the common industry standards.
How long does installation take?
Installation and commissioning can typically be completed within 1–2 days.
Does the controller need manual readjustment?
No. The map controller automatically adapts to changed conditions – even when plant modifications occur, such as a new compressor.
