Plant iT

Process control software that is configured rather than programmed

ProLeiT, a software company in Herzogenaurach, Germany, makes Plant iT, a process control and manufacturing execution system for process industries. The company describes its philosophy as parameterisation instead of programming. In practice, engineers configure pre-built automation objects for each plant rather than writing control code from scratch, and ProLeiT says this keeps projects predictable and makes later changes easier to manage. The system runs on PLC hardware from several major controller makers, and the company names Schneider Electric, Siemens and Rockwell Automation among them. ProLeiT presents its approach as an alternative to simpler HMI and SCADA packages, which it says display a process without managing batches, recipes and materials in a structured way.

Modules for batches, recipes and materials

Plant iT is assembled from modules that can be added as a plant grows. Plant Direct iT handles process control and includes a Visu-Recorder, which lets a team step back through a run and find out what went wrong. Plant Batch iT is the batch system, built around a batch orchestration core, and the company says it follows the ISA-88 batch standard. Plant Liqu iT manages continuous recipes and routing. Plant iT material covers raw materials, stocks, warehouses and inventories, together with order and batch management. Plant iT connect is a configurable communication interface for linking the system to other software, and the archive manager keeps large volumes of production data for investigations that look back over long periods.

Tracking production and managing energy and lines

Above the control layer, Plant Acquis iT gathers production data for tracking and tracing, specifications and order management, and presents results in interactive analytics dashboards. Its energy management module captures energy data, analyses it and feeds it into the process control system. Its line management module plans job orders and packaging materials. Plant Integrate iT brings batch cockpit views and workflow management together in one place.

Breweries, dairies and the wider food sector

ProLeiT's brewing range carries the brewmaxx name. It includes energy and line management modules, a Visu-Recorder, maintenance functions, equipment modules, routing management, an integration layer, workflow tools and a batch cockpit, all designed for breweries. The company says brewing, dairy, beverage and food producers form its core market, and that the company counts more than 2,100 production facilities in over 110 countries as users of its systems. It describes itself as one of the world's principal suppliers of control system solutions for the food and beverage industry, which is the company's own claim rather than an independent ranking.

Training, partners and the 2026 release

ProLeiT runs training courses on its control and MES products, along with control technology, databases and high-level programming languages. It also runs partner programs for system partners, plant manufacturers and original equipment makers, and it works with scientific partners. The company says it has grown with its customers for more than 30 years and is marking 40 years in 2026. Its latest release, version 9.91 of Plant iT and brewmaxx, adds centralised user management across systems, more flexible process and cleaning functions, and a line management option for smaller applications. The firm plans to show a new generation of automation software at the BrauBeviale trade fair.
