We create customized individual software for the highest demands in industrial production environments.


Whether with PI System or SSRS, we make your data talk – so that the basis of your business decisions is always reliable.


Highly qualified employees support your project around industrial IT and OT. From PCS 7 to Crystal Reports, we are your partner.


Sometimes an idea becomes a project and hence a product –
like LogOnPlus – the turbo for login/logout and control signatures in production applications.

The Hub in the Pharmaceutical Industry

MES / PLS Data Integration Layer

In the course of many years, we have established ourselves a name industry-wide with our expertise and solutions for MES/PLS data interfaces and integration.

Our adapter toolbox consists of generic communication services for a stable, reliable and fail-safe implementation of data exchange between MES and PLS/DCS systems in compliance with ALCOA guidelines.

Thus, our adapter toolbox is the modular basis and the “integration layer” for Industry 4.0  communication services.

Some projects successfully accomplished

A selection of our capabilities

MES / PLS Interface

Client: Biopharma
Technologies & Products: C#, SQL, SSRS, OPC

We designed and created the required applications, services and databases, which together represent the crucial interface between the Honeywell Experion DCS used by the customer and the Körber PAS-X MES. The interface thus forms the link between MBR, batch operation in the DCS and seamless documentation for the EBR in the MES. Without this integration layer “nothing works”.

PAS-X MSI historian data transfer

Client: Biopharma
Technologies & Products: PAS-X MSI, REST API, ODBC

As a certified Körber Ecosystem Partner, we developed an application for data transfer between PAS-X and a Historian system via ODBC using the manufacturer-open MSI interface to PAS-X. This application can be used to query individual values or aggregated values from the past in the Historian system from the MES.

SSRS Reporting from OSIsoft PI Data

Client: Pharma
Technologies & Products: PI System, SSRS

Generation of a larger number of validated (GAMP-5) batch reports according to customer specifications based on production rates continuously recorded via the PI system. The reports are generated via SQL Server Reporting Service. The underlying PI system itself was also set up by us and is permanently maintained, optimized and extended by various interfaces.

Test Bench Automation

Client: Pharma
Technologies and Products: NI LabView, Beckhoff EtherCAT, ADCO digital controller, C++

A laboratory test stand for a dry powder inhaler was automated with LabView and Beckhoff EtherCAT. The customer now can freely specify the test sequences and  parameters in a user-friendly manner and thus perform even complex and long test cycles fully automated. Accumulated  measured values are recorded and made available for test result evaluation.

PCS7 Project Support

Client: Chemistry
Technologies & Products: Siemens PCS 7

Ongoing support of multiple productive plants in all aspects of automation using PSC7 Batch. We support our customers in the areas of DCS detailed planning, automation concept, PCS7 Batch, fail-safe, DCS configuration and process visualization.

Microsoft Azure Cloud Services

Technologies & Products: MS Azure, Kubernetes, Docker, Power BI, Power Apps

Architecture Design, Development and Operation of Industry 4.0 solutions.
Certified (e.g. MS certified Azure Administrator Associate) employees provide support with the transformation of your IT & OT and prepare it  to get fit for the future.

The Turbo for Login Processes and Control Signatures:


… is the name for our standard software, which greatly accelerates personalized logon and logout processes at applications in production, such as MES, PLS, SCDA etc. Thanks to LogOnPLus, the number of manual entries for login and control signatures is drastically reduced. Countless operators appreciate this already every day.

Smart ID Methods

LogOnPlus (easily) recognizes operators e.g. via the existing RFID plant (factory) ID or biometric features (Fingerprint RFID or iris scan).

Time Saving and Convenience

… by passwordless logon (SLS), idle logout, Master / Slave groups, automatic logout when leaving the station and much more.

Flexible and Modular

LogOnPlus uses your existing Active Directory as user database and already supports many target applications and (RF) ID devices.

What’s an obion, after all?!?

Company obion will follow into the footsteps of the engineering company i.p.a.s.-systeme and will continue all business activities formerly established by i.p.a.s.-systeme.

In the many years of its existance from 1995 until 2023 under the guidance of its owner Bernhard Wurm, i.p.a.s.-systeme has become a well-renowned name within the field of software development, generating among its clients such associations as “reliable”, “safe” and “stable”. The development of our software has always been based on our highest claim to be perfect in application and absolutely reliable in operation – something you really can count on.

Like i.p.a.s.-systeme in its time, obion is just a made-up word, a synonym for an enterprise, just a name. However, behind a name there are always individual human beings – and in our case – a whole team enjoying to be part of it, and thus, being successful in its ambitions and achievements. Our team likewise in i.p.a.s.-times presently feels well-associated with our customers, highly motivated and result-oriented – over quite a long (-lasting) period of time.

It is these long-term and stable connections that we always have been striving for – within our team, with our partners and with our customers.
