Who is A&C?
A&C Automationssysteme & Consulting GmbH was founded in 1979 as Leo Stadlmayr Electrical & Control Systems.
We are an engineering office in the field of industrial system automation and we offer our services worldwide. Our expertise spans many different industries and automation systems and our range of services is continually expanding.
Our services
A&C provides E/I&C services in the field of industrial system automation. Our services include consulting, hardware- and software-Engineering, turnkey-projects, interfaces, … More


Our systems and tools
Over time, we have continually expanded the portfolio of systems and tools we use. Browse here for an overview.
Turnkey projects
In addition to the services described above, A&C also delivers turnkey projects. These could be, for example, process control systems with several process controllers and server-client systems for operation and data archiving, PLC-based machine controllers, migrations… More


Migrations
Experience shows that production machines and processing systems often have a longer lifecycle than the switchgear and systems controlling them. Spare parts are not available or can only be found used, there is no scope for expansion, or maybe you have plans to implement new functions. We offer a comprehensive range of services for plant modernisation. A new switching station and the automation it brings can considerably improve machine availability and yield… More
Industrial networks
When it comes to networks, our expertise lies in ensuring the stability, security and reliability of automation networks, both from controllers to servers and from servers to operating stations. We started focusing on these aspects quite some time ago, when we witnessed the increasing need for “outside” access… More


Software applications
We develop control applications working from written or verbal functional descriptions, functional plans, interlock diagrams, or old control applications.
A&C takes verbally communicated functional descriptions and writes them out before presenting them to the customer or operator for checking and confirmation. Pure migration projects … More
Hardware planning
At the beginning of each project, we run through all important points of the plant design in a face-to-face meeting with our customers. The experience of our engineers gives them the benefit of transdisciplinary thinking. Thus during the detail planning, they know which other trades to take into consideration… More


Consulting
A&C assists its customers throughout the entire course of an E/I&C project – in greenfield and brownfield projects alike. We survey the initial situation of an existing plant and determine what measures will be necessary… More
Robotic
Whether in assembly, palletizing, stacking, parts handling, packaging, painting, welding, cutting, … . Robots are virtually indispensable in production, logistics or the laboratory environment, … More

A&C offers these services either on a per-item basis or in the scope of a clearly defined, fixed-cost project. We work with the common CAE systems, process control systems (PCS) and programmable logic controllers (PLC) and primarily in the paper, steel, plastic and coatings,
cement, automotive, intralogistics/conveyor technology and woodworking industries. Through our activities in these areas, we also amassed a great deal of experience in the industries of energy, wastewater treatment and continuous processes in general.
In addition to the services described above, A&C also delivers turnkey projects. These could be, for example, process control systems with several process controllers and server-client systems for operation and data archiving, PLC-based machine controllers, migrations (e.g. replacing an outdated controller with a successor model or a PLC from another manufacturer), integration of new machine parts into existing process control systems, or even customer-specific camera/sensor-based inspection systems.
Process control systems
A&C plans hardware and software solutions to meet the customer requirements and specifications. Control, periphery and computer cabinets are planned by A&C and built by longstanding partner firms. The latest in process control systems even facilitate this process with OS-level virtualisation capability. We can furthermore compare the pros and cons and the pricing differences between virtualisation and a conventional environment, to help the customer decide which system is best suited.
After the engineering phase, A&C prepares the corresponding test environment as a simulation or in actual hardware, and runs through the testing of this environment together with the customer. Once all tests have been successfully passed, the commissioning phase begins.
We like to include our customers throughout the multiple phases of engineering, testing and commissioning – on the one hand because it keeps the project costs low and, on the other hand, because it greatly facilitates future maintenance and minor adaptations to the process control system for the customer.
PLC, machine control systems
Just as with process control systems, A&C plans the hardware and software according to customer requirements and specifications. Control and periphery cabinets are planned by A&C and built by longstanding partner firms. Built-in control panels or PCs are employed as user interfaces.
Testing and inspection machines
Depending on our customers’ requirements, A&C creates concepts for testing and inspection machines based on cameras or sensors. These are either integrated into ongoing production processes (with a connection to existing controllers, process control systems or OPC servers) or installed as standalone solutions with their own controller and operating unit – always depending on what the respective customer needs or the production process demands.
QCS, cross-machine and machine direction profile control
Originally developed for coating board web for beverage packaging, our PCS-7-based cross-machine and machine direction profile control is now universally used in both paper and board machines. A&C’s QCS application is programmed in SCL. While it has so far been used predominantly in PCS 7 environments, the code can also be ported to other PCS or PLC environments.
Experience shows that production machines and processing systems often have a longer lifecycle than the switchgear and systems controlling them. Spare parts are not available or can only be found used, there is no scope for expansion, or maybe you have plans to implement new functions. We offer a comprehensive range of services for plant modernisation. A new switching station and the automation it brings can considerably improve machine availability and yield.
We offer fixed price migrations for conveyor, bottling, bag-filling and palletising plants, saw equipment or sawmills and sorting machines.
Document revision
Migration is the perfect time to bring all documents up to date. A&C updates your existing electrical documentation or assembles new switchgear with subsequent replacement.
Adaptation of the operational and safety concept
When changing the software of a plant, it is also crucial to re-evaluate the dangers for the operating personnel. It is also a good occasion to adapt and amend the operational concept.
Reprogramming and expansion
The key point of migration. A&C specializes in adapting old systems to the latest state of the art. Contaminated sites are cleaned up, processes are optimized and new system functions are added, e.g. to facilitate access for maintenance personnel.
Interfaces to other systems
Naturally, the existing systems have to get along well with the “newcomers”. A&C adapts and tests all interfaces to make sure this is the case.
