PLC Programming for Industrial Automation Systems
PLC Programming, Troubleshooting & Modernization
Proces-Automatik develops, programs, and supports PLC-based automation systems for industrial facilities, utility infrastructure, and process plants across Denmark and the Nordic region.
Programmable Logic Controller
Comprehensive PLC Solutions from Concept to Long-Term Support
We work with both new installations and modernization of existing systems — supporting projects from software development and commissioning to troubleshooting, migration, and long-term operational support.
Our experience includes industrial production, district heating, water treatment, pumping stations, and energy infrastructure where stable operation and maintainability are critical.
Industrial operators
PLC software for manufacturing & process facilities
Utility infrastructure
District heating, water treatment & pumping
OEMs & integrators
PLC engineering across vendor platforms
Lifecycle support
From development to reliable long-term operation
Industrial Control
PLC Programming for Process Plants &
Industrial Facilities
Reliable PLC systems require more than software development alone. Stable operation depends on well-structured control logic, clear alarm handling, reliable industrial communication, and systems that can be maintained and expanded over time.
We develop PLC solutions for both standalone machines and larger process facilities where multiple systems, operators, and supervisory platforms need to interact reliably in daily operation.
Projects often involve modernization of existing automation systems where new functionality must be integrated while production and plant operation continue during migration and commissioning.
Process
How we deliver
01
Specification
Map process logic, I/O, alarms, interlocks and operating modes.
02
Programming
Develop structured PLC code with clear alarm handling and communication layers.
03
Commissioning
FAT, SAT, on-site testing and operational handover to production teams.
04
Operation & support
Remote diagnostics, optimization and long-term lifecycle support.
Operational Support
Troubleshooting, Support & Remote Access
Operational issues in industrial environments often require immediate response.
Through secure VPN access and remote diagnostics, many faults can be identified and resolved without unnecessary downtime or on-site intervention. We support troubleshooting, commissioning, optimization, and modification of existing PLC systems across a wide range of industrial applications.
For facilities requiring on-site support, we assist throughout Denmark with fault-finding, commissioning, and operational troubleshooting.
Remote diagnostics
Secure VPN access for rapid fault-finding without downtime.
On-site support
Engineering assistance throughout Denmark when needed on the floor.

Control Technologies
PLC Systems & Industrial Automation
PLC systems are used to control, regulate, and monitor industrial processes, machines, and infrastructure.
Modern PLC platforms have replaced large relay-based control systems and today form the foundation of most industrial automation environments — from process control and machine operation to energy systems and utility infrastructure.
We work across multiple PLC platforms depending on operational requirements, existing infrastructure, and long-term maintenance considerations.
Phased migration
Replace legacy controllers while production keeps running.
Better diagnostics
Improved alarm handling, trending and operator overview.
Cross-platform
Choose the right PLC platform for the operation, not the other way around.

- Modernization of legacy PLC systems
- Troubleshooting and fault-finding
- Commissioning and FAT/SAT support
- Industrial communication and network integration
- Process optimization and operational improvements
- Integration between PLC, SCADA, and external systems
- Support for utility and energy infrastructure
FAQ
Engineering Insights
The questions we get from operators, utilities and project managers — most weeks.
What industries do you work with?
Most PLC projects involve industrial production, utility infrastructure, district heating, water treatment, and process facilities where stable operation and operational continuity are essential.
Do you support legacy PLC systems?
Yes. Many industrial facilities still operate on older PLC platforms that have become difficult to maintain or expand. We support migration, modernization, and staged upgrades while maintaining operational stability during transition.
Do you provide troubleshooting and remote support?
Yes. Through secure remote access we can often diagnose and resolve operational faults quickly without unnecessary downtime or delayed response times.
Which PLC platforms do you support?
We work across multiple PLC platforms depending on the existing installation, operational requirements, and long-term maintenance strategy of the facility.
