Modern Controls Architecture

TAC develops PLC, HMI, and SCADA software for industrial machines and process systems with a strong focus on Structured Text, object-oriented programming, and modular software design. Our primary development environment is Beckhoff TwinCAT, which aligns well with the software methods we use to build scalable and maintainable control systems.
For complex equipment, software structure has a direct impact on commissioning, diagnostics, and future development. TAC applies a disciplined programming approach based on reusable function blocks, defined interfaces between subsystems, and state-based control methods that support clear machine behavior. This creates software that is easier to service, easier to extend, and better suited to long-term operation.
PLC, HMI, and SCADA Development
Under PLC programming, TAC provides development across the full controls layer, including machine control, operator interface, and supervisory systems. That includes PLC logic, HMI development, and SCADA functionality, allowing us to deliver a more complete and consistent controls solution from field devices to operator visibility.
Our work regularly includes machine sequencing, motion integration, safety logic, alarms, diagnostics, recipe handling, status visualization, and system-level control coordination. By developing these systems together, TAC helps ensure that the operator interface and supervisory functions are aligned with the underlying machine logic, reducing confusion during startup and improving long-term usability.

Platform Expertise and Software Quality
Beckhoff TwinCAT is our primary development environment and the platform where we bring the deepest level of expertise. TwinCAT is especially well suited to the software methods TAC prefers, including Structured Text, object-oriented programming, modular design, and advanced machine control. In addition to Beckhoff, TAC also supports Siemens Maple Systems and all CODESYS platforms for both new development and controls modernization projects.
Where appropriate, TAC also applies unit testing methods during development to validate software behavior before startup. Testing logic in a structured way helps catch issues earlier, reduce commissioning risk, and improve confidence when software is updated or expanded over time. The result is controls software built not only to run the machine, but to support the full life of the system.
