DMC's Software Approach

Ladder Logic in WinCC PLC Programming Code Example

We focus on well-designed and structured, modular PLC code appropriate for any factory. Our reusable code utilizes function and class-based architectures and adheres to IEC 61131-3 standards including structured text, function blocks, and sequential flow charts. The benefit is a flexible system that is easier to understand, debug, and modify for future needs.

We have libraries of previously developed, reusable code available for new systems that help reduce development cost and time.
