Code generation for PLC software and machine controls

With NexaCode's code generation, you can automate the creation of recurring basic functions for PLC software in a structured and vendor-independent manner. This quickly produces a runnable basis with uniform modules, clear interfaces, and clean software architecture for Siemens, Rockwell/Allen-Bradley, and CODESYS.

Overview

Automate the Creation of Recurring PLC Functions and Set Up Projects Faster

NexaCode's code generation automates the creation of recurring software components that are typically needed in a similar form across many machine and plant projects. Instead of manually programming identical basic functions repeatedly, these are consistently generated and embedded in a clear software structure. The approach follows the principles of established PLC standards: clear blocks, defined interfaces, reusable program patterns, and a traceable structure. This provides development projects with a robust foundation for further engineering steps early on.

Core Functions

Functions of Code Generation at a Glance

Routine relief
Automated Generation of Recurring Functions
Typical basic functions such as I/O mapping, device connection, alarms, states, operating modes, manual functions, or diagnostic structures are created automatically. This saves time and reduces manual routine work in PLC engineering.
Structural clarity
Standardized Modules and Interfaces
Generated code follows a clear structure with defined interfaces, naming conventions, and building block patterns. This keeps the software consistent, readable, and easier for different project stakeholders to understand.
Agility
Quick start for project-specific process logic
Because the basic architecture is already in place, the team can focus on the actual machine function sooner. Individual processes, step sequences, and customer-specific features can be added selectively, instead of having to build standard functions first.
Integration capability
Suitable for structured, cross-vendor workflows
The logic behind the code generation aligns with modern engineering workflows featuring standardized data, templates, and exchange formats. This creates a better foundation for reuse, reviews, and consistent project handovers.
Your Benefits

Why Automated Code Generation Pays Off in
Projects



Code generation accelerates the creation of boilerplate code, reduces repetitive tasks, and frees up more time for project-specific logic.

Time-saving
Significantly faster to the first runnable software base
Recurring basic functions are not developed anew each time, but are generated in a structured way. This shortens the project's ramp-up phase and allows the team to move more quickly into implementing the actual functions.
Quality Assurance
Fewer errors in routine parts of the software
Where less manual copying, adapting, and rewriting occurs, the risk of inconsistencies, forgotten adjustments, and typical copy-paste errors in standard modules also decreases.
Regulatory compliance
Consistent software quality across multiple projects
A generator always creates the same basic patterns according to defined rules. This makes the quality of recurring software components more stable, more comprehensible, and easier to verify.
Easy to maintain
Improved maintainability and faster onboarding
Consistent structures, clean naming conventions, and recognizable building blocks facilitate maintenance, service, and onboarding. New team members or external partners can also find their way around the software more quickly.
Future viability
Stronger foundation for variants and follow-up projects
Those who develop machine families, modular systems, or recurring customer types benefit particularly strongly. New variants can be built faster and more controllably on an already proven software basis.
Typical Applications

Typical Use Cases for Code Generation

Automated code generation is particularly useful in projects where software components are repetitive yet need to remain cleanly scalable.

Examples:

  • Development of standardized PLC basic architectures for new machine projects

  • Fast project start for OEMs with similar machine modules and variants

  • Uniform software basis for multiple programmers, teams, or locations

  • Reduction of manual routine work for I/O, alarm, diagnostic, and operating mode logic

  • Preparation of reusable standards for subsequent plants, product platforms, and retrofit projects
User

For whom code generation is particularly relevant

This module is particularly interesting for:

  • Machinery and plant manufacturers

  • PLC Programmer

  • Technical Leads and Software Owners in Automation

  • Companies with recurring machine standards or product platforms

  • Teams that want to implement multiple projects in parallel with consistent software quality

Code Generation as an Implementation Lever within NexaCode

Within NexaCode, standardization defines the rules, structures, and patterns. Code generation then operationally implements these specifications, creating a directly usable software foundation. Project-specific process logic is built upon this foundation, while scalability ensures that standards remain viable long-term across variants, subsequent projects, and extensions. This transforms code generation from a black box into a controlled engineering tool: standardized where repeatability makes sense, and flexible where machine processes must remain individual. Simultaneously, this creates a software foundation that significantly better supports reviews, quality checks, and future extensions than inconsistently developed project structures.
