What is the difference between Digital I/O and Modbus TCP for EoL testing with Hebabox / Hebastack ?U. Heitzmann2026-02-01T15:55:19+01:00

What is the difference between Digital I/O and Modbus TCP for EoL testing with Hebabox / Hebastack ?

Both Digital I/O and Modbus TCP can be used to integrate Hebabox / Hebastack into an End-of-Line (EoL) test system. The key difference lies in functionality, data depth, and scalability.

Digital I/O (discrete signals)

With Digital I/O, the Hebabox/Hebastack is controlled via simple binary signals (24 V inputs/outputs).

Typical use cases

Start / stop a test cycle
Reset
Output overall status signals such as Busy, OK, or NOK

Characteristics

Very simple and robust
No Ethernet or network configuration required
Limited to ON/OFF signals
No parameterization, detailed diagnostics, or measurement data transfer
Ethernet hardware is not required

Best suited for

Very simple EoL setups
Legacy systems
Applications with minimal functional requirements

Modbus TCP (Ethernet-based communication)

With Modbus TCP, the Hebabox/Hebastack communicates with the PLC via Ethernet using structured data registers.

Typical use cases

Start / stop and full control of test sequences
Parameterization (e.g. light values, modes, sequences)
Reading detailed status, diagnostics, and error codes
Logging and traceability in production systems

Characteristics

Significantly higher functional depth
Structured data exchange instead of single bits
Scalable and future-proof
Enables detailed diagnostics and transparency
Requires Ethernet connection and PLC-side Modbus implementation

Best suited for

Modern EoL production lines
Automated test systems with traceability requirements
OEM / Tier-1 environments

Which option do we recommend?

While both options are supported, we clearly promote Modbus TCP for EoL testing:

Higher functional value
More diagnostic and test content
Better scalability
Preferred and approved interface in BMW production environments

Digital I/O remains an option for minimal setups, but Modbus TCP is the recommended choice for professional, production-grade EoL testing with Hebabox and Hebastack.

Why does Hebatronic not offer LIN-based solutions?U. Heitzmann2026-01-29T16:00:37+01:00

Why does Hebatronic not offer LIN-based solutions?

Hebatronic deliberately does not offer LIN-based solutions because LIN is not technically suited for modern ILaS® / ISELED® lighting systems beyond basic control functions.

LIN was designed as a low-speed control bus for simple actuators and sensors. With a maximum data rate of approximately 20 kbit/s, LIN is well suited for commands such as on/off, dimming, or basic status signals. However, it reaches its technical limits very quickly when used for today’s dynamic, high-resolution LED lighting systems.

Modern ILaS® / ISELED® applications require:

High bandwidth for color and brightness data
Deterministic timing for synchronized animations
Scalability to hundreds or thousands of LEDs
Detailed diagnostic feedback at LED level

These requirements are structurally incompatible with LIN. Using LIN as a transport layer for ILaS® functions inevitably leads to compromises in performance, diagnostics, flexibility, and scalability.

Hebatronic therefore focuses on ILaS-native architectures, where lighting data is handled directly on the ILaS® bus and controlled via industrial, deterministic interfaces (e.g. PLC-based systems). This avoids inheriting the technical limitations of LIN and allows the full capabilities of ILaS® to be used without restriction.

In short:

LIN is suitable for controlling simple lighting functions.
ILaS® is required for driving complex, modern LED lighting systems.
Hebatronic designs its solutions around the requirements of ILaS®, not around the limitations of LIN.

This is a conscious architectural decision to ensure long-term scalability, diagnostic depth, and production robustness.

What is the difference between LIN and ILaS®?U. Heitzmann2026-01-29T14:48:52+01:00

What is the difference between LIN and ILaS®?

LIN (Local Interconnect Network) and ILaS® (Intelligent Lighting as a Service) are two fundamentally different communication systems used in vehicles, each designed for a specific purpose.

LIN is a classic, low-cost control bus. It was developed for simple actuators and sensors such as switches, motors, and basic lighting functions. LIN operates at a relatively low data rate and is mainly used to transmit control commands like on/off, dimming, or simple status information.

ILaS®, in contrast, is a high-speed bus specifically designed for modern LED lighting systems. It is optimized for ISELED®-based light modules and transmits synchronized color and brightness data to each individual LED in a chain. In addition, ILaS® enables detailed diagnostic feedback from every LED.

In short:

LIN is a control bus for simple functions.
ILaS® is a data bus for complex, dynamic LED lighting.

Key differences at a glance:

Data rate:
LIN ≈ 20 kbit/s · ILaS® ≈ 2 Mbit/s
Typical use:
LIN → basic control commands
ILaS® → high-resolution lighting data and animations
Scalability:
LIN → limited number of nodes
ILaS® → thousands of LEDs in a single chain
Diagnostics:
LIN → basic
ILaS® → detailed, per-LED diagnostics

In modern vehicle and EOL test architectures, both systems are often used together:
LIN provides the higher-level control or test interface, while ILaS® handles the precise distribution, synchronization, and diagnostics of the lighting system.

Typical EoL test functions include:

Deterministic initialization of the ILaS® bus
Automatic node detection (node count / presence check)
Verification of communication integrity and timing
Evaluation of module status and error conditions
Functional activation of light modules for GO / NO-GO decisions

Integration into the test system

PLC connection via Modbus TCP (recommended for maximum functionality and diagnostics)
Alternatively via Digital I/O for simple, minimal EoL setups

ILaS® stands for “ISELED® Light and Sensor” and is currently mainly used in the automotive sector, particularly by BMW in vehicles starting in 2025. With this fieldbus, not only can LEDs be controlled via the ISELED protocol, but sensors and actuators can also be integrated and read in any quantity and combination. With the continuously growing number of LEDs, especially in vehicles, significantly higher data rates for control and diagnostics can be realized.
