Industrial PROFINET to EtherCAT converters for industrial automation integration

Industrial PROFINET to EtherCAT converters – what are they used for?

An industrial PROFINET to EtherCAT converter enables the integration of control systems based on the PROFINET standard with machines and devices communicating via the EtherCAT protocol. These converters are used in industrial automation wherever a PLC or higher-level control system operates on PROFINET, while field devices, drives, or I/O modules use EtherCAT.

Using a converter allows both communication standards to be connected without changing the existing system architecture. The PROFINET to EtherCAT converter acts as a protocol gateway, mapping process data from the PROFINET network into the EtherCAT data structure in a stable and predictable way.

How does a PROFINET to EtherCAT converter work?

On the PROFINET side, the converter is seen as a standard network device exchanging data with the PLC or control system. On the EtherCAT side, it operates as a real-time communication node, cyclically exchanging process data with EtherCAT devices.

PROFINET process data is mapped into the EtherCAT data area, allowing the control system to:

• read signals from EtherCAT devices,
• send control commands and parameters,
• monitor alarm and diagnostic states,
• integrate EtherCAT devices with PLC and SCADA systems.

Industrial PROFINET to EtherCAT converters provide consistent data exchange, even in installations with strict timing requirements and a large number of connected devices.

Where are PROFINET to EtherCAT converters used?

The PROFINET to EtherCAT converter is used in modern and upgraded industrial automation systems where different communication standards must be combined.

• Production lines and machinery: integration of EtherCAT devices with central PLC controllers operating on PROFINET.
• Retrofit and modernization projects: connecting EtherCAT-based machines to existing PROFINET installations without rebuilding the system.
• Process automation: communication between different network segments in distributed control architectures.
• Industrial plants: projects across Europe where mixed PROFINET and EtherCAT environments are common.

Using protocol converters makes it possible to preserve the advantages of both communication standards while simplifying system integration across the entire facility.

What features should an industrial PROFINET to EtherCAT converter provide?

When selecting an industrial PROFINET to EtherCAT converter, it is important to focus on features critical for reliable operation:

• deterministic process data mapping,
• full compatibility with PROFINET networks,
• support for cyclic EtherCAT communication,
• advanced diagnostics and error indication,
• industrial housing with DIN-rail mounting,
• reliable 24/7 continuous operation.

A properly selected PROFINET to EtherCAT converter enables secure system integration, shortens commissioning time, and increases the flexibility of industrial automation infrastructure.
