Interfaces in automation: SMEMA and Hermes at haprotec

Automation in electronics manufacturing requires smooth communication between machines and systems. At haprotec GmbH, the focus is on the seamless integration of different processes in order to maximise efficiency and quality. Standardised interfaces such as SMEMA and the Hermes protocol, which enable optimal networking of production lines, are an essential part of this.

​
SMEMA interface: The industry standard for machine communication

The Surface Mount Equipment Manufacturers Association (SMEMA) developed one of the best-known standards for communication between machines in electronics manufacturing. The SMEMA interface enables machines from different manufacturers to be connected to each other to ensure a continuous production flow.

​

​The advantages of SMEMA at haprotec:
 

• Uniform machine communication: Machines can work together seamlessly, regardless of the manufacturer.

• Optimisation of material flow: Automatic transfer of printed circuit boards between individual production stations.

• Easy integration: SMEMA is widely used and standardised, enabling rapid implementation.

By using the SMEMA interface, haprotec ensures that various automation solutions can be efficiently integrated into existing manufacturing processes.

The Hermes Protocol: The modern alternative to SMEMA

While SMEMA relies on simple electrical signals for machine communication, the Hermes Protocol goes one step further. As the successor to SMEMA, it enables digital, network-based communication with advanced traceability and data management functions.

Features of the Hermes Protocol:
 

• Detailed component and product information: In addition to the pure transfer of printed circuit boards, product-related data is also transmitted digitally.

• Greater flexibility: Unlike SMEMA, Hermes allows for full network integration.

• Improved traceability: Production data can be recorded and processed in real time.

• Future-proof: Hermes is an open standard and supports Industry 4.0 applications. 

 
haprotec GmbH relies on the Hermes protocol to enable intelligent production control. By implementing this interface, machines can communicate with each other even more precisely and production data can be integrated into higher-level MES systems.

Integration into haprotec's central plant control system (ZLS)

To make the most of the advantages of both interfaces, haprotec integrates SMEMA and Hermes into its proprietary central plant control system (ZLS). The ZLS acts as a higher-level control and monitoring unit that manages all production data in real time. This creates a fully networked production system with maximum efficiency and transparency.


Customised interfaces for individual requirements

In addition to the established SMEMA and Hermes standards, haprotec also offers tailor-made interface solutions to meet specific customer requirements. These individual interfaces enable connection to proprietary machines, customer-specific MES systems or special automation solutions. This flexibility allows haprotec to ensure that even complex manufacturing environments are optimally networked. Particular emphasis is placed on scalability, future-proofing and easy maintenance.

​

By using standardised interfaces such as SMEMA and Hermes, haprotec ensures that machine communication in electronics manufacturing runs smoothly. While SMEMA stands for proven, simple machine communication, Hermes offers a future-proof solution for data-driven manufacturing. Combining these technologies with haprotec's ZLS enables optimised, flexible and transparent production.
