Remote Access mit dem symmedia Hub – Sicherheit und Flexibilität für Ihre Maschinen

From diagnostics to configuration, the symmedia Hub ensures seamless and controlled access to machines and components, while meeting the highest technical and organizational security standards.

Secure Service Connect (SSC) – More Than Just Remote Access

The “SSC-Tunnel” delivers secure access to defined endpoints within a TCP/IP network, either on or behind the symmedia Edge Device. With the “SSC-Tunnel”, operators and service providers can connect to a wide range of components, including:

• HMI (Human-Machine Interfaces)
• PLC (Programmable Logic Controllers)
• Sensors and Gateways
• Industry PCs and Line Controllers

A key security feature of the “SSC Tunnel” is explicit access authorization, controlled by the operator on-site. This ensures that only authorized personnel can access the machine or component, significantly enhancing trust and security in remote access operations.

This makes remote access via the symmedia Hub exceptionally secure and reliable.

In connected systems, security is a critical factor that goes beyond purely technical measures. Organizational security also plays a pivotal role in ensuring trust and compliance. With its „security by design“ approach, the symmedia Hub addresses both technical and organizational aspects, offering key features essential for effective and secure remote access management.

Centralized Management of Configurations and Endpoints

All configurations and endpoints are securely stored in the symmedia Hub, rather than being scattered across service technicians’ laptops. This centralized approach offers significant security and operational advantages:

• Reduced Risk: Sensitive data is not stored on mobile devices, minimizing vulnerabilities in case of loss or theft.
• Streamlined Updates: Changes and updates can be made centrally and are immediately available to authorized users.
• Compliance and Traceability: Operators have full transparency over created connections and authorized endpoints, ensuring compliance and security audits are simplified.

SSC Data Link Tunnel – Deeper Insights and Enhanced Features

The “Data Link Tunnel” expands the functionality of the “SSC-Tunnel” by supporting Layer-2 connections, providing greater control and flexibility for advanced configurations.

Technical Aspects of Layer-2 Connections:

• With a Layer-2 connection, the machine controller is treated as if it were directly within the same local network as the user, as all Ethernet traffic (including broadcasts and MAC addresses) is transmitted.
• This is particularly useful when the machine controller uses protocols operating on the data link layer (Layer 2) or when specific devices need to be connected directly within a virtual LAN (VLAN).
• Such connections enable the use of protocols that rely on MAC addresses or broadcasts, which are commonly required for controllers or fieldbus communication.
• This setup is ideal for tools like TIA Portal or Twin CAT, which depend on specific network environments to function properly.

Advantages of Layer-2 Connectivity:

• Seamless Integration: No need for additional network adjustments.
• Optimized Performance: Direct and fast connections without extra configurations.
• Enhanced Security: Operators maintain full control over connections, as all remote access must be explicitly authorized.

Seamless Integration of Remote Access within the symmedia Hub’s Service Case Management

A key advantage of the symmedia Hub over other remote solutions lies in its seamless integration of remote access within the context of service cases. Unlike standalone remote access tools, the symmedia Hub connects remote diagnostics and troubleshooting directly to the service case management process. This ensures that every remote access session is fully documented, tied to a specific service case, and accessible to all authorized stakeholders.

By combining remote access with features like ticketing, chat, video conferencing, and whiteboarding, the symmedia Hub provides a collaborative platform where operators and service providers can work together in real time. This integration eliminates the need for switching between separate systems, reduces the risk of data silos, and ensures that service cases are resolved faster and more efficiently. Additionally, the ability to archive service case histories with detailed access logs enhances transparency, compliance, and continuous improvement in service management.

Financial Benefits of Secure and Efficient Remote Access

Remote access through the symmedia Hub doesn’t just enhance security; it also delivers measurable cost savings:

1. Reduced Travel Costs:

• • Service technicians can access machines globally without the need to travel, cutting costs for flights, accommodations, and expenses.
  • A reduction in travel also lowers the CO₂ footprint, supporting sustainability goals.

2. Increased Productivity:

• • Technicians can manage multiple clients remotely, boosting efficiency.
  • Faster resolution of issues minimizes downtime, improving overall equipment availability.

3. Optimized Resource Utilization:

• • Companies can rely on fewer on-site technicians, as specialists can connect to machines remotely from centralized locations.

Benefits of the symmedia Remote Access solutions

• Highest Security: Explicit access authorization and centralized storage of configurations.
• Centralized Control: All connections are managed and monitored through the symmedia Hub.
• Flexibility: Supports a wide range of endpoints and protocols, including Layer-2 connectivity.
• Cost Efficiency: Reduced travel expenses, increased productivity, and streamlined operations.
• Seamless Integration: Easily connects to tools like TIA Portal and Twin CAT for a direct Access into PLC’s.
