Key Features and Technical Specifications
The 6GK5602-0BA10-2AA3 supports transfer rates of 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s. This flexibility allows integration into various network speeds. The module operates on a 24 V DC supply voltage, with an acceptable range of 19.2 to 28.8 V DC. Maximum current consumption is 0.5 A.
- Firewall: Stateful inspection ensures traffic is monitored and filtered based on connection state.
- Address conversion: NAT/NAPT enables multiple devices to share a single public IP address.
- DHCP server: Automatically assigns IP addresses to devices on the internal network.
- SNMP v1 and v3: Supports network management protocols for monitoring and configuration.
- Syslog: Provides system logging for auditing and troubleshooting.
- PPPoE: Supports Point-to-Point Protocol over Ethernet for broadband connections.
- Dynamic DNS: Allows dynamic IP address updates for remote access.
- Symbolic names: Simplifies IP address management with human-readable names.
Power loss at 24 V DC is typically 6.72 W. The module includes a non-replaceable melting fuse (F 3 A / 32 V) at the power supply input. It also supports redundant voltage supply connections for increased reliability.
Applications and Use Cases
In manufacturing plants, it secures communication between PLCs and HMIs. For utility networks, it guards against external threats while maintaining data integrity. Moreover, its compact design suits space-constrained control cabinets. The module also supports static IP routing, enabling efficient data flow between subnets.
With a wide operating temperature range of -40 to +60 °C, it performs reliably in harsh environments. The module meets EN 61000-6-4 and EN 61000-6-2 standards for emitted interference and immunity. It also holds hazardous zone approval per EN 60079-0 and EN 60079-15, making it suitable for explosive atmospheres.

Installation and Setup
Mounting the 6GK5602-0BA10-2AA3 is straightforward. It supports screw mounting on horizontal and vertical surfaces. Additionally, it can be mounted on a 35 mm DIN rail, S7-300 rail, or directly on a wall. The compact dimensions (60 mm width, 125 mm height, 124 mm depth) allow flexible placement.
Configuration is performed using the Security Configuration Tool (SCT), which is included in the scope of delivery. This tool simplifies setting up firewall rules, NAT/NAPT, and other security features. Ensure the supply voltage is within the specified range to avoid damage. Use the 4-pole terminal block for power and the 2-pole terminal block for the signaling contact.
Maintenance and Reliability
Regular inspection of the module's connections and LED indicators helps maintain optimal performance. Since the fuse is non-replaceable, avoid overloading the power supply. The module's IP20 protection class requires installation in a clean, dry enclosure. Periodically verify that the firmware is up to date to benefit from security patches. Following the manufacturer's manual ensures safe operation and longevity.
What Is the 6GK5602-0BA10-2AA3?
When industrial networks face unauthorized access, the 6GK5602-0BA10-2AA3 delivers robust protection. This Siemens SCALANCE S602 module is designed to safeguard devices and components in intrinsic safety automation technology. It also protects industrial communication with a built-in firewall. Additionally, it offers address conversion (NAT/NAPT), a DHCP server, Syslog, symbolic names for IP addresses, PPPoE, DYNDNS, and SNMP (V1+V3).
Engineers rely on this module to segment internal and external networks. It provides two electrical connections: one for the internal network and one for the external network. Each connection uses an RJ45 port. The module also includes a signaling contact and a power supply connection.

Compatibility and Integration
The module integrates with Siemens SCALANCE family and other industrial Ethernet devices. It supports standard Ethernet protocols, making it compatible with existing network infrastructure. The C-PLUG removable storage allows easy configuration transfer and replacement. With SNMP v1 and v3, it works with common network management systems.
Troubleshooting Common Issues
If the module fails to power up, check the supply voltage and fuse. Ensure the terminal block is securely connected. For network connectivity issues, verify the RJ45 cables and port status. If firewall rules block legitimate traffic, review the configuration in SCT. Use Syslog to diagnose security events. For persistent problems, consult the official Siemens documentation or contact AutoDCSTech.
