Product Information

Full details

The Siemens LOGO! CSM Ethernet Switch (6GK7177-1MA20-0AA0) is designed for industrial automation environments, enabling efficient network connectivity for LOGO! 8 logic modules. Its key benefit is providing a reliable, unmanaged 4-port Ethernet connection with easy DIN rail mounting and diagnostic LEDs. A potential caveat is its limited operating temperature range, requiring careful consideration in extreme environments. This compact switch offers auto-negotiation and auto-crossing for fast, configuration-free commissioning, supports SMS communication for remote monitoring, and integrates seamlessly with Profinet/Profibus.

FAQs

What is the maximum Ethernet speed supported by this switch?

The switch supports Ethernet speeds of 10/100 MBit/s.

Do I need to configure the switch?

No, this is an unmanaged switch and features auto-negotiation and auto-crossing, allowing for plug-and-play operation without configuration.

What is the required power supply?

The switch requires a DC supply voltage ranging from 12V DC to 24V DC.

Can this switch be used with devices other than Siemens LOGO! 8?

While primarily designed for LOGO! 8, it can function as a standard unmanaged Ethernet switch for any device requiring 10/100 MBit/s Ethernet connectivity, provided power and environmental conditions are met.

What is the operating temperature range?

The switch can operate in temperatures from 0°C to +55°C.

How many devices can be connected?

The switch has 4 RJ45 ports, allowing for the connection of up to 4 network devices.

What is the purpose of the front port?

The front port is designated for diagnosis, allowing for easier connection of a diagnostic device for troubleshooting or monitoring.

Troubleshooting

Device not powering on

Verify the DC power supply voltage is within the 12V-24V range and check that the power connections are secure.

No network connectivity

Ensure all Ethernet cables are securely plugged into both the switch and connected devices. Check diagnostic LEDs for link status. Test cables individually.

Intermittent network drops

Check for potential interference in the environment. Ensure cables are not damaged and connections are firm. Verify that operating temperature is within limits.

Diagnostic LEDs not indicating status correctly

Check power supply. If LEDs are still abnormal, try reseating the module or consider it may require service.

Pros and Cons

Pros

  • Simple, unmanaged plug-and-play operation requiring no configuration.
  • Compact design with DIN rail mounting for easy integration into control cabinets.
  • Diagnostic LEDs provide quick status checks.
  • Supports SMS communication for remote monitoring and control.
  • Offers auto-negotiation and auto-crossing for hassle-free setup.

Cons

  • Limited operating temperature range (0°C to +55°C) may not be suitable for all industrial environments.
  • As an unmanaged switch, it lacks advanced features like VLANs or Quality of Service (QoS).
  • Only 4 ports may be insufficient for very large or complex network setups.
  • Specific compatibility details with all Profinet/Profibus configurations should be verified.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely attach the switch to a standard DIN rail within your control cabinet.
  2. Power Connection: Connect a suitable DC power supply (12V DC to 24V DC) to the designated power terminals.
  3. Network Cabling: Connect your LOGO! 8 modules and other network devices to the 4 RJ45 Ethernet ports using standard Ethernet cables.
  4. Diagnosis Port: Connect a diagnostic device to the front RJ45 port for troubleshooting or initial setup if needed.

Compatibility:

  • Primary Use: Designed for use with Siemens LOGO! 8 series logic modules.
  • Network Protocols: Compatible with Ethernet standards and functions effectively within Profinet and Profibus environments as a network hub or LAN splitter.
  • Operating Voltage: Requires a 12V DC to 24V DC supply.

Care:

  • Cleaning: Disconnect power before cleaning. Wipe the exterior with a dry or slightly damp, lint-free cloth. Avoid using solvents or abrasive cleaners.
  • Environment: Ensure the switch operates within its specified temperature range (0°C to +55°C) and is protected from excessive dust, moisture, and vibration.
