ET200SP F-DI 8x24VDC HF - Profisafe Address Assignment & Low Voltage Alarm

Dear Customer,

I understand you're facing issues with the ET200SP F-DI 8x24VDC HF card, specifically regarding Profisafe address assignment failing and receiving a "low alarm supply voltage" despite confirmed voltage levels. This can be frustrating, let's troubleshoot this.

Here are potential causes and solutions:

• Profisafe Configuration: Verify your Profinet configuration in TIA Portal. Ensure the Profisafe address is not already assigned to another device.
• Hardware Compatibility: Confirm the card's firmware and hardware are compatible with your Profinet controller and TIA Portal version.
• Alarm Supply Issue: Even with correct voltage, check for voltage ripple or insufficient current capacity on the 24VDC supply. A failing power supply can cause this alarm.
• Card Diagnostics: Use TIA Portal diagnostics to check the card's internal status for more detailed error messages.

For detailed troubleshooting steps and FAQs, please refer to these resources on SiePortal:

• ET200SP F-DI 8x24VDC HF - Profisafe Problem
• ET200SP Low Voltage Error despite Correct Voltage

If these steps don't resolve the issue, please provide your TIA Portal version, card firmware version and a screenshot of the error message for further assistance.

Best regards,

Compatibility of New I/O Modules with Existing S7-400 System

Dear RH,

You are correct; the ET200SP I/O modules and IM 155-6AU00-0CN0 are obsolete, and compatibility verification in TIA Portal is limited without the database. However, based on Siemens documentation and known compatibility rules:

• AI 6ES7134-6GF00-0AA1 & AO 6ES7135-6HD00-0BA1 with IM 155-6AU00-0CN0: These new I/O modules are not directly compatible with the older IM 155-6AU00-0CN0. The newer modules require a newer IM (like IM 155-6PN) supporting PROFInet over Ethernet.
• Adding a New Profi-node: Yes, adding a new Profi-node with a new IM (IM 155-6PN) is the recommended solution. Both the old IM (155-6AU00-0CN0) and the new IM (155-6PN) can coexist on the same S7-400 rack, operating as separate PROFIBUS and PROFINET nodes respectively.

Compatible AI/AO Options (with Existing IM):

Finding non-obsolete AI/AO modules fully compatible with the 155-6AU00-0CN0 is challenging due to its age. Consider these options, but verify current availability:

• AI: 6ES7134-6FB00-0AA0 (If still procurable)
• AO: 6ES7135-6FB00-0BA0 (If still procurable)

Important Resources:

• Siemens Support - ET 200SP Compatibility
• ET 200SP – Important information on spare parts and system expansions

For a definitive compatibility check and detailed system integration planning, I recommend consulting a Siemens solution partner.

Sincerely,

ET200SP CPU (1510) and S2 Redundancy

Yes, the ET200SP CPU (1510) supports S2 redundancy and can directly join a PROFINET ring without needing a PN/PN coupler.

Here's a breakdown:

• S2 Redundancy: Requires a redundant PROFINET interface on each device and supports full and fast-acting redundancy.
• ET200SP CPU (1510): Possesses the necessary PROFINET interfaces to participate in an S2 redundancy setup.
• PN/PN Coupler: While a PN/PN coupler works, it's not *required* when using an ET200SP CPU (1510) due to its native S2 capability.

For detailed configuration information, please refer to the Siemens documentation:

IPC677E & ET200SP Communication Issue - Hardware Component Error

Dear Luis,

The error "A hardware component is or was inserted, but an error has occurred during module parameter assignment" with the ET200SP Server module typically indicates a configuration mismatch or communication issue beyond just the module name.

Here's a focused troubleshooting approach:

1. PROFINET Interface Configuration: Verify the IP address, subnet mask, and PROFINET interface configuration (e.g., Media Redundancy, VLAN) on both the IPC677E (Port 2) and the ET200SP Server module are correctly set and compatible.
2. ET200SP Configuration: Double-check the ET200SP configuration in the TIA Portal hardware configuration. Ensure that all modules (even the single Server module currently) are correctly configured with valid addresses and parameters.
3. Firmware Compatibility: While you've verified firmware matches, confirm the firmware versions of all components (IPC677E, ET200SP, Server module) are compatible according to the Siemens Compatibility Tool.
4. Communication Settings: Confirm that the correct communication protocol (PROFINET) is selected and configured correctly in both the IPC677E and the ET200SP.
5. Diagnostics: Utilize the TIA Portal's diagnostic tools to pinpoint the communication problem. Specifically, examine the PROFINET diagnostics for errors or warnings.

Further support and detailed troubleshooting steps can be found on the Siemens Support website:

• TIA Portal: How to diagnose PROFINET communication?

If the problem persists, please provide the TIA Portal project (sanitized if necessary) for detailed analysis.
