RFQ GUIDANCE
Common Questions
These answers explain what to send for product identification, documents, compatibility questions and quotations.
Can you identify a Siemens MLFB from a nameplate photo?
A clear nameplate photo can help us identify the product. Type every visible order number, suffix and hardware version because a partial identifier may refer to several variants.
Can you assess an alternative from the product family name alone?
No. Send the complete installed model. We must compare the electrical, mechanical, communication, firmware and engineering requirements before discussing a possible alternative.
What should I send for a Siemens PLC fault?
Send the complete CPU and module order numbers, LED states, error codes, diagnostic-buffer messages, recent changes and a short description of when the fault occurs.
What details can I send without remote access?
Send model identifiers, recorded symptoms, error codes, document needs and quotation questions. Qualified personnel must carry out electrical tests, program changes and work inside control equipment.
Can I request a manual or datasheet?
Yes. Include the full model, product generation and required language. Document availability depends on the identified product.
How do I request a quotation after model identification?
Send the complete order number, quantity, required condition and delivery destination. Availability, lead time and commercial terms are confirmed for the specific quotation.
How are packing and shipment details confirmed?
The delivery method, transport details and schedule are confirmed with the quotation and pro forma invoice for your destination.
How do I report a problem after delivery?
Send us your order number, part number and a description of the problem. Email photos of the product, nameplate or packaging, or send them through WhatsApp.
