Scope of supply
We will confirm the specific scope of supply, packaging and any accessories in the quotation. For replacement CPUs, we will also check the memory card and other items needed for commissioning.
Frequently asked questions
Is the same product family enough to identify a replacement?
The complete order number is essential. If the type changes, compare the electrical and mechanical design, connections and requirements of the original application.
What must be checked for firmware and a STEP 7 or TIA Portal project?
Check the replacement unit's actual firmware and the availability of this exact CPU in the hardware catalog of your engineering version. TIA Portal support cannot be confirmed from the product family name alone. A change of CPU type normally requires modification or at least a thorough check of the project.
Does the memory card need to be checked?
Yes. Check the memory card type and capacity, program and data contents and the original CPU's backup arrangement. We will specify the required card and accessories in the quotation.
Can you assess a faulty part?
Yes. Send the complete order number and a description of the fault. We will check the diagnostic and professional repair options for your specific unit.
