Compatibility and replacement
A SIMATIC memory card is required and is not included. Firmware and TIA Portal versions must match the project; send us the firmware version on the old CPU label.
Before you replace it
- Compare the full order number 6ES7511-1CK01-0AB0 with the label on the old unit, including the last digits (they identify the version).
- Check the supply voltage and wiring of the old unit before installing the new one.
- Note the firmware version printed on the old unit; TIA Portal or LOGO! Soft Comfort must support it.
Frequently asked questions
Is the memory card included?
No. The S7-1500 CPU needs a SIMATIC memory card, ordered separately.
Which software do I need?
TIA Portal with STEP 7 Professional in a version that supports the CPU firmware.
Can I get a price and delivery time?
Prices are quoted on request. Send the order number, quantity and delivery country on WhatsApp and we will reply with price and delivery time; air shipping is usually 5 to 7 days once ready, with a 1-year warranty.
Before you order
Compare the complete order number on the old unit with this page, including the suffix: in most ranges the last characters set the coil voltage, current range or version. If the label is worn, send us a photo and we will identify the part.
RendatSP ships from Yiwu, China, to factories worldwide; air delivery usually takes 5 to 7 days once the part is ready. The part is new and original with a 1-year warranty (shipping, payment and warranty). For a quotation, message us on WhatsApp with the order number and quantity. We also have agents in Saudi Arabia, Iraq, the UAE, Egypt, Oman, Libya, Morocco, Mauritania, Yemen, Algeria and Jordan.
