Faults and fixes 6ES7 516-3AN01-0AB0
Problems with 6ES7 516-3AN01-0AB0: ERROR LED red or flashing
A solid red ERROR LED indicates a fault that keeps the CPU in STOP (hardware, firmware or program); flashing red a fault the CPU reports while it keeps running. TIA Portal, Online & diagnostics, shows the diagnostic buffer with the cause. MAINT (yellow) is not a fault: maintenance requested, for instance a memory card running full.
6ES7 516-3AN01-0AB0 does not start or the project will not load
On the S7-1200 the program is stored internally and optionally on a SIMATIC Memory Card; on the S7-1500 the card is mandatory. Check that the card is inserted and not formatted as the program card of another CPU. If the project will not load, the CPU firmware usually does not match the version the TIA project expects: check the version in the device configuration.
What do I check when replacing a 6ES7 516-3AN01-0AB0?
Firmware version and issue must match the project; a higher firmware is usually fine after updating the version in TIA. Carry over the memory card or download again, and set the IP address and PROFINET device name again. Mind the protection level too: a CPU with access protection asks for the project password.
Fault not fixed: replace, exchange or repair the 6ES7 516-3AN01-0AB0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6ES7 516-3AN01-0AB0 refurbished (tested, with a test report per serial number) or new in factory packaging, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
