Faults and fixes 6ES7412-1XF04-0AB0
Problems with 6ES7412-1XF04-0AB0: INTF or EXTF is on
INTF is an internal fault (CPU, firmware, program), EXTF an external one (a module, a station or the bus). The diagnostic buffer in STEP 7 names the cause and the module involved. BUS1F and BUS2F indicate a PROFIBUS or PROFINET fault on that interface.
6ES7412-1XF04-0AB0: BATF LED, program lost after a power loss
The S7-400 keeps work memory and retentive data with a backup battery in the power supply module (PS405/PS407). BATF or a battery message means it is flat: replace the lithium battery while the supply is on, otherwise the program is gone after the next power loss. If the program is on a FLASH card, the CPU reloads it from there.
What do I check when replacing a 6ES7412-1XF04-0AB0?
Check the firmware and product version on the rating plate against the project, carry over the memory card and download the program again. For CPUs in an H system (414H, 417H) make sure both CPUs run the same firmware and check the synchronisation modules.
Fault not fixed: replace, exchange or repair the 6ES7412-1XF04-0AB0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6ES7412-1XF04-0AB0 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.
