Also written as: 6ES7 416-2XK04-0AB0, 6ES74162XK040AB0
Also known as: CPU416-2, CPU-416-2
The Siemens 6ES7416-2XK04-0AB0 is the SIMATIC S7-400 CPU 416-2 with 2.8 MB work memory (1.4 MB code, 1.4 MB data). The first interface is MPI/DP at 12 Mbit/s, the second a PROFIBUS DP interface; the 416-2 is the powerful CPU of the S7-400 for large plants with much distributed I/O on two PROFIBUS lines and extensive programs. EAN 4019169123563. Siemens keeps this type as a replacement part, reports it as no longer available and discontinued it on 4 February 2026; the successor is the 6ES7416-2XP07-0AB0. When replacing, load the program from STEP 7 or the memory card, check the backup battery in the power supply, set the MPI/DP and DP addresses and insert the CPU in the same slot of the rack; when moving to the successor, change the CPU type and the firmware version in the hardware configuration.

Faults and fixes 6ES7416-2XK04-0AB0
Problems with 6ES7416-2XK04-0AB0: 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.
6ES7416-2XK04-0AB0: 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 6ES7416-2XK04-0AB0?
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 6ES7416-2XK04-0AB0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6ES7416-2XK04-0AB0 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.
Frequently asked questions
Is the 6ES7416-2XK04-0AB0 still available?
Not new from the manufacturer any more: the 6ES7416-2XK04-0AB0 was discontinued since February 2026. Van Haelen supplies it refurbished and tested.
What is the successor of the 6ES7416-2XK04-0AB0?
According to the manufacturer it is the 6ES7416-2XP07-0AB0. A successor does not always fit an existing installation without changes; replacing like for like is often the fastest route. If in doubt, ask us.
Does the 6ES7416-2XK04-0AB0 replace the 6ES7416-2XK02-0AB0?
Yes. According to the manufacturer the 6ES7416-2XK04-0AB0 is the successor of the 6ES7416-2XK02-0AB0. Before replacing, check that the project and the connections match the new version; if in doubt we also supply the 6ES7416-2XK02-0AB0 itself, refurbished or new, as long as it can be found.
What does refurbished mean?
Cleaned, inspected, aged or critical components replaced and tested to our test protocol for this product family. You get a 24-month warranty, a test report and a serial number label.
Can I exchange or repair my faulty unit?
Yes. With an exchange Van Haelen supplies a refurbished unit straight away and you return the faulty one. With a repair you first get a diagnosis and then a fixed price, with test report and warranty.
