Also known as: CPU222, CPU-222
The Siemens 6ES7212-1BB22-0XB0 is the SIMATIC S7-200 CPU 222 with AC power supply, 8 digital DC inputs and 6 relay outputs. The CPU has 4 KB program memory and 2 KB data memory, can be extended with PROFIBUS DP via an expansion module and is programmed with STEP 7-Micro/WIN; the relay outputs switch both DC and AC loads. EAN 4025515162643. Siemens keeps this type as a spare part, reports it as no longer available and discontinued it on 15 March 2017; the successor is the 6ES7212-1BB23-0XB0. When replacing, load the program from Micro/WIN or the memory cartridge, carry over the removable terminal strips with their wiring, carry over the mains connection and set the PPI address. Mind the order number: the DC/DC/DC version with transistor outputs is not interchangeable with this AC/relay version.

Faults and fixes 6ES7212-1BB22-0XB0
Problems with 6ES7212-1BB22-0XB0: 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.
6ES7212-1BB22-0XB0 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 6ES7212-1BB22-0XB0?
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 6ES7212-1BB22-0XB0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6ES7212-1BB22-0XB0 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 6ES7212-1BB22-0XB0 still available?
Not new from the manufacturer any more: the 6ES7212-1BB22-0XB0 was discontinued since March 2017. Van Haelen supplies it refurbished and tested.
What is the successor of the 6ES7212-1BB22-0XB0?
According to the manufacturer it is the 6ES7212-1BB23-0XB0. 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.
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.
