Siemens 6ES7 212-1BB23-0XB8 CPU 212 Compact PLC Module – SIMATIC S7-200 Series
When a compact PLC controller fails on the production line, the consequences are immediate: conveyor belts stop, packaging lines halt, and every minute of unplanned downtime translates directly into lost revenue and missed delivery commitments. In discrete manufacturing, food processing, and building automation environments, the CPU module is the brain of the entire control system — without it, no logic executes, no I/O responds, and no safety interlock functions. Sourcing a verified, compatible replacement quickly is not optional; it is operationally critical.
The Siemens 6ES7 212-1BB23-0XB8 is the CPU 212 compact controller within the SIMATIC S7-200 micro-PLC family — one of the most widely deployed small-scale automation platforms in global industrial history. With millions of S7-200 units installed across manufacturing plants, water treatment facilities, and OEM machinery worldwide, this CPU module remains in active demand for both new installations and legacy system maintenance. Its combination of onboard I/O, integrated RS-485 communication, and compatibility with the STEP 7-Micro/WIN programming environment makes it a reliable, cost-effective choice for engineers managing compact automation tasks.

Frequently Asked Questions
Q: Is the 6ES7 212-1BB23-0XB8 still in production?
A: The SIMATIC S7-200 series has been discontinued by Siemens, but the 6ES7 212-1BB23-0XB8 remains widely available as new-old-stock and refurbished units. Konmask.com maintains sourcing channels for this part.
Q: What programming software is required?
A: This CPU is programmed using Siemens STEP 7-Micro/WIN software. It is not compatible with TIA Portal, which is used for S7-300/400/1200/1500 series.
Q: Can this CPU communicate with a Siemens HMI panel?
A: Yes. The onboard RS-485 port supports PPI protocol, which is natively used by Siemens TD 200, TP 070, and compatible operator panels.
Q: What is the difference between 0XB0 and 0XB8 variants?
A: The suffix indicates the firmware/hardware revision. The 0XB8 is a later revision with minor improvements. Both are functionally compatible within the S7-200 ecosystem.
Q: Do you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, and certificate of origin upon request for all international shipments.
