6ES7214-2AD23-0XB0

Product information

The 6ES7214-2AD23-0XB0 is a Siemens SIMATIC S7-200 CPU 224XP compact unit with DC power supply, 14 digital inputs and 10 digital outputs at 24 V DC, plus 2 analog inputs and 1 analog output. Work memory is 16 KB for program (12 KB with active run-time edit) and 10 KB for data, and the CPU provides two PPI / user-programmable interfaces.

The XP designation in the S7-200 range indicates the version with analog channels integrated on the CPU — the analog inputs and output shown above are part of the unit rather than added modules. Bit-operation time is 0.22 µs maximum, and 256 counters are available.

Specifications as published in Siemens product data for this article number. Verify against the nameplate of the unit offered to you.

Lifecycle status

Siemens product data identifies this article number as a spare part. The S7-200 range belongs to an earlier controller generation and is no longer actively produced, so replacements for existing machines come from surplus supply. Where a machine still runs on S7-200, the CPU 224XP with its integrated analog channels is one of the more sought-after parts of that range.

Typical applications

• Small machines and stand-alone equipment still running on the S7-200 platform
• Applications using the integrated analog channels without additional modules
• Replacement units where the existing program and wiring must remain valid
• Spare-part stock for installations where the S7-200 CPU is a single point of failure

Application examples describe typical uses of this product type. Suitability for your own installation must be confirmed against your engineering documentation.

Frequently asked questions

Does the CPU 224XP have analog channels on board?
Yes. The XP version includes 2 analog inputs and 1 analog output as part of the CPU unit.

Is a battery required to retain the program?
No. The program is maintained without a battery, with an optional battery module available for extended data buffering.

How many communication ports does it have?
Two PPI / user-programmable interfaces.

Which S7-200 software programs this CPU?
The S7-200 is programmed with STEP 7-Micro/WIN rather than TIA Portal. Confirm the toolchain version for your project before commissioning a replacement.

Is this part still produced?
Siemens lists it as a spare part; the S7-200 range is an earlier generation no longer actively produced.

What is the price and lead time?
Confirmed individually against current availability and quantity.
