Overview
The CPU 1214C is the most common S7-1200 variant in Vietnamese machine building: enough on-board I/O for a typical packaging or conveyor machine, a PROFINET port for HMI and remote I/O, and six high-speed counters for encoders and flow meters. The DC/DC/DC version (24 V supply, 24 V inputs, transistor outputs) is the right choice for fast switching and PLC-to-PLC signal exchange; choose the AC/DC/Rly variant (6ES7214-1BG40-0XB0) when you need relay outputs or 230 V supply. Programmed in TIA Portal STEP 7 Basic or Professional, it expands with up to 8 signal modules, 3 communication modules and one signal board.

Frequently asked questions
Is the 6ES7214-1AG40-0XB0 a direct replacement for the older 6ES7214-1AG31-0XB0?
Yes. The -0XB0 firmware V4 CPU replaces the V3 (-1AG31) in the same footprint. Programs must be migrated in TIA Portal V13 or later; V3 projects open and compile with minor adjustments. We can check your project before you order.
Is the 6ES7214-1AG40-0XB0 available from stock, and what is the lead time?
Availability of the SIMATIC S7-1200 CPU 1214C DC/DC/DC changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the 6ES7214-1AG40-0XB0 genuine, and what documentation comes with it?
We supply only genuine Siemens products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the 6ES7214-1AG40-0XB0 outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the 6ES7214-1AG40-0XB0 is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
