Product Overview
6ES7214-1AG40-0XB0 is a SIMATIC S7-1200 CPU 1214C DC/DC/DC — the mid-range S7-1200 CPU with integrated 14 digital inputs (24 V DC sink/source), 10 digital outputs (24 V DC sourcing transistor — 0.5 A per point), and 2 analog inputs (0–10 V, 12-bit + sign). It features a built-in PROFINET RJ-45 port (10/100 Mbps) for programming, HMI connection, and as an IO-Controller for distributed I/O (up to 16 devices). The CPU is powered by 24 V DC and supports up to 8 signal modules (SM), 3 communication modules (CM/CP), and 1 signal board (SB) onboard. Program memory is 100 KB, data memory 4 MB (retentive). Programming is via TIA Portal (STEP 7 V13+ / V17/V18). Suitable for machine control, packaging, material handling, and building automation.

Key Features
-
PROFINET Built-In: Native Ethernet for programming, HMI (Basic/Comfort panels), and distributed I/O — no add-on card required.
-
Transistor Outputs with PTO/PWM: Four 100 kHz PTO channels for stepper/servo motion control directly from the CPU.
-
Flexible Expansion: Add SM 1221/1222/1223 (digital), SM 1231/1232/1234 (analog), SB for extra I/O or analog in/out on-CPU, CM for serial/fieldbus.
-
Web Server & SNMP: Built-in web pages for diagnostics; SNMP for network monitoring — valuable in integrated plant IT.
-
TIA Portal Native: Fully integrated in Totally Integrated Automation Portal — drag-and-drop configuration, online diagnostics, trace functions.
Typical Applications
-
Packaging / Converting Machinery: Multi-axis servo/stepper via PTO + PROFINET HMI + remote I/O for ancillary stations.
-
Conveyor & Material Handling: Distributed control with ET 200SP/AL I/O via PROFINET; local DI/DO for start/stop/jog/estop.
-
Process Skid Auxiliaries: Small batch blending, CIP skid control — analog in for temp/pressure, digital I/O for pump & valve, PROFINET to DCS/MES.
-
Building Automation / HVAC: AHU/Chiller local control with BACnet or Modbus TCP via CP, or OPC UA (FW V4.2+ with license).
Variant note: DC/DC/DC = 24V DC powered, 24V DC inputs, 24V DC transistor outputs (this item). Other 1214C variants: 6ES7214-1BG40-0XB0 = AC/DC/RLY (120/230V AC power, relay outputs), 6ES7214-1HG40-0XB0 = DC/DC/RLY (24V DC power, relay outputs). For S7-200 legacy migration, the 1214C DC/DC/DC is the closest functional upgrade to a CPU 224XP DC/DC/DC.
