01Product Overview

Siemens 6ES7214-1BG40-0XB0 is a SIMATIC S7-1200 CPU 1214C compact controller in the AC/DC/relay configuration. It combines an 85-264 V AC power input with 14 integrated 24 V DC digital inputs, 10 relay outputs, two 0-10 V analog inputs, 150 KB of work memory, and one PROFINET interface. The integrated architecture supports compact automation systems while retaining expansion options for additional signal and communication modules.

Configuration ControlMatch the complete article number, AC supply, relay output architecture, firmware, project version, I/O wiring, expansion modules, communication settings, and approvals before replacement.

02Functions

Control and Communication

  • Executes LAD, FBD, and SCL user programs for sequencing, interlocking, and machine-control tasks.
  • Integrated high-speed counters support fast pulse acquisition within the documented input limits.
  • PID control, frequency measurement, and controlled-positioning functions are available in the CPU platform.
  • The PROFINET port supports controller and device operation, SIMATIC communication, open Ethernet communication, and the integrated web server.
  • An OPC UA server is supported when the required Siemens runtime license is installed.
  • Diagnostic LEDs, diagnostic buffer, status and control functions, forcing, and trace recording support commissioning and maintenance.

04Compatibility

  • Use this exact AC/DC/relay variant when the installed system requires an AC-powered CPU with 24 V DC inputs and relay outputs.
  • Do not substitute the DC/DC/DC article 6ES7214-1AG40-0XB0 without redesigning the power and output wiring.
  • The current firmware record requires the corresponding supported STEP 7 environment; confirm the installed firmware before downloading the project.
  • Verify every signal module, communication module, signal board, HMI, drive, PROFINET device, memory card, web-server setting, certificate, and user-access configuration.
  • PROFIBUS operation requires the appropriate Siemens communication module, such as the documented master or slave option.
  • Preserve the IP address, PROFINET device name, hardware configuration, technology objects, passwords, certificates, retentive data, and time settings during replacement.

05Applications

Typical Uses

  • Compact machine automation that combines 24 V DC sensors with relay-switched loads.
  • Packaging, conveying, material handling, pump, fan, and process-skid control.
  • Networked control systems using PROFINET I/O, HMI, drives, and open Ethernet communication.
  • Counting, positioning, frequency measurement, PID, and diagnostic functions within the documented CPU limits.

Selection Boundary

  • Confirm load voltage, current, relay life, contact grouping, switching frequency, protection, and interposing-device requirements.
  • Check the permitted installation orientation, ambient temperature, enclosure, grounding, and separation requirements.
  • Treat application examples as selection context, not as proof of compatibility with a specific machine.

06Lifecycle

  • Siemens lists 6ES7214-1BG40-0XB0 as the conditionally compatible successor to the earlier 6ES7214-1BG31-0XB0; migration must still be engineered and tested.
  • Back up the complete TIA Portal project and document the CPU firmware, protection settings, memory card, module layout, network configuration, and field wiring before exchange.
  • Check program-memory requirements and current STEP 7 support before moving a project from an earlier CPU release.
  • After replacement, verify diagnostics, AC supply, sensor supply, digital and analog inputs, every relay output, communications, HMI, drives, alarms, interlocks, and the complete machine sequence.
  • A move to another S7-1200 electrical variant or to S7-1200 G2 is an engineered migration, not a direct part-number substitution.

FAQFrequently Asked Questions

What is Siemens 6ES7214-1BG40-0XB0?

It is a SIMATIC S7-1200 CPU 1214C compact controller with an AC power input, 24 V DC digital inputs, relay outputs, analog inputs, and PROFINET communication.

What power supply does this CPU require?

The documented permissible supply range is 85-264 V AC at 47-63 Hz. The installation and protective devices must follow the Siemens hardware requirements.

What integrated I/O is provided?

The CPU provides 14 integrated 24 V DC digital inputs, 10 integrated relay outputs, and two integrated 0-10 V DC analog inputs.

Which engineering software applies to the current firmware record?

The current Siemens data sheet identifies firmware V4.7 and STEP 7 V20 or higher. Confirm the actual firmware on the installed CPU before opening or downloading the project.

Is 6ES7214-1AG40-0XB0 a direct wiring replacement?

No. The 1AG40 version uses a 24 V DC supply and transistor outputs, while 1BG40 uses an AC supply and relay outputs. Any substitution requires electrical and project review.

What should be checked after replacement?

Verify diagnostics, supply voltages, digital and analog inputs, relay outputs, PROFINET communication, HMI and drive links, technology functions, alarms, interlocks, and the complete machine sequence.
