Product Overview

6AG1214-2BD23-2XB0 is the SIPLUS CPU 224XP AC/DC/relay controller in the S7-200 family. It combines an AC supply with DC sensor inputs, relay switching outputs and integrated analog channels.

STEP 7-Micro/WIN provides the engineering environment for the controller. Expansion modules, communication settings and user-program capacity should be selected together for the machine configuration.

Ordering focus: Match the AC supply and relay-output version, then size the program, onboard I/O and expansion power budget.

Key Functions

Mixed-signal machine control

Onboard digital and analog channels handle discrete machine signals and analog process values.

CPU 224XP program execution

The processor executes Boolean instructions in 0.22 µs and provides configurable timers, counters and interrupts.

S7-200 communications and expansion

Two serial ports and support for up to seven expansion modules allow the CPU to form a larger S7-200 station within its power budget.

Frequently Asked Questions

Which software should I use to maintain a program in 6AG1214-2BD23-2XB0?

Use STEP 7-Micro/WIN for the S7-200 controller program and communication settings.

Can the relay outputs on 6AG1214-2BD23-2XB0 generate 100 kHz motion pulses?

High-speed pulse outputs require a DC transistor-output variant rather than the relay-output version.

How much program space remains when I enable RUN-mode editing on 6AG1214-2BD23-2XB0?

The program capacity is 12,288 bytes with RUN-mode editing compared with 16,384 bytes without it.

Can I add seven expansion modules to 6AG1214-2BD23-2XB0?

Up to seven expansion modules are allowed when the CPU and expansion-module power budget is sufficient.

Can I connect a SIWAREX MS weighing module to 6AG1214-2BD23-2XB0?

The CPU is a released SIWAREX MS host, while the weighing module retains its own environmental ratings.

Which serial modes can I use on 6AG1214-2BD23-2XB0?

The RS485 ports support PPI master or slave, MPI slave and configurable Freeport communication.

Does 6AG1214-2BD23-2XB0 provide analog I/O without an expansion module?

The CPU includes two analog inputs and one analog output.

Compatibility & Ordering Notes

Before ordering 6AG1214-2BD23-2XB0: Use the SIPLUS CPU 224XP AC/DC/relay variant and match the existing Micro/WIN project, serial network, relay loads and S7-200 expansion power budget.

Controller replacement preparation

• Provide the AC supply and 24 V DC input signals for this relay-output variant.
• Keep the program within the selected RUN-edit memory capacity.
• Match both RS485 ports to the existing PPI, MPI or Freeport settings.
• Calculate the expansion power budget and observe each attached module’s own ratings.
