Sale and repair of SIEMENS SIMATIC S7-1200 parts

PLC for machines and smaller automation systems

SIEMENS SIMATIC S7-1200 is a compact modular PLC system designed for controlling standalone machines, production equipment and smaller automation systems. The CPUs feature integrated digital and, depending on the version, analog inputs and outputs, a PROFINET interface and technological functions.

The system can be expanded with additional digital and analog I/O, communication interfaces, technology modules, signal boards and accessories according to the requirements of the application.

CPU 1211C, 1212C, 1214C, 1215C and 1217C

In the SIMATIC S7-1200 CPU category, we offer compact CPU 1211C, CPU 1212C, CPU 1214C, CPU 1215C and CPU 1217C controllers. The individual versions differ in memory capacity, integrated I/O, expansion options, communication features and processing performance.

We supply standard CPUs, fail-safe versions and SIPLUS models for demanding environmental conditions. When selecting a CPU, we verify the full order number, power supply, output type, required configuration and the TIA Portal version used.

Digital inputs and outputs

For connecting pushbuttons, limit switches, sensors, contactors, valves and other devices, we supply digital input modules, digital output modules and combined digital input and output modules.

Our range includes SM signal modules and compact SB signal boards installed directly in the front of the CPU. We will help you verify the number of channels, voltage level, transistor or relay outputs and electrical compatibility with the connected equipment.

Analog inputs and outputs

For measuring and controlling process variables, we offer analog inputs, analog outputs and combined analog input and output modules.

We supply modules for voltage and current signals, RTD resistance sensors, TC thermocouples and the measurement of temperature, pressure, flow, level, power and other process values.

Communication modules and connection of other devices

SIMATIC S7-1200 communication modules enable the PLC to be connected to other control systems, drives, measuring equipment, serial interfaces and industrial networks.

We offer CM communication modules, CP communication processors and CB boards for PROFINET, PROFIBUS, RS-232, RS-485 and other industrial interfaces. Before selecting a module, we verify the required protocol, communication method and compatibility with the specific CPU.

Power supplies, accessories and software

For assembling or repairing a complete system, we also supply power supplies, accessories, connectors, memory cards, interconnection components and spare parts.

For PLC programming and diagnostics, we offer STEP 7 Basic software and TIA Portal licences. We will help you verify the appropriate software version according to the CPU type, firmware and existing project.

SIMATIC S7-1200 G2 is not hardware-compatible with the original series

SIMATIC S7-1200 G2 is a new generation of compact PLCs offering higher performance, more memory and expanded communication, diagnostics, safety and motion-control capabilities.

S7-1200 G2 components cannot be directly combined with hardware from the previous S7-1200 generation. In many cases, the original PLC program can be migrated with minor modifications, but the hardware configuration, modules, technology functions and TIA Portal version must always be checked in advance.

Repairs and replacement of faulty S7-1200 parts

We professionally repair, diagnose and functionally test CPUs, communication modules, power supplies and other SIEMENS equipment. When repair is not possible or economical, we check the availability of an identical part or recommend a suitable replacement.

When replacing a CPU, we can also help verify the memory card, firmware, configuration and possibilities for transferring the original PLC program to the replacement device.

How do you correctly identify the required S7-1200 part?

Send us the full SIEMENS order number, including all characters after the hyphen. For CPUs, we also recommend attaching a photo of the nameplate showing the device type, power supply, hardware version and firmware version.

When looking for a replacement for a faulty part, please also include a brief description of the fault, the TIA Portal version used and information about the other modules in the configuration.

Can the original S7-1200 be replaced with the new S7-1200 G2?

Yes, many applications can be migrated to the new generation, but this is not a direct one-for-one hardware replacement. A new hardware configuration must be designed, the program functions checked and the project configuration in TIA Portal modified.

Do you also supply older and discontinued S7-1200 parts?

Yes. We source older and discontinued components through a network of verified European warehouses. Depending on availability, we can offer a new, refurbished or used part or assess the possibility of repair or a suitable replacement.
