Siemens SIMATIC is the core automation hardware platform within the Siemens industrial portfolio, covering programmable logic controllers, human-machine interface panels, distributed I/O systems, and associated accessories. The SIMATIC family spans multiple generations of SIMATIC S7 controllers, from compact S7-1200 CPUs to the modular S7-300 and S7-400 series, as well as a comprehensive range of SIMATIC HMI operator panels, including Basic Panels and Comfort Panels. With over 12,000 products in this collection, SIMATIC represents the broadest single product grouping in PLC Direct’s Siemens inventory.

PLC Direct supplies Siemens SIMATIC hardware to maintenance teams, procurement managers, and operations staff managing existing SIMATIC installations. Our collection covers S7-1200 and S7-300 CPUs, SIMATIC HMI panels across multiple display sizes and series, and SIMATIC S7 accessories, including memory cards and I/O modules.

Where Siemens SIMATIC Hardware Is Used

A failed SIMATIC CPU or operator panel in an active production line can halt operations entirely until a direct replacement is located. For facilities running S7-300, S7-400, or older S7-1200 hardware, OEM lead times for exact replacement units can stretch to weeks or longer, and in facilities dependent on continuous production, locating a direct replacement quickly is the priority.

Facilities that depend on Siemens SIMATIC hardware include:

Manufacturing plants running SIMATIC S7-300 or S7-400 PLCs for line control, where legacy hardware replacement is required to restore a specific machine configuration
Process facilities using SIMATIC S7-1200 CPUs for compact automation tasks requiring direct CPU replacements
Operations using SIMATIC HMI KTP Basic or Comfort Panel series for machine-level operator interfaces, where display or panel failures create operator visibility gaps
Food and beverage, pharmaceutical, and chemical plants running SIMATIC-based batch control systems
Water and wastewater utilities running distributed SIMATIC S7 hardware across remote pump stations.
Mining and heavy industry operations with SIMATIC-controlled conveyor, crusher, and pump systems

When an S7 CPU, HMI panel, or associated SIMATIC module fails in an installed system, having access to verified surplus sealed or refurbished stock outside standard OEM channels keeps the facility running.

Siemens SIMATIC Products

The SIMATIC collection spans SIMATIC S7 controllers, SIMATIC HMI panels, and SIMATIC accessories. All product families and model references below are confirmed on the live PLC Direct collection page.

What to Know Before You Buy Siemens SIMATIC

Ordering the correct SIMATIC replacement comes down to three variables: the hardware series, the specific model variant, and the hardware condition grade. Getting these right before placing an order avoids compatibility issues and delays in restoring the installed system.

Hardware condition options: PLC Direct supplies SIMATIC hardware in surplus, sealed, refurbished, and used conditions. Surplus sealed units are factory-sealed stock; refurbished units have been tested and restored to operational condition.

CPU compatibility: SIMATIC S7-1200 CPUs in this collection require TIA Portal V13 SP1 or later for programming. Before ordering a replacement CPU, confirm that the TIA Portal version available on the engineering station matches the programming requirement for the specific CPU variant being sourced.

HMI panel compatibility: SIMATIC HMI panels are configured using WinCC Basic (for KTP Basic panels) or WinCC Comfort (for Comfort Panel series). The configuration software version must be at or above the minimum version listed in the product specification. Replacing a panel with a different series or generation may require project adaptation.

Connectivity: Basic Panels in this collection use PROFINET only. Comfort Panels include both PROFINET and MPI/PROFIBUS DP interfaces, making them suitable for installations on legacy PROFIBUS networks as well as PROFINET architectures.

Warranty: All Siemens SIMATIC hardware purchased from PLC Direct includes a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.

Frequently Asked Questions

SIMATIC S7-1200 CPUs in this collection require TIA Portal V13 SP1 (also referred to as STEP 7 Basic V13 SP1) or later to program. This is a firm requirement noted directly in the product specifications. Earlier versions of STEP 7 or TIA Portal are not compatible with these CPU variants.

PLC Direct's SIMATIC collection includes SIMATIC S7-1200 CPUs across multiple variants (CPU 1214C and CPU 1215C), SIMATIC HMI panels including KTP700 Basic and Comfort Panel series (TP700, TP900, TP1200), SIMATIC S7 memory cards, and a broad range of additional SIMATIC S7 modules and accessories. The collection spans over 12,000 products. Contact us with a specific part number to confirm current availability.

SIMATIC HMI Basic Panels, such as the KTP700 Basic, support key/touch combined operation and connect via PROFINET only. They are configured using WinCC Basic or STEP 7 Basic. Comfort Panels support touch-only operation, offer higher color depth (16 million colors vs. 65,536), include both PROFINET and MPI/PROFIBUS DP interfaces, provide 12 MB of configuration memory, and are configured using WinCC Comfort. Comfort Panels are suited to applications requiring more complex visualizations or legacy fieldbus connectivity.

The S7-1200 CPUs confirmed in this collection carry PM300 (Active Product) lifecycle status, meaning they remain in current production at Siemens. Memory cards for the S7-1x00 platform in this collection carry PM410 (Product cancellation) status and are available as legacy replacements.

Yes. SIMATIC HMI Comfort Panels in this collection include both PROFINET and MPI/PROFIBUS DP interfaces, making them compatible with installations on existing PROFIBUS DP fieldbus networks. This dual-interface capability is specific to the Comfort Panel series; Basic Panels in this collection connect via PROFINET only.
