Siemens S7-1200 PLC Programming
We provide external engineering support for companies that design and build machines for sale (OEMs) as well as for manufacturing plants looking to modernize their machinery and automation systems.
As your “external automation department,” we take full responsibility for challenges related to Siemens S7-1200 PLC programming, machine safety (Safety Integrated), and integration with higher-level control and IT systems. We support you at every stage of the project – from offline software development, through industrial network configuration (PROFINET, Modbus), to on-site commissioning and start-up at the end customer’s location worldwide.
With a team of 35 full-time automation experts and experience gained in the demanding standards of the automotive industry, we deliver clean, well-commented code that is reliable, easy to diagnose, and ready for long-term operation.
Why involve our specialists in Siemens S7-1200 programming?
Your safety is our standard
In S7-1200 system design, not only hardware matters, but also continuity of engineering support.
Efficient communication and project management
Professional delivery process
Additional benefits for OEM machine builders
What we implement in Siemens S7-1200 projects?
Integrated TIA Portal engineering
We use the full engineering capabilities of TIA Portal (from V13 to the latest version), significantly reducing development and debugging time. A unified tag database ensures automatic synchronization between PLC and HMI.
PROFINET and industrial networks
We design efficient distributed I/O systems and integrate drives, valve islands, code readers, and vision systems into a single high-performance PROFINET network.
Modern HMI visualization (Basic & Comfort)
We design intuitive operator interfaces for SIMATIC Basic and Comfort panels, including process, diagnostic, and alarm screens for fast response and full machine control.
Safety Integrated technology
We implement safety logic using S7-1200F (Fail-Safe) controllers, integrating E-Stops, light curtains, and safety interlocks directly into the PLC program.
Advanced Motion Control
We deliver precise motion control using PTO outputs or PROFIdrive communication for servo drives and stepper motors, including axis configuration and positioning directly in the controller.
OPC UA communication (Industry 4.0)
We configure OPC UA servers for secure data exchange between machines and higher-level IT systems such as SCADA, MES, and ERP – without additional gateways.

Programming languages we use
At Amister, we adapt to your specific requirements: if you have your own established standards, we adhere to them rigorously; if not, we select the optimal solution for your specific process. When programming Siemens S7-1200 controllers, we utilize:
Ladder Diagram (LAD)
This is our primary choice for developing control logic and diagnostics. Ladder logic is the most intuitive language for electricians and automation engineers. It enables your technicians to instantly locate the cause of machine downtime by following logical “paths” directly within the code.
Function Block Diagram (FBD)
We use Function Block Diagrams to build modular, repeatable systems. This approach reduces implementation time—a logic block that has been tested once (e.g., for motor control or sensor handling) performs with the same reliability every time it is used throughout the program.
Structured Control Language (SCL)
SCL (the Siemens equivalent of Structured Text) is our “secret weapon” for complex data operations, recipes, and mathematical calculations. It is ideal for the S7-1200 and S7-1500 series, allowing us to implement functions that would be difficult to read or manage in a traditional ladder diagram.

Frequently Asked Questions – Siemens S7-1200 Programming
Do you provide S7-1200 programming and project execution on-site at the customer’s facility?
Yes. Our team supports clients at every stage—from offline software preparation and commissioning/testing at your assembly hall (OEM), to final startup and production assistance at the end-user’s site worldwide. We provide comprehensive Siemens S7-1200 programming, adapting to your machine build schedule.
Will my project be safe in the event of a programmer’s vacation or illness?
Will my project be safe in the event of a programmer’s vacation or illness? Definitely. At Amister, we utilize a substitution procedure—every S7-1200 programming project is assigned a Lead Engineer and a Backup Engineer. With a 100% full-time team of 35 automation engineers, we guarantee workflow continuity and constant code supervision without relying on the availability of external freelancers.
Do you perform Siemens S7-1200 programming according to specific standards (e.g., Automotive)?
Yes. We have extensive experience with rigorous industry standards such as VASS, Daimler Integra, and BMW TMO. If you have your own internal standard, we adhere to it strictly. If not, we select the optimal solution for your process (LAD, FBD, SCL) to ensure the S7-1200 programming results in code that is easy to diagnose.
Can the S7-1200 controller handle advanced Motion Control?
Yes. We utilize the full potential of this unit for precise control of servo drives and stepper motors via PTO outputs or Profidrive communication. We handle axis configuration and positioning directly within the controller.
Do you integrate Safety Systems as part of the service?
Yes. We design and implement complete safety logic based on Safety Integrated technology and S7-1200F (Fail-Safe) units. We integrate components such as E-Stops, light curtains, and safety locks directly into the PLC program. This allows S7-1200 programming to eliminate external safety relays and simplify the machine’s electrical structure.
Do you also design Operator Interfaces (HMI) for S7-1200 controllers?
Yes. We create modern visualizations for SIMATIC Basic and Comfort panels within the TIA Portal environment. Our interfaces are fully integrated with the controller logic, ensuring that Siemens S7-1200 programming goes hand-in-hand with intuitive and clear diagnostics for the operator.
Can you integrate S7-1200 with supervisory systems like MES/SCADA?
Yes. We use protocols such as OPC UA for secure data exchange with IT and ERP systems without the need for additional gateways. We configure and parameterize the communication to provide full production reporting for your company or your client.
Do you assist in hardware selection and architecture configuration before the project starts?
Yes. We act as your external engineering support right from the concept stage. We select the appropriate CPU and expansion modules. Our experience in Siemens S7-1200 programming allows us to precisely estimate hardware requirements so the system is not over-dimensioned in terms of cost.
Do you train employees on operation and diagnostics after implementation?
Yes. Every S7-1200 programming project concludes with technical staff training. We explain the program structure and HMI operation so that the maintenance or production team can independently respond to daily production challenges and instantly locate potential faults.
