What do you need help with?

New machinery needs control software

Turn machine requirements into tested PLC logic and operator screens. Siemens automation engineers support software development and commissioning alongside your machine builders, with clear interfaces to electrical design.

Machines need to exchange production data

Connect Siemens controllers to production systems or equipment from other manufacturers. Specialists define signal exchanges and diagnose communication faults, including failures between the PLC and supervisory applications.

Recurring faults need engineering attention

Address intermittent stops or unreliable machine sequences with S7 diagnostic support. An engineer traces the fault through controller logic and field signals, then tests corrections against operating conditions.

An existing control system needs upgrading

Prepare changes to legacy STEP 7 applications or move suitable installations to newer S7 controllers. Specialists assess compatibility and plan staged validation around production access and shutdown constraints.

TIA Portal development and S7 programming

Siemens automation engineers develop control software from machine specifications and review existing applications before changes. Bring in a specialist when a new machine needs programming or an established sequence needs revision.

TIA Portal developers: Write SCL and LAD code, structure reusable function blocks, and test sequence behavior with S7-PLCSIM where supported.
S7 PLC specialists: Program S7-1200 and S7-1500 controllers, define I/O mappings, and implement operating modes with explicit interlocks.

Scope can include code reviews and maintainable project documentation for subsequent engineering changes.

WinCC HMI development and commissioning

WinCC developers configure operator interfaces for SIMATIC panels and PC-based applications. Work covers alarm handling and diagnostic screens, with controls matched to the machine's operating modes. Specialists can revise existing projects or develop screens alongside new PLC logic.

During commissioning, Siemens automation engineers check field signals against electrical drawings and validate sequence transitions with site personnel. They investigate discrepancies between PLC behavior and HMI indications, then record tested changes. Commissioning scope depends on the installed hardware and access to the machine.

Industrial communications and system integration

Connect Siemens-controlled equipment to supervisory applications and other machines with engineers who can trace communication issues through the PLC project and network configuration.

PROFINET and PROFIBUS: Configure device exchanges and investigate faults involving device names, addressing, telegram configuration or network diagnostics.
OPC UA integration: Map controller data to SCADA or production applications, subject to CPU capabilities and licensing. Define access permissions and validate data exchange behavior.

Integration work includes agreeing interface contracts and testing connection-loss behavior before production use.

PLC support and STEP 7 migration

S7 support engineers investigate recurring machine stops and maintain applications as production requirements change. Online diagnostics and trace analysis help isolate sequence defects or unexpected field signals. Changes can include regression checks and documented rollback steps.

For legacy S7-300 and S7-400 installations, STEP 7 specialists assess source projects and hardware compatibility before proposing migration to TIA Portal or S7-1500. The assessment identifies instructions requiring revision and dependencies on discontinued equipment. Specialists can prepare converted code and support staged commissioning within agreed production windows.
