Engineering services

Engineering for controland safety systems.

Beyond supply, our certified engineers design, program, commission and validate the systems your products go into.

Engineering services are coming soon.

For now, ask us about automation products, control panels built to order, machine guarding and technical support.

What we do

Our engineering services.

From a single machine-guarding upgrade to a full plant control system, the same engineers handle the risk assessment, the code and the commissioning.

Machine & functional safety

CMSE®CEFSISO 13849-1IEC 62061

Our core speciality. CMSE® and CEFS certified expertise takes your machine from risk assessment to validated, documented safety functions.

  • Risk assessment to ISO 12100
  • PL verification to ISO 13849-1 (SISTEMA) and SIL verification to IEC 62061
  • Safety distance calculations to ISO 13855 and ISO 13857
  • Safety PLCs (Siemens F-CPUs, Pilz PNOZmulti), PROFIsafe and safety relays
  • Interlocks, light curtains and E-stop circuits
  • Validation to ISO 13849-2 and technical file documentation

PLC & HMI programming

Structured, documented control software for new machines and upgrades.

  • Siemens S7-1200 / S7-1500 in TIA Portal
  • Rockwell Studio 5000, Pilz PAS4000 and Codesys
  • HMI and SCADA screens in WinCC and PASvisu

Commissioning

Factory and site acceptance tests (FAT/SAT), loop checks and handover.

Networking

PROFINET, EtherNet/IP, Modbus TCP, OPC UA, VLANs and industrial wireless.

Industrial IoT & data

Collect machine data from your PLCs and show it where people can act on it.

  • Real-time data acquisition from PLCs
  • Edge devices such as Revolution Pi
  • Machine performance and downtime dashboards

Panel design

Schematics, layouts and BOMs in EPLAN P8, AutoCAD and AutoCAD Electrical, designed to IEC 60204-1.

Retrofits

New controls and safety for existing machines, even without the original source files.

Documentation & training

Clear documentation and training, so your team can maintain the system after handover.

  • Functional design specifications (FDS) and sequences of operation
  • Safety technical files and validation reports
  • Technical workshops for engineering teams
  • Operator, maintenance and PLC training
Sales and supply

Need the parts too?

PLCs, safety components, drives, sensors, networking and panel parts, chosen by the engineers who will commission them.

Our approach

One team across the
whole project lifecycle.

No hand-offs between separate consultants, programmers and commissioning teams. The engineers who assess the risk also write and commission the code, and safety validation is reviewed independently.

01

Assess

Site survey, risk assessment and requirements.

02

Design

Control architecture, safety functions, FDS and drawings.

03

Build

PLC, HMI and safety code, tested offline before site.

04

Validate

FAT, SAT, loop checks and safety validation on site.

05

Support

Training, handover files and ongoing support.

Why Parshvalogic

Experience that counts when projects get difficult.

Legacy machines, mixed vendors and tight shutdown windows are situations we have handled on operating sites.

/01

Legacy systems without source files

We can trace an existing control system, rebuild the program on a current platform and roll it out across identical machines.

/02

Mixed-vendor integration

We connect safety PLCs, standard PLCs and SCADA from different vendors over PROFINET, EtherNet/IP, Modbus TCP and OPC UA.

/03

Shutdown-window commissioning

We plan on-site testing and fault finding around your production shutdown, with a clear punch list for handover.

/04

Documented safety

Safety functions come with SISTEMA calculations, validation records and input for your technical file.
