Electrical / I&C-engineering

Consulting service

Based on our long lasting, comprehensive experiences as All-in-One supplier for the automation technology of our flue gas treatment plants, we will be pleased to provide advice, develop ideas and show solutions. In this connection energy saving, safe operation and high availability of your plant are having top priority. On this basis we will prepare a concept for you suitable for the realisation of your control application.

When preparing the concept, the technologies of the following system suppliers are preferred:

  • Siemens (Protection, Switching, SPS S7-300/400, PCS7, Frequency converters,...)
  • ABB (Protection, Switching, Frequency converters)
  • Möller (Protection, Switching)

Special solutions can also be realised.

Engineering (Hardware)

Based on consumer and measuring points list and with the help of up-to-date planning tools we are generating the detail plans for the production of your tailor-made electrotechnical plant. Our used planning tools are ELCAD and EPLAN as well as AUTOCAD. All economic aspects, relevant laws as well as currently valid standards and guidelines are taken into consideration. As a result of this, the following documents will be issued:

  • Circuit plans
  • Terminal plans
  • Cable lists
  • Parts lists
  • I/O lists
  • Control room- / control panel layout
  • Hook-Ups
  • Planning of assembly and documentation
  • Lighting plan
  • Functional description
  • Safety concept
Engineering (Software)

Based on the results of hardware planning, we will prepare for you the adequate software application. With regard to I&C applications, we are using the Siemens planning tool PCS7. In case of large-scale plants we are acting as a part of a multi project and conform to the customer-provided conditions (libraries, typicals, concept of operation, ...). Of course we also supply turn-key PCS7 control centre solutions.

Beside the I&C requirements, we are supplying the complete software engineering for Siemens control systems of series S7-300/400. In this connection we are using self-developed software libraries, templates and HMI-solutions. We attach importance on a max. availability of your plant and an optimal, intuitive operability. Even in case of questions regarding the automation with Allen Bradley or Schneider we are the competent contact.

We are at your disposal even after commissioning. With regard to supporting diagnostics and measures for optimisation, we can offer the possibility of remote maintenance (56k, DSL, LAN).

In case of complex plants and customer-provided software design, we will prepare function plans with the engineering tool LogiDoc (Logi.Cals) accord. to power plant standard VGB R170C.

As a result of the software engineering we will provide:

  • PLC project (incl. source files)
  • HMI project
  • Functional description (PDF, Word)
  • Function plans (PDF)

The projected electrotechnical plants will be manufactured and tested in our in-house control panel production. The systems in questions are partially type-approved control systems. Special solutions such as medium voltage control systems, type-approved control systems or MCC with plug-in systems will be provided by long lasting partners.

Factory Acceptance Test

Regarding the verification of planned process-related functions of flue gas treatment plant, we are offering the possibility of a FAT (Factory Acceptance Test) in our company. Modern simulation tools such as SIMIT (Siemens) are available for this. Furthermore, the simulation of plant automation can contribute to a considerable reduction of cold commissioning period.
