PLC Programming in Zurich

Program sections, safety technology, HMI and commissioning as defined work packages, to your standards

Prybisch Automation is an engineering office in Luxembourg for Siemens automation (TIA Portal, WinCC Unified, retrofits). For automation projects in and around Zurich we work under a contract for work for machine and plant builders, system integrators and infrastructure operators. Zurich is about 4 h 45 min from Stadtbredimus.

Sorting plant extension with safety technology

Recycling company, Luxembourg · engineering partner on behalf of a general contractor

Starting point
Existing drives with their own black-box control were to be replaced by fully integrated drives, and maintenance doors secured with interlocks. During the project, the planned F-CPU was discontinued.
Scope
Migration of the existing project from TIA Portal V19 to V21 with the successor F-CPU, drive integration with PROFIsafe/STO and IO-Link, four interlocks in the safety program with documentation against the standards. Commissioning during the planned shutdown.
Result
In operation and closed in July 2026. Fixed-price contract, additional work ordered as separate change orders.

Infrastructure control with WinCC Unified

Recycling company, Germany · engineering partner on behalf of a general contractor

Starting point
As part of expanding the low-voltage distribution and building services, lighting, heating, ventilation, fire-water and well supply were to run on one shared controller with an operator panel.
Scope
S7-1200 G2 in TIA Portal V21 with a Unified Basic panel, trends and long-term archive. Functional specification kept up to date, each stage tested in simulation before going on site.
Result
Ongoing (as of October 2026): lighting, temperature monitoring, ceiling fans and the fire-water section are in operation.

Automation engineering in Zurich

Machine and plant builders often see engineering work pile up: several projects going into commissioning at once, or an end customer ordering an extension. We take on defined packages such as program sections, safety technology or HMI. Programming and testing run remotely; for commissioning we come in planned blocks, for several weeks if needed.

For infrastructure and energy facilities, availability is what counts: distribution boards, pumps, heating and ventilation run on controllers that are extended over years. We run such projects with a continuously updated functional specification and test every stage in simulation before it goes onto the plant.

Your electrical partner or panel builder handles installation and wiring; we deliver software, HMI and commissioning. Existing plants we migrate to S7-1500: the S7-300 has been discontinued, with spare parts expected until around 2033, possibly for a shorter time according to Siemens.

Frequently asked questions

Do you work to our standards and libraries?

Yes. We adopt your block libraries, naming conventions and HMI templates and deliver program sections that fit straight into your project. Where no standard exists, we propose a structure and document it.

Do you program safety PLCs (F-CPU) to EN ISO 13849?

Yes. For a recycling plant in Luxembourg we implemented four guard-door interlocks in the safety program of an S7-1500F, with 1oo2 evaluation and evidence according to EN ISO 13849-1 and EN ISO 14119; the drives are connected via PROFIsafe with STO. The risk assessment remains with the machine manufacturer.

Do you handle commissioning at the end customer's site?

Yes, including assignments of several weeks, working with your team or the electrical contractor on site. More than 30 international commissioning projects – across most of Europe, in the USA, Tanzania, Malawi and Japan.

Do you also work on infrastructure and energy facilities?

Yes. A current example is the infrastructure control system of a recycling company in Germany: lighting, heating, ventilation and fire water on an S7-1200 G2 with a WinCC Unified panel, commissioned in stages.

How quickly can you be in Zurich?

Driving time from Stadtbredimus is about 4 h 45 min. Programming and testing happen remotely; planned on-site assignments are scheduled with some lead time, because they require a short advance notification. In a breakdown, we start via your remote access where available and arrange an on-site visit as soon as possible.

Who handles electrical installation and wiring?

Your electrical contractor or panel builder. We deliver software, HMI and commissioning and coordinate the interfaces with them.

How is the work billed?

For each defined engineering package you receive a fixed-price quote after the survey; commissioning and fault analysis are usually billed on a time-and-materials basis. We work under a contract for work, take care of the formalities and invoice in CHF, or in EUR on request.
