Why Wago is a strategic choice for many projects
Wago is one of the leading European manufacturers in industrial automation and building automation. Its catalogue combines the modular 750/753 I/O system, the PFC100 and PFC200 controllers, edge controllers with native cloud connectivity, and an ecosystem of spring-cage terminal blocks and connectors that has become a de-facto standard in many electrical cabinets. For us, integrating Wago is not about following a trend: it is about choosing an open, multi-protocol platform built on Codesys, which makes it a very versatile component within heterogeneous projects.
The PFC + Codesys combination delivers three qualities that are particularly valuable in industry and building management: vendor independence at the software level (Codesys is a portable IEC 61131-3 standard), native support for fieldbuses and modern protocols (Modbus TCP/RTU, Profibus, CANopen, EtherCAT, BACnet, KNX IP, MQTT, OPC UA), and a very competitive cost per point when the 750 system is correctly sized.
What we do as Wago integrators
We work with the Wago range across full industrial automation and BMS projects, covering the entire project lifecycle:
- Control engineering: architecture definition, sizing of the 750 system, controller selection (PFC100/PFC200/Edge) and design of the communication networks.
- PLC programming: logic development in Codesys and e!COCKPIT, applying modular structure, reusable libraries and proven patterns (alarm management, recipes, operating modes).
- Visualisation: HMI through WebVisu (served from the PLC itself) or external SCADA systems where the project scope justifies it.
- Communications: Modbus TCP/RTU, BACnet IP, KNX IP, MQTT and OPC UA integration — both as client and server — to connect Wago controllers with third-party equipment, BMS or IIoT platforms.
- Edge & IIoT: use of Wago's edge controllers to pre-process data at the plant and forward it to cloud platforms or OPC UA servers without the need for additional industrial PCs.
- Commissioning and documentation: FAT/SAT testing, electrical drawings in Eplan, operator manual and full programme backup delivered to the client.
Technical scope: what we cover
| Wago product | Typical applications |
|---|---|
| PFC100 | Compact PLC for machines and sub-processes: distributed control, protocol gateways, technical-room automation. |
| PFC200 | High-end PLC with dual Ethernet, extended I/O capacity and multi-protocol support for demanding processes and BMS. |
| 750/753 system | Fine-grained modular I/O: digital, analogue, counters, serial communications and specialty modules (RTD, thermocouple, IO-Link). |
| Edge Controller | On-plant control + Linux + Docker containers: ideal for IIoT solutions, data aggregation and local dashboards. |
| I/O System Field | IP67 I/O directly on the machine, removing intermediate cabinets and reducing cabling. |
Sectors where we apply Wago
The platform's versatility lets us use it across very different sectors. Some real examples where Wago tends to fit particularly well:
- Building automation and BMS: HVAC, lighting and energy management with native BACnet IP and KNX IP.
- Telemetry and utilities: remote stations with 4G/Modbus/OPC UA communications, ideal for WWTPs, drinking-water plants and silos.
- Process machinery: control of discrete and continuous-process machines with distributed I/O in remote enclosures.
- Ceramic, food and chemical industry: gateways between heterogeneous PLCs and SCADA or MES systems, leveraging the multi-protocol support of the PFC.
Why a specialised integrator makes the difference
Wago is a powerful platform, but its real potential depends on how it is programmed. We have audited installations where the hardware was correct but the code was a single monolithic POU that was impossible to maintain; and projects where the 750 system was over-sized — and others where it was under-sized from day one. A good Wago integrator must have proven experience with Codesys oriented to IEC 61131-3 (structured POUs, reusable FBs, version control), not just with the tool as a code editor.
At Bluemation we treat Wago projects like any other serious industrial project: with up-front design, a justified architecture, maintainable code and deliverables that let the client keep operating even if they switch supplier. We do not sell hardware: we sell control engineering, which means we recommend Wago when it is the best technical and economic option, not by default.
How we work with you
- Initial technical analysis at no commitment: review of the installation, process requirements and compatibility with the client's installed base.
- Architecture proposal and quotation: with a breakdown of engineering hours, Wago hardware list and phased delivery plan.
- Office-based development: programming, simulation and internal testing before stepping onto the plant.
- On-site commissioning: FAT, SAT, training for the operations team and full documentation handover.
- Post-delivery support: optional maintenance contract with SLA, secure remote access and updates.
If you are evaluating Wago for a new project, a migration from another brand, or an extension of an existing installation, share the details with us. We provide a no-obligation technical analysis and we tell you honestly whether Wago is the best option for your case or whether another alternative makes more sense.
