What is PLC Programming?

Automate your production with PLC programming

A PLC (Programmable Logic Controller) is the brain of any industrial automation system. PLC programming is about developing the control software that drives machines, production lines and industrial processes, automating repetitive tasks, improving precision and reducing human error.

At Bluemation we are specialists in PLC programming in Spain with more than 10 years of experience in sectors such as energy, logistics, aerospace and manufacturing. We work with the leading manufacturers on the market: Siemens, Beckhoff, Rockwell (Allen-Bradley), Schneider Electric and Codesys.

Every PLC programming project we deliver is fully tailored to the customer's specific needs: from automating a single machine to integrating an entire production line.

PLC Platforms

Our Services

Everything our PLC programming covers

Custom PLC software development

We programme control logic precisely tailored to your production process: sequences, timers, counters, motion control, communications and more.

HMI and SCADA programming

We design intuitive operator interfaces (HMI) and SCADA systems for real-time visualisation and control of your plant or machine.

Commissioning and start-up

We travel to your facilities for commissioning, testing and tuning of the PLC automation system on site.

PLC migration and modernisation

We upgrade obsolete PLC systems to modern platforms without halting production. We migrate legacy programs to modern PLCs.

Communications integration

We configure industrial networks: Profinet, Profibus, EtherNet/IP, Modbus, OPC-UA and communication protocols between PLCs, SCADA and ERP systems.

Technical support and maintenance

We provide ongoing technical support, fault resolution and preventive maintenance of PLC systems to minimise production downtime.

Frequently Asked Questions

What is PLC programming and what is it for?

A PLC (Programmable Logic Controller) is the brain of industrial automation systems. We programme it to execute control sequences, manage sensor and actuator I/O, communicate with SCADAs and HMIs, and ensure safe, autonomous operation of industrial machines and processes.

Which PLC brands do you programme?

We programme Siemens (S7-1200, S7-1500, S7-300 with TIA Portal and STEP 7), Beckhoff TwinCAT 2 and 3, Rockwell ControlLogix and CompactLogix (Studio 5000/RSLogix 5000), Schneider Modicon M340/M580 and any platform that runs Codesys 2 or 3.

How long does it take to programme a PLC for my project?

It depends on process complexity and the number of I/O. A simple project (20-40 I/O, linear process) can be ready in 2-3 weeks. Complex projects with multiple operating modes, functional safety or SCADA integration may take 2-4 months. We provide a detailed estimate after the functional analysis.

Can you programme an existing PLC without documentation?

Yes. We audit installations with existing programs: we study the code, build functional documentation from scratch and propose improvements or migrations. We always take a full backup before any intervention on a system in production.

What is the difference between PLC and DCS?

A PLC is optimised for sequence logic, discrete control and fast scan cycles. A DCS (Distributed Control System) is designed for continuous processes with many regulation loops and high availability. For most modern industrial applications, high-end PLCs (Siemens S7-1500, Beckhoff TwinCAT) cover both functions.

Do you migrate obsolete PLCs?

Yes. We migrate S7-300/S7-400 systems to S7-1500, legacy Siemens S5 PLCs to TIA Portal, and other discontinued platforms. The process includes analysis of the existing program, validated conversion, FAT/SAT testing and full documentation of the new system.
