Development, upgrade, downgrade, customization, integration and adaptation of software, including SCADA systems, HMIs and PLCs.

Software Development and Customization
How it works
The most common case is legacy migration: a platform the manufacturer discontinued, running on a line that cannot stop.
- 01
As-built survey
Documenting what is in the panel and mapping every I/O point. Plant documentation is usually out of date, and this is where the schedule blows out when the step is skipped.
- 02
Functional specification
The description of what the software will do is approved before a single line is written. It is what prevents rework and scope arguments later.
- 03
Convert or rewrite
An explicit decision between converting the code automatically and rewriting the logic on modern function blocks. The costs and the risks are different.
- 04
Development
Programming on a standardised library, instead of rebuilding every motor and valve from scratch. It is what makes the system maintainable for 15 or 20 years.
- 05
Simulation testing and FAT
The program is tested in a simulated environment before it reaches the shop floor.
- 06
Commissioning
Download to the machine in a shutdown window, point-by-point testing of real I/O and assisted start-up.
- 07
Documented handover
As-built logic and screens, versioned backup and a signed test protocol.

Frequently asked questions
Which systems do you work with?
SCADA systems, HMIs and PLCs: development, customisation, integration and adaptation.
Can an old system be updated?
It can. We upgrade, downgrade and adapt older platforms, integrating them into the process already running.
Do you integrate platforms from different manufacturers?
Yes. Integrating SCADA, HMI and PLC from different origins is part of the service.
