A process tower has to make phase, alarm and active axis clear at a glance.
The photos show a vertical structure with a touch HMI, alarms, panels and machine side. The page highlights the automation work where interface, physical signals and diagnostics have to help the operator read the process without wasting time.

Technical reading
Challenge, solution and operational result.
A case study isn't just a gallery: it links context, technical choice and operational result to show where D&D creates value.
01 · Challenge
Challenge
Coordinate vertical movements, gas/utilities, area safety and process states in a very compact layout.
02 · Solution
Solution
An HMI with a process mimic, axis states, active alarms and quick navigation between operating functions.
03 · Result
Result
Better machine readability, control of critical parameters and faster diagnosis in the field.
Visual case study
What you see, what you don't.
The visible part of the machine is only half the project. Explore the tower: behind every element there's the automation you don't see.
01 / 04
HMI interface
What you see
The mimic with active recipe, phases, parameters and safety states.
What you don't see
The logic that holds together the vertical process, axes and alarms and presents them in a single screen, readable at a glance.
02 / 04
Vertical structure
What you see
The vertical structure with the furnaces and the tower process.
What you don't see
The sequence that governs the process phases, with the enables between one phase and the next and the safety conditions.
03 / 04
Alarms
What you see
The indicator lights on the machine.
What you don't see
The diagnostics that link each alarm to its cause and station, so the intervention is targeted and quick instead of trial and error.
04 / 04
Machine-side controls
What you see
Pushbutton stations, controls and an emergency stop within reach.
What you don't see
The enables and interlocks that make every command safe and consistent with the real process state.

In depth
The process, step by step.
Fiber optic towers are a vertical process: structure, furnaces, axes and safety have to read as a single system. Here's how D&D made it manageable, step by step.
01 — Signal map
Signals first, in order.
We collected machine states, sensors, actuators, alarms and safety conditions into an orderly data base. It's the starting point: if the signals are clear and organised, PLC and HMI can work well and diagnostics become possible.
02 — HMI interface
The interface tells the process.
The HMI mimic shows active recipe, phases, parameters, axes and safety states. An interface built around the process — not the raw parameters — makes operation faster and less ambiguous for the operator.
03 — Machine side
The physical, consistent with the software.
Panels, pushbutton stations, indicator lights and local devices are integrated into the system. Physical feedback on the machine is consistent with the software diagnostics, so the operator trusts what they see and acts accordingly.
04 — Final check
Validated before production.
Before delivery we check sequences, thresholds and restart conditions with functional tests. The machine reaches production clearer for operator and maintenance, with behaviour already validated and less room for ambiguity.
