Commissioning scripts

Level 4 and Level 5
Commissioning Scripts from Your Site's Documents

Visum produces Level 4 functional performance tests and Level 5 integrated systems tests from a model of how the equipment is connected at the site, built from the site's sequence of operations and its single-line diagrams or piping and instrumentation diagrams, and a working model of each piece of equipment. Every step carries the expected result and its source, or is flagged for you to supply.

12 Tests, 53 Steps

  • Each step cited to a manual page or flagged
  • Every step carries the expected result
  • Where no document gives a value, the step is flagged for you to supply

What only Visum does

Scripts from the Equipment and Site Models

Visum reads the site's sequence of operations (SOO) first, for the expected response across equipment; the single-line diagram (SLD) or the piping and instrumentation diagram (P&ID), depending on the equipment, for which breaker or valve is operated and in what order; and the project specification for acceptance values. From these documents Visum builds a model of how the equipment is connected at that site, and combines it with a working model of each piece of equipment, such as a coolant distribution unit or a UPS, built from the manufacturer's manuals and drawings. The scripts come from the equipment and site models.

Flags a missing value instead of inventing one
Every acceptance value cites its source or is marked for you to supply.
Gives a correct start-up or switching order from the models
Not retyped from a procedure that may be out of date.
No LLM decides pass or fail
Every check runs as a fixed set of rules against the equipment and site models. The same procedure and the same models give the same result every time, so a pass cannot be fabricated.
Catches a second live feed
Visum checks every source that can energize a piece of equipment. If a second feed still reaches it after the isolation steps, Visum names that feed and its path.
Shows the downstream impact of a step
Before a step runs, see what else loses power or flow because of it.
The same models feed training, commissioning scripts and procedures
What technicians are trained on and what the check enforces never drift apart.
Who it is for

Operators, Manufacturers, Commissioning Firms and Maintenance Companies

Data center operators (hyperscalers, colos, enterprise), and the staff who run the equipment
Train your staff, and get commissioning scripts and procedures, built for your site's exact equipment and design.
What they buy: training for site staff; commissioning scripts and procedures for the equipment they install.
Equipment manufacturers (CDU, UPS, switchgear)
Your equipment, modelled from your documents, to train your field staff and your customers.
What they buy: a model of each equipment line, with training, commissioning scripts and procedures built on it.
Commissioning firms
Scripts with every expected result cited to the SOO, the drawings or the manual, and every missing value flagged.
What they buy: Level 4 and Level 5 commissioning scripts from the site's SOO, SLDs and P&IDs; training for their technicians.
Maintenance and service companies
Train technicians on the exact unit before they touch it.
What they buy: training for their technicians; procedures for the equipment they maintain.

Level 4 FPT and Level 5 IST scripts, every step cited or flagged.
