What we test on the virtual machine before a single cable is pulled
Sequences, abnormal cases, interlocks, alarms and operator graphics: the test campaign we run on the real configuration while the plant is still on paper.
Practical notes from our automation engineers
How we test, document and integrate control systems on real projects: virtual commissioning, DeltaV change control, functional specifications, Modbus packages and GMP validation.

An FHX file is plain text: compare two backups, review a modification before it is imported and keep a clean history for management of change and audits.
A good functional specification is the cheapest FAT you will ever do
SFC or GRAFCET, parameter list, alarm and interlock database, failure, abort and restart cases: how a precise functional analysis becomes the FAT script.
