Designation of signals
Supervision and monitoringA few questions
Is your maintenance management system separated from the control system?
Are devices addressed in the same way in the maintenance and control systems?
Can the maintenance system be called up from outside the plant?
Any special functions that needs to be modelled?
Will the maintenance system give any alarms?
Of course you have!
