HOW WE HANDLE CONTROLS SUPPORT

PROBLEM REVIEW

SYSTEM DIAGNOSIS

SYSTEM DIAGNOSIS

 Identify what failed, what equipment is affected, when the problem started, and what changed before the failure occurred. 

SYSTEM DIAGNOSIS

SYSTEM DIAGNOSIS

SYSTEM DIAGNOSIS

 Review alarms, controller status, HMI communications, I/O conditions, drawings, programs, network connections, and field-device feedback .

CORRECTION & TESTING

DOCUMENTATION & PREVENTION

DOCUMENTATION & PREVENTION

 Correct the fault, verify the affected sequence, test operating conditions, and confirm the equipment can return to service safely. 

DOCUMENTATION & PREVENTION

DOCUMENTATION & PREVENTION

DOCUMENTATION & PREVENTION

 Record the issue and correction, update available backups or drawings, and identify improvements that could prevent the problem from returning. 

Support Built Around Plant Operations

PLANNED AND RESPONSIVE SUPPORT

 Some controls problems require immediate diagnosis. Others are best corrected during a scheduled shutdown or planned upgrade. 

 ISI coordinates with operations, maintenance, engineering, IT, equipment vendors, and production teams to determine the safest and most practical path forward. Remote troubleshooting can be used when approved connectivity is available, while on-site support can address field wiring, equipment, instrumentation, and startup requirements.
