Process Control System Maintenance Automation
A combination of hardware, software and services used to assess the heal of plant assets by monitoring asset condition periodically or in real-time to identify potential problems before they affect the process or lead to a catastrophic failure.

Beneficial Concepts and Features of PCSMA
- 24 -
Beneficial Concepts of PCSMA
1. Minimize Risks & Cost (lead-time) for commissioning & start-up work
Centralized Plug & Play remote device connection check
Centralized remote setting of field device parameters
Quick online diagnosis
Standardized approach for multi-vendor devices
2. Minimize the risk of unnecessary site trips By monitoring device healthiness thru diagnostics
3. Minimize scheduled maintenance downtime Optimize maintenance work by advanced device diagnostics
4. Generate collaboration between Operation and Maintenance
Maintenance work to assure Reliability, but not repair work after breakdown.
Shift maintenance paradigm from event-driven to scheduled work
Maintenance to contribute better operation availability.
- 25 -
1. Real time Plant Asset Management Environment – Cyclic device patrol of device health condition check – Maintenance alarm to maintenance personnel – User-friendly device configuration tools (EDDL and FDT/DTM base)
2. Full integration with DCS and SIS – Device alarm message equalization – Time synchronization – Device diagnosis alarm to be shown on the DCS HMI
3. Wide Openness
– Remote alarm & event monitoring, analysis and reporting
– Integration: Host diagnostics server interface of both field devices and machinery units
– Open interface: CommDTM/DeviceDTM are available
Safer plant operation – PST Scheduler to extend the available time of SIL3 safety loop without
process shutdown

Maintenance Related Functions
Schedule – Records maintenance schedule
Memo – Records maintenance memorandum
Parts – Records necessary parts for devices
Doc – Records necessary documents for maintenance such
as instruction manual
Tool – Setup the necessary tools for maintenance
Plug-in – Setup to ranch necessary tools for devices configuration
Cal. Data – Records calibration data for devices

Maintenance Mark and Operation Mark Synchronization
PRM is able to electronically assign “Maintenance Mark” to each device by online. Users can assign this mark when they adjust or maintain the field devices. Once assigning it, users can give the restriction to handle with field devices management and what they has been in the status of adjustment and maintenance. When the Maintenance Mark is set on PRM, Operation Mark to prohibit the operation is automatically set on the HIS faceplate.

Summary
Process Control Systems architectures nowadays can integrate nodes for supporting diagnosis and maintenance functions
System performance monitoring and maintenance operations can be done both by local and remote workstations – Process Trends, Process/System alarms can be viewed
by remote through redundant connected SQL servers
– Field instruments and devices status can be checked and updated even by remote
