The Component Isolation Support (CIS) system is a system which supports the planning and preparation of plant maintenance.  
When planning a work order the component clearance points and procedures must be identified and written as work instructions. This planning may require a lot of effort, planning experience, reviews and time.
The CIS system supports this task by using graphic displays of facility piping and instrument diagram (P&ID) and its component database to automatically identify clearances.  In addition, the CIS system can automatically create various isolation check sheets (tag lists) and the components isolation tags.

Key Features

The CIS system can identify the relationship between flow lines and valves, pumps and other devices from P&IDs created with Mitsubishi Electric Corporation’s  CAD software “R-schemer”. Isolation points for component clearances can be efficiently processed using the built-in ​functions of the CIS system.


  • Create Tag Out Lists for Work Orders from a P&ID
    • Work planners can verify isolation points on a P&ID and integrate isolation points for Work Orders.
    • Historical isolation data can be reused to save time.
    • Component Isolation Tags (attached to isolated components) can be created and printed out from the information in the Work Order Sheet.


  • Create Check Sheets for Work Orders
    • Various types of work check sheets can be developed depending on required work such as the Isolation Check Sheet (at regular inspection), the Isolation Area Boundary Check Sheet (at regular inspection) and the Isolation Check Sheet (at shutdown).
  • Manage Data
    • The CIS system manages and maintains the plant component information used in the system database like valves, pumps, ,motors, electric power supplies, switches or controllers. This information can be easily referenced from P&IDs with a popup window.
  • Options
    • The CIS system also provides component specification lists and inspection data lists which include inspection criteria, measured values and evaluation results. In addition, the inspection records for each piece of component can be displayed as trend charts.
