Instrumentation Design Office

Instrumentation Design Office

Instrumentation Design Office (IDO) is software for creating and managing industrial instrumentation and control systems design data and documentation including instrument datasheets, loop diagrams, termination diagrams, hookup drawings, I/O lists, instrument index, cable schedules, Bill of Materials and other reports.

IDO consists of an integrated suite of software applications using advanced graphical user interfaces to a shared project or plant relational database. The user interface is intuitive and includes online help.

Much of the data is created through automated functions & design rules, picklists and use of catalog data and data importation. IDO essentially automates production of design documentation from the database ensuring superior design integrity and significant reduction in manual data entry.
