PROCESS CONTROL OPERATING SYSTEM FOR UNIX (PCOSUNIX)

PCOS is a packaged software system that interfaces with UNIX based operating systems (HP-UX, RTU, TC/IX) and analog/digital front-ends to provide a general purpose high-speed data acquisition capability. PCOS for UNIX is highly configurable at the user level, allowing modification of the user interface and extensions to both the real-time and data reduction capabilities.

PCOS for UNIX features include:

- A mouse-driven window system for a user-friendly operating environment, featuring:

Pull-down menus for PCOS function selection

Tables

Data-entry forms

- Real-time capabilities, including:

Data acquisition

Data logging

Engineering-unit conversion

Limit checking of converted data

Display of raw and converted data

User defined processes

- A database management system for efficient data storage, query, and retrieval.

- Automatic or manual calibration of A/D front-end hardware.

- Modules to convert acquired data to engineering units for various industry standard transducers including:

Thermocouple

Strain gage

RTD

- Modules to perform composite conversions such as:

Averages

Sums or differences

Products

Integrals

Running minimum or maximum

- Capability to incorporate user written programs, such as:

Conversion modules

Limit exception programs for operator control in an alarm condition

Display modules

Synchronous real-time routines

- Data reduction capabilities, including:

Replay of raw data on a 16 channel oscilloscope

Channel .vs. time plots in a user defined format

Channel .vs. channel plots in a user defined format

Multiple plots per page

Tabular presentation of data

Sets of tabular reports or plots generated automatically

Output directed to CRT or hard-copy device(s)
