The software is based on microsoft windows operating system. It supports almost all versions of Windows, Windows 95 , Windows 98 , Windows ME , Windows NT , Windows 2000 Windows XP . This is a software which graphically controls, reads and writes a single instrument. The drivers of the various standard instruments are written as well as can be written on request. The instrument is read and controlled on the serial port. The serial port protocol can be customised protocol or standard MODBUS protocol. Again the drivers for the customised protocolcan be written on request.Due to this software, one can read one instrument or multiple instrumentsusing a standard PC. The read out data can be stored and graphically represented. The reading can be obtained on user settable periodic interval. One of the interesting feature of this product is user can initiallyset the pattern of the readings called 'profile'.Based on the periodic time interval, an instrument can be programmed as set by the profile. If there is any mismatch between profile parameters and actual parameter, alarm can be set.This software is extremely important to read single instrument or multiple instruments unattended over a long period of time. One can even programme a complete process instrumentation, process-wise, time-wise or both. This can be done completely unattended.
