ApplicationData Logging, Show Temperature Graph
Software Version16

In the era of computerization, the user friendliness and the usability of the computer is very common aspect in the industry. Computers are widely used for the majority of the industrial applications. In order to use the benefit and power of the pc, libratherm offers standard, customized and dedicated computer programs or the software which runs on the window based operating platform in connection with the various libratherm make temperature and process controllers, programmers and data loggers to monitor the online process behaviour.

Though, various industrial well known scada software package also do the job of pc interfacing, we still prefer to offer our own dedicated das software for the reason of our ability of customization, low cost and modification of the required hardware to meet the end users applications - when compared to the scada package. The various microprocessor and microcontroller based instruments are interfaced with the pc on rs232 serial port or rs485 bus having modbus rtu or ascii protocol.

Brief description of some of the software is described below:

Datalog 16 software – Designed to interface with our datalog-16, monitors and displays the process value of all 16 channels – which are updated every 1 second. Facility to view the real time line graph of the process values, where user can select or deselect the channel, can zoom in or zoom out with auto scaling of x or y co-ordinates, the data base is created in back ground which can also be seen in the tabular format with real time and date. The records can be easily searched by date, time or by the customized and user selectable field. The software can be customized to group the monitoring of single or multiples systems with suitable identifications. Other software versions such as htlogger software to interface with humidity and temperature logger is also available.
