Create a data logging system from DPM-3 instruments

Point-to-Point Communications via RS-232	RS-485 multidrop communications

DPM-3-DLS data logging software turns a PC connected to up to 31 DPM-3 instruments into a powerful, low-cost data logging system.

Data can be displayed on the computer screen in the form of up to 64 simulated meters in 4 groups (or screens) of up to 16 meters each. The on-screen simulated meters can show the readings and alarm indications of selected actual meters, or show values other than those normally displayed by meters, such as peak value. They can also show calculated parameters, or weighted averages that combine data from multiple meters. For example, a virtual meter can display the sum of any number of meter by adding them togather. Available operands are multiply, divide, add, and subtract, with parentheses to allow complex expressions. The on-screen position and appearance of individual meters is user selectable to achieve meaningful groupings.

Data can be logged from selected meters into an ASCII file, which is easily imported into MS Excel for graphing and analysis. User settable parameters include the logging time interval in seconds, the separator character (normally a comma), and header data (with or without time and date). Data files can be password protected.

Hardware

Up to 31 DPM-3 meters can be connected to the PC in addressable multidrop fashion using a single RS-485 line. Each of these DPM-3 meters must be equipped with an RS-485 board. A single DPM-3 meter can be connected to a PC using an RS-232 line. That DPM-3 must be equipped with an RS-232 board.The computer must be PC compatible, operate under MS Windows 95 or higher, and have an available COM1 to COM9 serial port.

Software Installation

The DPM-3-DLS Data logging Software can be downloaded from this website at no charge.
Click here to download the file log4.zip. To install, double-click on the file and follow the on-screen directions.The free download version allows operation in the Demo Mode, which provides a good indication of the capabilities of the software. Connection to actual instruments requires a 12-digit activation code, which will be emailed by Transducer Techniques upon payment of $245. This code must be installed within 10 days of issue.
