Scales & Balance Data Parser plugin for Data Loggers

Latest version: 5.0.1 build 1126. November 28, 2025.

The Scale Data Parser module for our data loggers (for example, Data Loggers) is designed to parse incoming data from various scales, balances, and weight indicators. It extracts only useful parameters from the data stream, such as weight, measurement units, stability status, and error codes. A complete list of supported scale and balance models is available on a separate documentation page.

The module correctly handles both continuous and single-shot data output, as well as different protocol formats from many manufacturers. The extracted values can be stored in a file, a database, passed to accounting systems, or SCADA. If necessary, Scale Data Parser can send a special command to the device to request data, either to trigger a new measurement or to force a read of the current weight on demand. This is useful in weighing systems where it is important to obtain data on a specific event (for example, button press, conveyor signal, or barcode scan).

Example

Example of typical incoming data from a scale:

S  +0012.34 kg<CR><LF>

After parsing, the module can provide structured values, for example:

DataSource = COM1
Timestamp = 2025-01-02 08:00:00
Weight = 12.34
Unit = "kg"
Stability = "S"
Error = ""

Key features

Parses data from a wide range of scales, balances, and weight indicators.
Extracts clean values such as weight, units, stability flags, and error codes.
Supports continuous and on-demand data modes from many vendor protocols.
Can send a command to the device to request a new measurement or current weight.
Outputs structured data suitable for writing to files, databases, SCADA, and business systems.

Summary

Scale Data Parser converts raw scale output into clear, structured values that are easy to log and integrate. It simplifies connection of weighing equipment to data collection systems and helps ensure reliable, event-driven, and 24x7 weight acquisition.
