Incorrect negative values in the runtime under specific circumstances for variables of the the DNP3_TG driver

Incorrect negative values in the runtime under specific circumstances for variables of the the DNP3_TG driver

Summary

Negative values for analog inputs and analog outputs with specific variations that are received from the outstation by the DNP3_TG driver, are not displayed correctly in the zenon runtime.

When using variations reprsenting single precision floating point or double precisision floating point values, negative values are displayed correctly in the zenon runtime. When using variations for 16 bit or 32 bit integers, negative values are not displayed correctly in the runtime.

Description

Negative values for analog inputs and analog outputs with specific variations that are received from the outstation by the DNP3_TG driver, are not displayed correctly in the zenon runtime.

When using variations reprsenting single precision floating point or double precisision floating point values, negative values are displayed correctly in the zenon runtime. When using variations for 16 bit or 32 bit integers, negative values are not displayed correctly in the runtime.

Solution

An issue has been addressed in the DNP3_TG driver where handling of negative values was not handled properly for all variations. Now negative values are displayed correctly for all variations
