Affected products:
ESP-HMI1-P Version 1.3
Implications of the problem:
Rounding errors occur in the last decimal places (> 7) of a displayed variable.
When does the problem occur:
The problem occurs in digit fields with a floating point display format and more than 7 visible digits.
The following illustrates a problem with 10 visible digits:
- Variable content: 1.000000000 (correct value)
- Display on the terminal: 1.000000040 (actual value)
The following illustrates that no problem occurs with 7 visible digits:
- Variable content: 1.234567 (correct value)
- Display on the terminal: 1.234567 (actual value)
- also OK: 12.34567; 1234.567, 123456.7 or 0.1234567
Diagnostic options:
Compare the variable content on the transmitter side with the display on the terminal.
Short-term measures/recommendations:
Do not use more than 7 characters in the floating point display format.
