Version 0.9.13

Extended Modbus write configuration and optimized web interface

New features

• Modbus Holding Register targets now support selecting Automatic, FC06, or FC16 as the write function code.
• The selection is available for both Modbus RTU and Modbus TCP.
• Automatic mode uses FC06 for 16-bit values and FC16 for 32-bit values.
• XLSX import and export include the new setting.

Improvements

• Invalid combinations, such as FC06 with a 32-bit value, are prevented.
• The ineffective interval field has been removed from data targets.
• The web interface now uses less storage and network bandwidth through minification and compression.
• Existing configurations and older XLSX files remain compatible and automatically retain the previous behavior.

Notes

• Multi-Write must be enabled for the corresponding Modbus connection when using FC16.
• Coils continue to use FC05.
• 64-bit Modbus data types are not yet supported in this release.
