Check signed and unsigned values
Quickly compare raw values against their signed equivalent when a register appears to roll over or display incorrectly.
Built for real commissioning work
This tool is intended for engineers working with BMS integrations, Modbus meters, controllers, gateways and third-party equipment where register values do not always display as expected first time.
View hex and byte values
Useful when proving whether a device, gateway or BMS driver is reading the expected register data.
Useful for BMS engineers
Designed around practical Trend, Niagara, Synapsys and Modbus commissioning scenarios rather than generic programming theory.
Get the free Modbus tool
Enter your details and I’ll send you the free Modbus engineering tool. I’ll also send occasional BMS Logic Academy emails with engineering tools, training content, software consultancy information and relevant service offers. You can unsubscribe at any time.
The tool runs in your browser as a standalone HTML page, so you can save it locally and use it during commissioning.
