6.3.3 

Handling the checksum when working with the SFE tool 

As standard, the SFE tool attaches the checksum Modbus CRC16 to every command and checks the 

response of the SFE unit for correctness using the checksum. 
 

Important note! 

 

The checksum which is attached to the command by the SFE tool is not displayed in the SFE 

tool console. In addition, the checksum of the response attached by the SFE unit is also not 

shown in the console.
