Functions
14.5 Modbus TCP communication
Description of function
A Modbus TCP register comprises 16 bits. The values of the converter display parameters (r
parameters) cannot always be represented with 16 bits. In these particular cases, the maximum
value that can be represented is displayed.
• Unsigned: 65535
• Signed min: -32768
