The maximum data length of a Modbus transmission is 256 bytes. This results in a user
data length of 253 bytes.
The number of data bits and stop bits is dened in the Modbus denition. Baud rates of
less than 4800baud are possible by denition, but not implemented at present. The inter-
face parameters can only be congured on the device (not via bus).
14.4 Device settings
The settings are read with the 0x04 command (read input registers) as shown in Table 1.
Writing is not possible at present.
