5.5 Supported Modbus Functions
Table T5.1 Supported Modbus Functions
Table T5.1 above lists all of the Modbus functions supported by an SV160E2. AMCI supports all of these
functions so that you can control the unit as you see fit. However, if you are looking for the easiest way to
interface with your unit, then you only need to use the
Read/Write Registers
function, which is function code
23.
Each SV160E2 buffers the data that is sent to it over the network. If you use the
Read/Write
Registers
function to write configuration data to the unit, then the data read with that command
will not contain the response to the new configuration data. The response to the new data will
be sent with the next data read.
