5.5.4 Protocols > Modbus
The protocol parameters configure the protocols that run over the serial interface or the
Ethernet interface (HART or MODBUS). When using the serial interface, only one protocol
can be active at a time (either HART or MODBUS), depending on the value of the serial
interface parameter Protocol Selection (see chapter 5.5.1). When using the Ethernet
interface, there is no need to select a protocol. Both protocols run parallel using different
port numbers.
