Network Communication Settings
The following table lists parameters that configure the inverter’s serial communications
port. The settings affect how the inverter communicates with a digital operator (such as
SRW–0EX), as well as a ModBus network (for networked inverter applications). The
settings cannot be edited via the network, in order to ensure network reliability. Refer to
“
ModBus Network Communications” on page B–1 for more information on controlling
and monitoring your inverter from a network.
