3-7-6 Network Communications Settings
The following table lists parameters that configure the inverter's serial commu-
nications port. The settings affect how the inverter communication with a digi-
tal operator (such as 3G3AX-OP05), as well as a ModBus network (for
networked inverter applications). The settings cannot be edited via the net-
work, in order to ensure network reliability. Refer to Appendix B ModBus Net-
work Communications on page 261 for more information on controlling any
monitoring your inverter from a network.
