8.8 Modbus Data Listing

(A) Modbus Coil List
The following tables list the primary coils for the inverter interface to the network. The table legend
is given below.
 Coil No. - The network register address offset for the coil. The coil data is a single bit (binary)
value.
 Item - The functional name of the coil
 R/W - The read-only (R) or read-write (R/W) access permitted to the inverter data
 Setting - The meaning of each of the states of the coils
