Different slaves on the same network should
set different local addresses;
0 is the broadcast address, all slave inverters
can be identified
0:1200 bps; 1:2400 bps

1~20msThe delay time of the local to answer
the master
0.0s(disabled)~60.0s(works for master-slave
system) When this function code effective,if
slave do not receive data from master
overtime,it will trip as Er.485
Number of
frames
received by
Modbus
Each time a frame is received, this value is
incremented by 1,0 to 65535 cycles.
Number of
frames that
Modbus has
sent
Each time a frame is sent, this value is
incremented by 1,0 to 65,536 cycles.
Number of
error frames
received by
Modbus
Each time an CRC error frame is received,
this value is incremented by 1,0 to 65535
cycles; it can be used to judge the degree of
communication interference.
