RS485 Communication
Command settings for assigning master inverters
Set-up destinations
M: Perform the setting to inverters having station
numbers designated in [CF-20] and [CF-21] (=
master inverters).
14.5.3
EzCOM Operation
(1) A master inverter transmits data to slave
inverters according to the settings made to the
master inverter.
(2) The controlling inverter transmits a master
switching command, and then a master inverter
is switched.
(3) The next master inverter transmits data to slave
inverters as described in (1).
(4) Processes of (2) and (3) will follow, and the
whole processes will be repeated likewise.
*3) As for the transmission destination register and
the transmission source register, specify the
register address obtained by subtracting one
from the register No. For information on register
address, please contact the sales officer of our
company shown on the back cover.
• Entire communication data is transmitted to all
stations because EzCOM communication is
performed by broadcast communication. As a
result, a slave not designated as transmission
destinations on the master side receives data once,
but internally discards the data which is not
addressed to it.
