The inverter is to be connected to the Serial Communications Unit (SCU), Serial Communication Board (SCB),
or a serial port on the CP Series CPU unit.
This FB initialize parameters for serial ports to work with 3G3MV series inverter which have communication
parameters set to factory setting.
If other setting for more performance is needed, use FB
_SCX604SetPortGateway according to Function description below.
■ Inverter Settings
• Slave address(n153/H5-01)= 1 to 31
A unique setting required for all nodes on same MODBUS line.
■ PLC Parameters
• See users manual for RS422/485 wire.
• Serial communication unit or board must have serial gateway function to MODBUS line.
■ Shared Resources
• No Special resource to specify

variables
A EN input would set the specified Serial port for 3G3MV inverter communication parameter on factory setting.
and then restarts Serial Communication unit or board to run with the parameter.
For other communication setting (Non-parity or faster baud-rate=19200) , use _SCX604SetPortGateway.
■ Communication Parameters
• Mode=9:Serial Gateway
• 3G3MV Factory setting.
¾
Data=8bit
¾
Stop=1bit
¾
Parity (n155/H5-03)=Even (disagree with 3G3RV, CIMR (-F7Z/ -E7Z/ -L7Z/ -G7) Factory setting)
¾
Baud (n154/H5-02)=9600 bit/s
¾
Delay =0 (default)
.
• The FB does not check for restart have finished.
• An upwardly differentiated signal or a 1 cycle on signal should be used. otherwise, the Serial Communication
unit does not start because of the restart bit stay ON.
• When any input variable is out of range, ENO will be turned OFF and the FB will not be executed.
• Always use an upwardly differentiated version of input to EN.
