User Communication
The user communication of the SmartAXIS enables you to control external devices such as computers, printers, and barcode
readers. For details on user communication, see "User Communication Instructions" on page 10-1.
Supported ports: Ethernet port and expansion communication ports

User Communication on RS232C
This example shows a system in which a SmartAXIS receives the data read by a barcode reader. The RS232C communication
cartridge (FT1A-PC1) is installed in a SmartAXIS expansion communication port, and then the barcode reader is connected to the
RS232C port.
Modbus Communication
The SmartAXIS is compliant with Modbus protocol and can be used as either a Modbus communication master or slave. When
used as a Modbus master, the SmartAXIS can monitor and modify the data of Modbus compliant devices, such as inverters and
temperature controllers, using Modbus communication.
For details on Modbus communication, see "Modbus Communication" on page 11-1.
Supported ports: Ethernet port and expansion communication ports

Modbus Communication on RS485
This example shows a system in which a SmartAXIS is communicating with a temperature controller and an inverter that support
Modbus RTU. The RS485 communication cartridge (FT1A-PC3) is installed in an expansion communication port on the SmartAXIS.
