Mosa Industrial Switch Parameters

Moxa industrial switches, such as the EDS-518A series, can be configured via serial console, Telnet, or web browser, with key parameters including COM port, baud rate, data bits, parity, stop bits, and terminal type, while Modbus TCP can be enabled for SCADA integration.

Accessing the Switch

Moxa switches can be accessed in three main ways:

• Serial Console: Connect a short serial cable from the switch to a PC's COM port. This is useful if the switch's IP address is unknown. Configure the console with 115200 baud rate, 8 data bits, no parity, 1 stop bit, and VT100 terminal type ( ).
• Telnet Console: Allows remote command-line access over the network. Note that serial console and Telnet cannot be used simultaneously ( ).
• Web Browser: Provides a graphical interface for configuration. It can be used simultaneously with either serial console or Telnet ( ).

Serial Console Configuration

1. Open the Communication Parameter page in the Moxa utility.
2. Select the appropriate COM port.
3. Set Baud Rate to 115200, Data Bits to 8, Parity to None, and Stop Bits to 1.
4. Under the Terminal tab, select VT100 for terminal type and click OK ( ).

Modbus TCP Settings

Moxa switches support Modbus TCP/IP for SCADA system integration:

• Enable Modbus TCP: Check the box in the configuration interface and click Activate. It is enabled by default ( ).
• Data Access: Supports Function Code 4 with 16-bit (2-word) read-only data.
• Address Mapping: MODBUS addresses start at 30001. For example, offset 0x0000 corresponds to 30001, and 0x0010 corresponds to 30017. All data is in hexadecimal format and can be interpreted using an ASCII table ( ).
• Disable Modbus TCP: Uncheck the enable box and click Apply ( ).

Recommended Software and Accessories

• EDS-SNMP OPC Server Pro for network monitoring.
• DIN-Rail 24 VDC Power Supply Series (DR-4524, DR-75-24, DR-120-24) for reliable industrial operation ( ).

Additional Notes

• Moxa switches are designed for rugged industrial environments with high port density and Gigabit-speed operation ( ).
• Always ensure firmware and manuals are up to date to avoid configuration errors ( ). By following these settings, Moxa industrial switches can be properly configured for both local and remote management, as well as integrated into SCADA systems for real-time monitoring.
