Flexible DIO Configuration in Ethos

• Flexible DIO configuration allows users to customize digital input and output signals according to their requirements.
• This feature also applies to analog signals, but will be covered later.

DIO Configuration Section

• To access the DIO configuration section, users go to the settings on the Ethos home screen.
• The DIO configuration section displays a list of available signals on the unit, which can be extensive depending on the system's complexity.

Understanding the DIO Configuration Table

• The table has five columns: Function, Signal Type, Configuration, Assembly, and Channel.
• The Function column indicates whether a signal is an input (marked with "I") or an output (marked with "O").
• The Signal Type column shows whether signals come from/go to the DIO card or are part of the Modbus protocol.
• The Configuration column specifies whether an electric signal is high or low active.
• The Assembly and Channel columns enable users to modify the channel or assembly associated with a signal without disconnecting/reconnecting wires.

Customizing Signals

• Some signals are pre-configured based on the system's ordered functions.
• Other signals, such as binary inputs and outputs, are freely available for customization.
• Users can rename and configure these free signals as needed.

Ethos AIO Configuration

• Ethos AIO configuration allows for flexible configuration of analog signals and can be accessed from the home screen settings.

Analog Signal Configuration

Common Mistakes in Handling Etheros

Encryption

• Enable SSL/TLS encryption during commissioning or in the communications tab to ensure secure access
• Always use https in the address line to access the system after encryption is enabled

Dio Connection Cable

• Securely connect the purple cable between the CPU and Dio modules to prevent error stage and LED changes
• Power down the system, reconnect and tighten the cable, and then power up again to resolve connection issues

Ethernet Connection

• Use eth 2.1 port on the CPU module for communication to avoid issues
• Verify the correct port to ensure proper communication

Dio Module Power Supply

• Connect and power up the Dio module's power supply unit to ensure proper operation
• Check the power supply unit's LED for indication of proper operation

Event Confirmation

• Acknowledge or confirm events as required on the event screen to prevent system issues
• Regularly check the event screen for events requiring acknowledgment or confirmation

Visualization Issues

• Clear browser cache to resolve strange visualization issues and prevent future occurrences
• Regularly clearing cache can prevent visualization issues from arising

Configuration and Expansion

• Install cards card by card or slot by slot as per the electrical diagram when expanding the system
• Avoid mixing up slots or rotating cards to prevent startup errors during system expansion

Serialization and Unit Identification

• Verify the serial number of the unit matches the software being imported to avoid error messages
• Check the serial number before importing software to ensure compatibility

Canvas Communication Cards

• Use connectors with built-in resistors for cable termination in some units to prevent communication issues
• Ensure correct positioning of connectors to prevent communication issues

IP Address Configuration

• Change the local IP address of the computer or ethernet adapter to match the unit's IP range (192.168.165.x) for proper access
• Set the IP address to access the unit properly and avoid connection issues
