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
- The configuration lists available functions, including inputs and outputs, with their respective units.
- Supported signal types include:

- Adding a correction factor and correction offset to fine-tune the signal
General Purpose Analog Signals
- General Purpose Analog In (GPAI) and General Purpose Analog Out (GPAO) signals can be configured.
- GPAI and GPAO signals can be linked to a free channel and configured with a specific unit from a long list of common physical units (e.g., bar, psi for pressure).
- Configuration options include selecting a multiplier (e.g., milli, kilo, mega) and decimal places.
Event Screen
- Displays all pending events on Ethos, categorized into three types: alarms (red), warnings (yellow), and information (gray).
- Each event has a unique event number and a full timestamp.
- Allows users to change the status and designation of events, including changing names and colors.
Event Log
- A historic list of all events that have occurred, organized by general function (e.g., drive, cabinet, cooling, etc.).
Filtering and Exporting Event Log

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
