CAN Channels
CAN channels are sourced from a CAN connector on a CX23-R module.
Show common parameters
- Connector: A unique hardware identifier created by the system. To change the connector, remove the channel and re-add it using the correct connector.CAN connectors can be changed in the Change Device dialog.
- Name: The channel name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<', '>').
- Description: Enter an optional detailed description of the channel.
- Collect: Select the Collect checkbox to write the channel data to the SIE data file during a test run.
- Sample rate: Set the desired channel sample rate. If the sample rate changes, all dependent computed channels and DataModes are changed automatically.
- Measurand: Enter an optional measurement type.
- Range min and max: Specify the expected extreme values of the channel. May be any real number.
- Reading: Current value of the channel. Show the readings by selecting the desired channels and clicking
Live update.
- Decimals: Set the desired decimal places for the channel reading value.
- Units: Physical units of measurement for the channel.
- Data type: The format of the channel data output.
- Expiration time: Specify the time period in seconds that can elapse without data before data is considered stale and the output is set to the invalid value. The value may be any real number greater than zero.
- Invalid value: Specify the value to be set when the expiration time has elapsed without any data. The value may be any real number.
- Hardware interface: Value is CAN.
- Bit rate: Set the bit rate from the drop-down list of valid values. If the CAN bit rate is changed, all channels on the same port are changed to the same bit rate value automatically.
- Termination: Set the state of the internal termination resistor as true or false. If the termination state is changed, all channels on the same port are changed to the same state automatically.
- Request msg: Vehicle bus request message string.
- Request rate: Desired rate for active query requests. Only applicable if the request msg is supplied.
