Control signal
This page documents the [control] configuration section.
The CL2000 logging state (enabled/disabled) can be changed run-time using the control-signal.
Note
The initial (power-on) logging state is set using loggingEnb (see loggingEnb)
Default
[control]
controlEnb = false ; Enable control signal
extendedID = true ; Use extended 29 bit message ID (2.0B)
msgID = 00435354 ; CAN message ID of control signal (HEX)

State |
The length of payload must be 1 byte. The value of the State byte sets the state of logging:
0x00: Logging disabled0x01: Logging enabled
Examples
Example 1: The initial logging state (loggingEnb) is true. Nine messages (ID 1, 2, …, 9) are transmitted on the bus. After the message with ID 3, the control signal disables logging. Logging is enabled before the message with ID 7.
Below table shows the resulting log entries recorded by the device.
