RIOW REMOTE MODULES. (CANOPEN PROTOCOL).
5.5.3 Meaning of the LED's.
While staring the module up, the LED's indicate the stage the node is in and its status.
When a module is in configuration mode (dipswitch value equal to ·0·), the LED's indicate
the speed selected at the module. See "5.5.2 Node configuration." on page 77.
LED's STOP, RUN, TX overflow and RX overflow.
The top four LED's of the module (STOP, RUN, TX overflow and RX overflow) indicate the
status of the node and of the communication through the CAN bus.
Led I/O.
Three-colored LED (orange/red/green) that indicates the bus status and the errors found.
Node status. Meaning.
Initializing stage After starting up or after a reset, the module goes into the initializing
stage to run an autotest. During the initializing stage, the I/O LED
blinks orange until it changes to red.
• If the module is properly initialized, it changes to the pre-
operative stage, the I/O LED changes to green and the RUN
LED blinks.
• If the module detects any problem in the initializing stage, it
changes to the stop stage, the I/O LED blinks red and the STOP
LED turns on. The blinking rate of the I/O LED indicates the
detected error.
Pre-operative stage. In this stage, the module configures the bus.
During the pre-operative stage, the I/O LED turns green and the
RUN LED blinks.
Operative stage. In this stage, the module is ready to work.
In the operative stage, the I/O and RUN LED's turn green.
Stop stage. This stage indicates an error at the node.
The STOP LED turns on in the stop stage.
STOP RUN Meaning.
OFF OFF Module turned off or in initializing stage.
OFF Blinking slow Module in pre-operative stage.
OFF ON Module in operative stage.
ON OFF Module in stop stage. Node configuration error or bus error.
OFF Blinking fast Module in pre-operative stage. Module error.
Blinking fast Blinking fast Module in pre-operative stage. Module error.
Blinking fast OFF Module in pre-operative stage. Module error.
TX overflow RX overflow Meaning.
OFF OFF Module turned off or in initializing stage.
- - - ON Data reception error.
ON - - - Data sending error.
Blinking fast Blinking fast Too many errors at the node.
Led I/O. Meaning.
Off. There's no data at the data bus.
Green. The module is transmitting data.
Red. Hardware error.
