4 On-Board LEDs
The TMCM-1310 offers four LEDs for indicating EtherCAT communication and board status. The three green
LEDs are related to the EtherCAT interface and indicate EtherCAT LINK IN and LINK OUT activity plus the
status of the EtherCAT state machine. The function of the red LED is depends on the firmware version.
With standard TMCL firmware the red Error-LED should be flashing slowly during operation. When there
is no valid firmware programmed into the board or during firmware update the red LED will be
permanently on.
