Beckhoff FC510x Hardware Description
The FC510x is a CANopen Master card with one (FC5101) or two channels (FC5102). The CAN transceivers are galvanically isolated.
CAN Terminating Resistor
On the card there are CAN terminating resistors (120 Ohms). These can be activated with a jumper (up to hardware version 3) or with a switch (from hardware version 4) close to the CAN connectors.
The Flash Disk Socket is currently not in use.
Pin assignment
The CAN bus line is connected via 9-pin D-Sub sockets with the following pin assignment.
Pin | Assignment |
|---|---|
2 | CAN low (CAN-) |
3 | CAN Ground (internally connected to pin 6) |
5 | Shield |
6 | CAN Ground (internally connected to pin 3) |
7 | CAN high (CAN+) |
The unlisted pins are not connected.
 | Auxiliary voltage An auxiliary voltage of up to 30 VDC may be connected to pin 9. Some CAN devices use this to supply the transceiver. |
LED Behavior
The red ERROR LED and the green RUN help to quickly diagnose the status of the card:
Error LED (red) | Run LED (green) | Description |
|---|---|---|
off | off | TwinCAT has been stopped |
off | on | All configured bus nodes are error free (Box State=0), TwinCAT Task or Process is running. |
off | blinking with 2 Hz | The Task, whose process data is linked to the card, is not running. |
blinking with 2Hz | on | At least one box state is unequal zero (e.g. node not found, wrong configuration, node in error), TwinCAT Task is running |
blinking with 2 Hz | off | At least one box state is unequal zero (e.g. node not found, wrong configuration, node in error), TwinCAT Task is not running |
on | off | TwinCAT is running, CAN Controller is "Bus OFF". Physical CAN problem. Possible reasons: e.g. terminating resistor missing, bus too long, wrong baud rate, node address configured twice, short circuit, wiring error. Restart is necessary |
blinking with 20Hz | blinking with 20Hz | Configuration Upload is under way |
blinking with 20Hz | off | card is in STOP mode |
