Beckhoff FC510x as a CANopen Monitor
As from firmware version 1.00 and TwinCAT 2.8 (Build 738), the FC5101 and FC5102 can be used as CANo-
pen monitors instead of masters.
For instance, the second channel of the FC5102 can be used for this purpose, while the first channel continues
to function as a CANopen master, or vice versa. In such a case, both channels must be connected to the same
CAN network. (Data exchange within the card is not provided, since this cannot take place without interactions.)
The telegrams recorded by the FC510x are temporarily stored in a ring buffer by the task linked with the
FC510x; the stored telegrams can then be accessed by ADS. There is a CANopen monitor program (CAN-
MON) offering filter and trigger facilities available as freeware from Beckhoff. The user's own applications may
also access the monitor data using the ADS interface described below.
Inserting the FC510x as a CANopen Monitor
In the Insert device context menu: insert CANopen monitor
After this it is necessary to select the appropriate channel (PCI memory address).
Linking the FC510x with a task
The monitor data is accessed at the start of a task from real-time TwinCAT. For this purpose it is necessary to
create an additional task in the system manager, containing at least one UINT16 input variable that is to be
linked to one of the variables in the FC510x.
