BK51x0/LC5100/IPxxxx-B510 (CANopen)
The BK51x0 Bus Coupler and the IPxxx-B510 fieldbus box are installed in the CANopen bus. Those specific
properties which distinguish them from other Bus Couplers and/or Fieldbus Box modules are described below.
Following Bus Couplers are currently supported by TwinCAT:
Types Description
BK5100 Bus Coupler
BK5110 Economy Buskoppler
BK5120 Bus Coupler, successor of BK5100
LC5100 Low-cost Bus Coupler
IPxxxx-B510 Fieldbus Compact Box: CANopen in/output module, protection class IP67
ILxxxx-B510 Fieldbus Coupler Box: Expandable CANopen in/output module, protection class IP67

Node Id: Sets the node ID of the CAN bus device (between 1 and 63 (BK51x0) and/or 1 and 99 (IPxxxx-B510)).
This value must comply with the value set at the Bus Coupler and/or at the compact box.
Guard time: Cycle time for the node monitoring (node guarding).
Life time factor: Guard time multiplied produces the watchdog time for the monitoring of the master by the
coupler (life guarding). Life guarding is deactivated if the lifetime factor is set to zero.
Inhibit time: Displays the minimum send interval for PDOs (telegrams) with analogue and special signals. If
more than digital 64 signals are present, these are also provided with this Inhibit Time.
Event Time: Sets the Event Timer Value for Transmit PDOs. The expiration of this timer is regarded as addi-
tional event for the corresponding PDO. Thus the PDO is being sent. If the application event occurs during the
event timer period the PDO is sent as well and the timer is reset.
K-Bus Update: Calculates the anticipated duration of a complete update of the terminal bus (according to type
and number of connected terminals).
Trans.Type: Gives the Transmission Type for digital / analogue input telegrams. 254 + 255 corresponds to the
event-driven transfer, 1 … 240 are synchronous transfer types. For further details see also BK51X0 manual.
