Beckhoff Bus Coupler
The BK51x0 Bus Coupler and the IPxxx-B510 Fieldbus Box are installed in the CANopen bus. The specific properties which distinguish them from other Bus Couplers and/or Fieldbus Box modules are then described below.
BK51x0/IX-B510 tab
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 analog and special signals. If more than 64 digital signals are present, they also furnished with this inhibit time.
Event Time: Event timer for transmit PDOs. Expiry of this timer is treated as an additional event for the corresponding PDO, so that the PDO will then be transmitted. If the application event occurs during a timer period, it will also be transmitted, 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 / analog input telegrams. 254 + 255 corresponds to the event-driven transmission, 1...240 are synchronous transmission types. For further details see also BK51X0 manual.
Firmware Update: Enables the updating of the coupler firmware via the serial interface (requires KS2000 software package interface cable).
SDOs tab
SDO inputs sent to the node at StartUp are displayed/managed on this page. Inputs with an object index in straight brackets are automatically created on the basis of the updated terminal configuration. Other inputs can be managed using "Append", "Insert", "Delete" and "Edit".
ADS tab
The node (Bus Coupler) is assigned an ADS port to enable writing and reading of SDO objects at runtime (e.g. from the PLC). It can be changed if required. The ADS IndexGroup contains the CANopen object index and the ADS IndexOffset contains the CANopen SubIndex. See chapter SDO communication for details of SDO communication via ADS.
Diag tab
Diagnostic information is displayed here. The window contents are not cyclically refreshed; select the "Refresh" button if necessary. The diagnostic information displayed can also be queried by ADS.
