5-pin Open Style Connector
5-pin Open Style Connector
The left figure shows the socket in the BK51x0 Bus Coupler. Pin 5 is the connection strip's top most pin. Pin
5 is not used. Pin 4 is the CAN high connection, pin 2 is the CAN low connection, and the screen is
connected to pin 3 (which is connected to the mounting rail via an R/C network). CAN GND can optionally be
connected to pin 1. If all the CAN ground pins are connected, this provides a common reference potential for
the CAN transceivers in the network. It is recommended that the CAN GND be connected to earth at one
location, so that the common CAN reference potential is close to the supply potential. Since the CANopen
BK51X0 Bus Couplers provide full electrical isolation of the bus connection, it may in appropriate cases be
possible to omit wiring up the CAN ground.
ZS1052-3000 Bus Interface Connector
ZS1052-3000 Bus Interface Connector
The ZS1052-3000 CAN Interface Connector can be used as an alternative to the supplied connector. This
makes the wiring significantly easier. There are separate terminals for incoming and outgoing leads and a
large area of the screen is connected via the strain relief. The integrated terminating resistor can be switched
externally. When it is switched on, the outgoing bus lead is electrically isolated - this allows rapid wiring fault
location and guarantees that no more than two resistors are active in the network.

Setup of CX1500-M510 for CANopen
The module CX1500-M310 (master connection for Profibus) can, as all other modules of the CX-system, be
accessed via the TwinCAT System Manager. The user selects the desired system and search for units in the
System Manager (click with right button on I/O Units - this operation is only available in config-mode) After
some seconds the connected units are listed. The user selects the devices he / she wants to make use of in
the program.
