Product Description:
The CX1500-M510-1002 is a plug-in fieldbus interface manufactured by Beckhoff for the CX Embedded PC Systems series. The unit is inserted on the left side of the CX system and serves as a CAN controller that links the embedded PC to a CANopen network used for drives, sensors, or distributed I/O in industrial automation. By providing direct read-and-write access to process data through its onboard dual-port RAM, the module allows the central CPU to supervise and modify remote node parameters within one deterministic scan cycle.
This interface operates in CANopen Master mode, so it initiates bus transactions and manages network timing. Internal data buffering is handled by a DPRAM block with a capacity of 0x2000 bytes. The controller CPU can access that memory through a simple R/W operation without additional handshaking. The CAN line terminates on a single 9-pin D-sub connector. Pin 7 carries the CAN High signal, while pin 2 carries CAN Low and pin 5 connects the cable shield to the housing ground. Communication follows the CANopen protocol profile, so standard PDO and SDO services are available for cyclic process data and configuration messages.
The module measures 38 mm wide, 91 mm deep, and 100 mm high. Its compact width conserves cabinet space, while the housing depth leaves clearance for the mating plug and its height aligns with the CX system form factor. Connector pins 1, 4, 8, and 9 are left unconnected. Pins 3 and 6 serve as system grounds and provide the required reference potential. The shared memory architecture enables the bus controller and central CPU to exchange data directly without relying on interrupt-driven transfers. This arrangement supports predictable access to incoming process values and outgoing control data during each automation cycle.
