Product Description:
The CX1500-B310-0002 is a fieldbus interface module produced by Beckhoff for the CX Embedded PC Systems series. Designed for mounting beside a CX CPU, the unit adds PROFIBUS communication to a control architecture so that the embedded PC can exchange cyclic and acyclic data with distributed I/O stations, drives, and sensors. By providing a direct hardware gateway, the module lets the controller participate in deterministic plant networks without requiring an external gateway, and it preserves cabinet space in compact machines where side-by-side mounting is important. That arrangement keeps the communication interface within the same controller assembly instead of adding separate network hardware elsewhere in the cabinet.
Communication is handled through a 1 x D-Sub socket that follows the PROFIBUS DP electrical standard. The connector is configured as a slave station, so the CX controller responds to telegrams initiated by a class-1 master. It uses a 9-pin layout with the pinout 1=Shield; 3=P; 5=GND; 6=+5 VDC; 8=N for the bus and reference connections. Beckhoff also indicates drop-cable colors as B = red on pin 3 and A = green on pin 8, which helps confirm polarity at a glance. This wiring format supports straightforward integration into existing PROFIBUS segments without adding special interface hardware.
The module also keeps a compact housing for rail-mounted systems. A casing width of 38 mm leaves DIN-rail space for additional I/O slices, while the overall height of 100 mm aligns with the CX CPU so ventilation slots remain unobstructed. The enclosure depth of 91 mm keeps the PROFIBUS plug within the cabinet footprint and helps avoid interference with the door or nearby wiring. Matching the CPU height also keeps the controller assembly even across the front face, which helps maintain clear access to adjacent terminals. Inside the backplane, the device uses ISA base address D6000, which reserves a contiguous register block for process data and diagnostic flags without overlapping neighboring modules.
