Single-chip PROFIBUS Reference Platform for QorIQ and PowerQUICC Processors
The hardware platform for PROFIBUS evaluation is based on the TWR-P1025 module which is part of the NXP Tower System portfolio. The evaluation kit (TWR-P1025-KIT) comprises the TWR-P1025 processor module and TWR-IND-IO module for RS-485 connectivity. Module interconnect is provided by the TWR-ELEV elevator modules. The Tower System offers open source hardware, with schematic and layout design files provided on request to help speed the customer hardware design cycle.
With over 35 million installed nodes, PROFIBUS is the world’s most successful fieldbus (communication) technology used in industrial automation systems. Ongoing growth of around 10 percent per year is forecasted and this expansion is aided by the addition of PROFIBUS functionality to NXP’s PowerQUICC and QorIQ communications processors. The integration of PROFIBUS Layer 2 creates a single-chip solution with a direct connection to a RS485 transceiver. This eliminates the cost and board space associated with an external PROFIBUS ASIC, which is otherwise required.
Building on the versatility and long-term success of QUICC Engine technology, NXP offers PROFIBUS Layer 2 firmware for PowerQUICC and QorIQ processors with a QUICC Engine controller. This solution not only removes the need for a costly PROFIBUS ASIC, it also leaves the processor core almost entirely free for application processing.
QorIQ processors can also provide simultaneous support for Industrial Ethernet protocols like PROFINET, EtherCAT® and EtherNet/IP™.
Key Applications: Factory automation, Industrial control, Motion control, Process automation, Safety-critical applications, Transportation systems.
