The implementation integrates the commercial TMG PROFIBUS DP slave protocol stack on Freescale’s QorIQ P1025 multicore processor in a Freescale Tower System development platform module called the TWR-P1025, and covers layer 2 to layer 7 of the PROFIBUS standard.
“For the first time, our customers can combine their control application simultaneously with PROFIBUS and/or PROFINET industrial protocols using a single Freescale processor,” said Nikolay Guenov, marketing director for Freescale’s Networking Processor Division. “This PI-certified reference platform helps reduce chip counts and system costs by connecting the QorIQ P1025 processor directly to an RS-485 transceiver, thereby eliminating the need for separate PROFIBUS ASICs or FPGAs.”
The code developed for the TWR-P1025 can port to other QorIQ P1 family processors as well as Freescale’s MPC8309 PowerQUICC processor which are all in Freescale’s longevity programme.
For PROFIBUS evaluation, the TWR-P1025 controller module is enabled with an executable version of the TMG PROFIBUS software stack, Freescale PROFIBUS layer 2 microcode and applications programming interface (API) source code.
The Freescale PROFIBUS reference platform is available now for purchase from Freescale or its distribution partners, by ordering the TWR-P1025-KIT at an MSRP of $299. The kit includes a TWR-P1025 processor module, TWR-IND-IO peripheral module, and TWR-ELEV elevator/backplane modules. The QorIQ P1025 and its single-core equivalent QorIQ P1016 processor are available now starting from an MSRP of $35.16 and $29.89 in quantities of 10,000 units. The MPC8309 processor is available now at an MSRP of $8 in quantities of 10,000 units. The commercial TMG PROFIBUS DP protocol stack is available from TMG.
