  • September 3, 2021 kumkeo demonstrates mixed operation BiSS-C/EnDat 2.2 on PROFINET IRT

    kumkeo effectively processed BiSS-C and EnDat 2.2 measuring device signals in parallel on netX90,
    a multi-protocol SoC from Hilscher Gesellschaft für Systemautomation mbH. The transmission of measurement data in a PROFINET IRT telegram was synchronized at 250µs intervals.
    A Sinamics drive controller and a Speedgoat real-time-target machine were used to build the demonstrator.

  • August 18, 2021 kumkeo: Successful IO-Link Master Stack Integration on netX90 SoC

    In collaboration with TMG, kumkeo is the first company to successfully integrate the IO-Link Master Stack with the application core of the netX90 microcontroller. We used two Maxim MAX14819A dual-channel IO-Link transceivers to control up to four IO-Link devices.
    A board support package developed by kumkeo connects these transceivers to the Master Stack.
    Also created by kumkeo, the prototype board reaches cycle times of 1.3ms and 250µs offset to each other.

  • August 03, 2021 kumkeo: EnDat 2.2 Stack for netX90 SoC

    kumkeo is the first company to implement the EnDat 2.2 measuring device protocol on the netx90 microcontroller. The data recorded by two EnDat 2.2 measuring devices are transmitted to a PROFINET RT or PROFINET IRT telegram.
    If PROFINET IRT is used, the PROFINET stack runs in latched mode to synchronize both devices at 250µs intervals.

    The EnDat 2.2 Stack is currently in the qualification process and will be available for client applications soon.

  • June 18, 2021 kumkeo: Certified PROFINET module for netX 90

    kumkeo has continuously developed the PROFINET module for the netX 90 over the past several months. An alternative to PROFINET RT, the module facilitates communication via PROFINET IRT with cycle times
    of up to 250µs and a jitter of 1µs. ComDeC certified the correct functionality and durability of the PROFINET module in a client application in line with the toughest Conformance Class C and Netload Class 3 testing criteria. The test also included optional elements,
    like the dynamic submodule configuration and Fast Startup (FSU).
