Charms SLS Internal System Architecture

One of customer in India has requested for internal system architecture of Charms SLS.

I know it is equivalent to SLS1508 (Dual/TMR/QMR capability).

But need a document which confirms this for C-SLS.

  • Very similar to SLS1508. There is no EMR document to describe the CSLS. Don't think we provide internal architecture. TUV report has some description.
    Each CSLS run two control subsystem executing user configured logic in different/independent ALUs (Dual processing) and compare each control subsystems outputs. If there is an error/mismatch, the CSLS initiates a output shutdown or the redundant CSLS partner will continue driving the output.
    - Simplex CSLS, Dual processing.
    - Redundant CSLS, Quad processing.
  • In reply to Vignes Kalimuthu:

    I'm pretty sure that was working on an architecture document, but it might be something that we would share on a more limited distribution.
