Diagnostic Buffer Support

A diagnostic buffer is a list of alarm records that is stored internally on a number of PLCs that support a diagnostic buffer. This is configured and managed by the software application Unity Pro™.

For diagnostic buffer management, two sets of functions have been defined:

• Record Browsing Interface

  Functions designed to read diagnostic records from a PLC.

• Device Resynchronization Interface

  Functions designed to force the driver to resend the whole content of the diagnostic buffer.
