DF1 Diagnostic Sequence Count

Allen-Bradley · Compact 5000 I/O Serial Module

Hva betyr I x .DF1.DiagnosticSequenceCount ?

This SINT tag for module 'x' increments each time a unique diagnostic condition is detected or transitions from active to inactive on the DF1 channel. It acts as a change counter for diagnostic states, providing a means to track the frequency and occurrence of diagnostic events. The count resets to zero upon product reset or power cycle, and wraps from 255 (-1) to 1, skipping zero.

Vanlige årsaker

  • Occurrence of a new distinct diagnostic condition on the DF1 channel of module 'x'.
  • Resolution of a previously active distinct diagnostic condition on the DF1 channel of module 'x'.
