Tab. 2.2 Diagnostic information
Festo – MSE6-E2M-IN-EN – 2017-07c – English
Common diagnostic messages (global error messages) are displayed by
means of 8 internal inputs (8 status bits).
With fieldbuses that do not possess extensive diagnostic functions, the
diagnostic information of the MSE6-E2M is available via the I/O diagnostic
interface. The I/O diagnostic interface enables bus-independent access to
diagnostic information, data and parameters via internal digital I/Os
(16 inputs and 16 outputs).
Errors which occur during operation are entered in a diagnostic memory.
The first or the last 40 entries are saved, as well as the respective time
measured from the moment the power supply was switched on.
Special diagnostic functions or communication services are available,
depending on the fieldbus used.
