Diagnostics and fault clearance
37
When the number of diagnostics messages reaches 250, old diagnostics messages are overwritten.
–
Acknowledge Mode:
A diagnostics message must first be acknowledged before it can be overwritten with a new diag-
nostics message. When the number of unacknowledged diagnostics messages reaches 250, new
diagnostics messages will not be saved and will be lost.
Mapping "New message available" message
For simplification of the diagnostics evaluation, the module offers the option of signalling the exis-
tence of a new diagnostics message via the process data. To do this, the "New message available"
object can optionally be mapped to the process data.
Deactivate/activate Emergency message
The sending of one Emergency message can be deactivated and activated via object 0x10F3 (subindex
5, bit 0).
