Event Log Register Block; Reading The Event Log - Grundfos CIM 200 Functional Profile And User Manual

9.16 Event log register block

The event log contains the latest 40 event entries. Each entry
consists of seven registers, containing information about the
event.

9.17 Reading the event log

The event log has a size of 282 registers containing the latest 40
alarm and warning events. The number of contained event logs
can be read from NoOfEventsInLog (register 06001).
Each event is represented as an event record of seven registers:
• EventID
• EventCode
• EventSource
• EventDeviceNo
• EventTypeAndCondition
• EventTimeStampHI
• EventTimeStampLO.
The EventID is a unique "tag" for the event record. These IDs are
incremented successively corresponding to the succession of the
events they represent. The event log can be handled in three
ways:
• Reading the complete log, all 40 event records, regularly and
afterwards sorting "new" ones from "old" ones.
• Reading the event ID of the latest record (EventLogLatestID,
register 00216) and comparing it with the event ID of the
previously read record to see how many "new" records are
generated. Then afterwards reading only the "new" ones.
• Clearing the event log with Control.ResetEventLog (register
00101, bit 2) after it is read. Then afterwards the event log will
contain "new" events only.
The CIM module ensures that logged data are
protected against internal updates during the time
they are accessed from Modbus, so that the event
log constitutes a time-consistent block (data
coherency).
