GMT Event Element Data Object (EventElement870)
EventElement870 is a low-level data object that holds and organizes all the data
required for a single GMT time-stamped event. This low-level structure is used by
the mid-level EventType870 data object to create an array of up to ten (10)
events that can be moved to the module in a single output data block transfer.
Name Data Type Description
DBIndex INT Point index in the module's database -
Corresponds to the order of point definition in
the Data Type section of the configuration file
ASDU INT 1=M_SP, 3=M_DP, 5=M_ST, 9=M_ME_NA,
11=M_ME_NB, 15=M_IT
Qualifier INT Qualifier code used for ASDU types 5, 9, 11
and 15
Year INT Event Year ( four digits year ex: 2006)
Month INT Event Month (1 to 12)
Day INT Event Day (1to 31)
Hour INT Event Hour (0 to 23)
Minute INT Event Minute (0 to 59)
Seconds_Milliseconds INT Event Seconds and Miliseconds in scaled
integer format (0 to 59999) Example =>
59999 = 59 seconds and 999 milliseconds
Data INT[6] Data associated with the event (point value)
Event Block 9958 for UTC Time Data Object (EventTypeUTC870)
The EventTypeUTC870 mid-level data object is used as part of the higher-level
Control870 data object. EventTypeUTC870 uses the lower-level
EventElementUTC870 data object as part of it's structure.
EventTypeUTC870 is one of two data structures that support moving time-
stamped events from the processor to the module so those events can be
transmitted on the IEC-60870-5-104S network. The EventTypeUTC870 structure
is the one to use when events carry a date and time stamp formatted as
Coordinated Universal Time (UTC), such as event data received from Rockwell
Automation 1756 SOE Sequence of Events modules. This structure can hold up
to ten (10) separate UTC time-stamped events in an array based on the
EventElementUTC870 data object. Using this structure, up to ten (10) events can
be sent to the module in the place of one regular output data image block.
Name Data Type Description
EventCommand_GMT BOOL Set to 1 to trigger Block 9958 (GMT Event
Block) data transfer
EventCount_GMT INT Number of events to be sent in current 9958
block
Event_GMT EventElement870[10]
See the description of the EventElement870 (page 62) data object for details
about the data sent as part of a GMT time-stamped event.
