Value
DINT
Value for event
This information is passed to the processor from the module in a special read
block with an identification code of 9903. Each block can send up to 20 event
messages. Ladder logic must handle the receipt of this special data block and
place the data received into controller tags.
3.3.5 DNPEvent_Analog
The
DNPEvent_Analog
object encapsulates all the data values used with Special
Function Block 9959 to pass analog input event data from the processor to the
module. Up to ten analog events can be reported in each block, so this UDT
contains a ten-element array to preload the event data before sending the events
from the DNP slave port to a remote DNP Master.
Name Style
Description
Count
INT
Number of events (1 to 10)
SequenceCounter INT
Sequence counter for each block transfer. It is used to
synchronize and confirm receipt of the block by the
module.
