Chapter 6 Micro870 Controller Distributed Network Protocol
2080-L70E-24QxBN controllers, a Data-Set event can consume multiple
numbers of the event buffers.
If the number of the generated events reaches this value, the controller sets
IIN2.3 [EVENT_BUFFER_OVERFLOW]. Further events are not logged until
the logged events are reported to DNP3 Master and the buffer is available.
The logged events are not removed until they are reported to DNP3 Master
successfully. Logged event can also be cleared when one of the following events
occur:
• New OS firmware upgrade
• New user program download.
Figure 6
shows how to generate events for a Binary Input Object and a 16-bit
Analog Input Object. In the DNP3 Slave configuration, Binary Input Object
Data and 16-bit Analog Input Object Data is configured in the DNP3 mapping
table.
Figure 6 - Generate Events for Binary Input Object
Click Add to select, or create a binary variable from the variable selector screen
for the Binary Input Object.
There are two methods to create Binary Input Object. You can create the object
as a BOOL data type or as an UINT data type. The UINT data type represents
similar to a BOOL array of 16 bits and this representation is similar to the
BOOL array used in MicroLogixâ„¢ 1400 controllers.
