COMMUNICATION SETUP
0BDNP3 PROTOCOL PROFILE
The use of SBO mode is recommended, as it provides greater reliability than the other
two. However, there are situations where the use of even the less secure of them (direct
operation without acknowledge) is required, e.g. when trying to give the same command
to a group of relays. In this case, the order is sent using the broadcast address of DNP3
and does not require any answer to prevent loss of data that would occur in RS-485
links if multiple devices respond simultaneously
The configuration of the outputs operation mode is applied to all the configured outputs.
It is not possible to configure different operation modes for each output.
4.7.5. FORMAT FOR ANALOG VALUES
In this box the variation that the relay uses when it receives a request using the variation
0 for the object 30 and in scans of class 0 and 2 (analog values) can be chosen. The
user can choose between 16 and 32 bits. If the user intends to use 32 bits, he/she will
most likely need to define the full-scale values and behaviour to ensure that the analog
16-bit is set to “Scale” not to “Report overflows”.
4.7.6. 16 BITS VARIATIONS RESPONSES
In this box the behaviour of the smART P500 for analog variable requests using
variation 0, is configured. In the documentation of DNP3, variation 0 is used to request
that the device responds with the most appropriate variation or native.
When using the 16 bits variation, selecting “Scale” is recommended as well as defining
the full scale values so that the obtained values are useful.
