mbus CSDB Send Labels At Rates.vi
Description
CSDB Sent Labels At Rates VI transmits labelCount periodic CSDB messages onto any port with adjustable message rates.
The SI Discriminate parameter is an optional parameter.
When SI Discriminate is set to true, the scheduler treats outgoing messages using the same label but different Source Identifiers (SI) as separate messages.
The SI is the two Least Significant Bits of the status byte. It serves as a label extension and can help differentiate two identical units in the same environment.
When SI discrimination is enabled, the pair label-SI are the message ID and each label-SI pair can have its own rate.
