Explicit Messaging

Explicit Messaging is used in commissioning and parameterizing of the EtherNet/IP board.
The explicit messages provide multipurpose, point-to-point communication paths between two
devices. They provide the typical request/response-oriented network communication used to
perform node configuration and problem diagnosis. The explicit messages typically use low priority
identifiers and contain the specific meaning of the message right in the data field. This includes the
service to be performed and the specific object attribute address.
NOTE! If Class 1 connection (cyclic data) has been established, the Explicit Messages should not be
used to control the Output Data. However this restriction does not apply for the IO Data reading.
