The assembly object is configured according to the attributes of
the bus coupler. The I/O data object is mapped into the
assembly object by default.
The RMV04-DN assembly has:
W
3 Byte outputs (Consuming Data Bytes)
W
No inputs (producing data bytes)
It is possible, however, to map the diagnostic data into the
assembly object behind the input data (settings in the MCR -
module control register). In this case, the number of producing
data bytes = 1 byte.
Class 0x04, instance 0x24, attribute 0x03
