Addressing the data using acyclic services
The data-addressing is done per module by means of the following details:
slot
index
length
The slot-number addresses the module and the index addresses the module’s parameters.
Each data block can have a maximum size of 240 bytes.
In case of a successful data access, the slave sends a positive answer. If the data access
failed, a negative answer which classifies the problem precisely is sent.
