3.1 DPV1 ACYCLIC DATA EXCHANGE
The software of the module implement the DP standard/DPV1 functionality for communication of the slave
with a Class 1 (parameterization) Master and a Class 2 Master.
With the Acyclic Service of data exchange and with the Acyclic Slot and Acyclic Index it is possible to
send and return configuration parameters from the Flow meter with a Class 1 (parameterization) Master and
a Class 2 Master.
For the communication with a Class C1 master the Slot is ignored.
Only Slot 0 is used for the Acyclic Service of data exchange for the comunication with a Class 2 master.
3.2 Acyclic Read Data from the Flow Meter
For return data with the Acyclic Read Service and a Class 1 Master the Acyclic Slot is ignored and every
value is not checked in the slave. The only value used for select the data is the Acyclic Index.
If the master is a Class 2 master, it is necessary insert the value of the Acyclic Slot = 0 and with the value
of the Acyclic Index there is the selection of the data returned.
Below there is the description list of the type of the bytes returned with the different value inserted in the
Acyclic Index.
