Following successful initialization, the PROFIBUS service
D Write_Read_Data/Data_Exchange (Default_SAP)
ensures that data is exchanged between the master and the slave.
This process takes place in a fixed, repetitive sequence and is automatically
initiated by the master. The master sends the "setpoint telegram" to the
slave, and in return, it expects its "actual value telegram".
Display H1 on the inverter shows the value "4" in this condition.
You may display on the DSS the data that is exchanged:
.
S-0-0024 (configuration list for master data telegram) contains the
numbers of all parameters sent by the master to the slave.
S-0-0016 (configuration list for drive telegram) contains the numbers
of all parameters sent by the slave to the master.
In the event of diagnostics messages or errors: refer to section 3.5 on
