2.4.3 Bus start-up

2-16
The bus node can be controlled by commercially available
programmable logic controllers (PLC) aw well as PCs and in-
dustrial PCs with a PROFIBUS-DP interface in accordance with
EN 50170. The corresponding programming and commission-
ing software of your PLC manufacturer is required for com-
missioning.
Configuration of the bus node with a PLC from Siemens is
described in chap. 2.4.4.
In order to commission the mounted and connected bus
node, the master must carry out the following functions in the
corresponding sequence:
1. Request diagnostic information
2. Send parameterisation data (Set_Prm)
For the start parameterisation, the parameter set is
loaded by the master into the bus node. The bus node
distributes the parameters to the connected equipment.
3. Check configuration data (Chk_Cfg)
4. Transfer input and output data (cyclical data exchange,
Data_Exchange)
5. Read diagnostic information (Slave_Diag)
The structure and contents of the individual telegrams are
described in the appendix.
Note
After each interruption of fieldbus communication, the
parameter set is resent to the bus node by the master.
