5.5.2 Requirements / proceeding with the SyCon System Configurator
The DP slave must support the DP
service “Set_Slave_Adr” (SAP55) and must be
connected with a DPM2 master, e.g. PC with Hilscher Master Card
“CIF50 PB”. So
that a MS2 connection can be established by the DPM2 master, a PROFIBUS-DP
system configuration must have been created! For this the GSD file associated to the
measuring system is required, see starting from page 90.
Figure 6: DP slave connection to Hilscher DPM2 master
Generally it is recommended to operate only one DP slave at the bus, to set the baud
rate to ≤ 187.5 kbit/s and to use short connecting cables to the DP slave.
During address assignment the DP s
lave must be in the condition “WAIT Parameter
(WPRM)”, which is present automatically after POWER ON/RESET. In this condition
no cyclic data between master and slave are exchanged!
For this, the following master settings must be performed in the SyCon System
Configurator:
Start SyCon System Configurator, mark the master symbol and select menu
Settings --> Master Settings…
. For the
Startup behaviour after
system initialisation
the function
Controlled release of the
communication by the application program
must be active. This
setting must be transferred to the master by means of menu
