Communication via PROFIBUS
Commissioning PROFIBUS
Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for
remote diagnosis purposes.
Setting the PROFIBUS address
The following two options are available for setting the PROFIBUS address:
1. PROFIBUS address switches on the Control Unit
– In this case, p0918 is read-only and simply displays the set address.
– A change is not effective until POWER ON.
2. Via p0918
– You can only use this method when all the PROFIBUS address switches
from S1 to S7 are set to ON or OFF.
– A change is effective immediately.
Example:
Setting the PROFIBUS address using the PROFIBUS address switches on the
Control Unit.
Fig. 4-6
Note
Parameter p0918 is unique to the Control Unit (see Control Unit). The factory
setting is 126.
Permissible PROFIBUS addresses are 1 to 126. Address 126 is intended for
commissioning.
The address setting on the switch is displayed in p0918.
A change in the switch setting is not effective until POWER ON.
The factory settings are "ON" or "OFF" for all switches. With these two settings,
the PROFIBUS address is set via parameters.
