AUMA AUMATIC ACExC 01.2 User Manual

3.3. Bus address (slave address)
Each participant at the bus is addressed via its specific bus address (slave address).
The bus address may be assigned only once per fieldbus network.
The bus address is stored in a non-volatile memory.
On delivery, address 126 (default value) is set for all devices.
The bus address (slave address) can be set in the following ways:
●
Locally via push buttons (indication in the display).
For details on setting refer to the operation instructions to the actuator or
Manual (Operation and Setting) AUMATIC AC 01.1 Profibus DP.
●
Using the AUMA CDT service software (via PC or laptop with Bluetooth).
The latest version of the AUMA CDT can be downloaded from our website:
www.auma.com.
●
Via fieldbus. Please note that only one device with the address 126 (default
value) may be connected to Profibus DP. A new bus address may be assigned
to the actuator using the SAP 55 (Service-Access-Point Set Slave Address).
For redundant version according to Profibus DP-V2 redundancy, only the address
of the primary channel can be set; the address of the backup channel is derived from
the primary.
For redundant version according to AUMA redundancy, the addresses of both
channels can be set individually.
3.4. Configuring the Profibus DP interface
During configuration, the number of input and output bytes reserved for each device
in the controls’ memory is selected. Additionally, the method of data processing is
defined: consistently or non-consistently.
Information Only the number of bytes determined in the configuration is transferred between DP
master and DP slave.
