Proline Promass Q 500 PROFIBUS PA System integration
Hauser 89
2. Set the device address: The same device address that was set for the Promass 80 or
Promass 83 PROFIBUS PA must be used.
3. Connect the measuring device Promass 500 PROFIBUS PA.
If the factory setting had been changed on the replaced device (Promass 80 PROFIBUS PA
or Promass 83 PROFIBUS PA), the following settings may need to be changed:
1. Configuration of the application-specific parameters.
2. Choice of process variables to be transmitted via the
Channel parameter in the
Analog Input or Totalizer function block.
3. Setting of the units for the process variables.
9.4 Using the GSD modules of the previous model
In the compatibility mode, all the modules already configured in the automation system
are generally supported during cyclic data transmission. However, Promass 500 does not
perform further processing for the following modules, i.e. the function is not executed:
• DISPLAY_VALUE
• BATCHING_QUANTITY
• BATCHING_FIX_COMP_QUANTITY
If the device is replaced, the measuring device Promass 500 supports the compatibility of
the cyclic data with previous models. It is not necessary to adjust the engineering
parameters of the PROFIBUS network with the Promass 500 GSD file.
9.4.1 Using the CONTROL_BLOCK module in the previous model
If the CONTROL_BLOCK module is used in the previous model, the control variables are
processed further if relevant functionalities can be assigned for the Promass 500.
The functions are supported as follows depending on the previous model:
Previous model: Promass 80 PROFIBUS PA
Control variable Function Support
0 → 2 Positive zero return: ON Yes
0 → 3 Positive zero return: OFF Yes
0 → 4 Zero point adjustment: START Yes
0 → 8 Measuring mode: UNIDIRECTIONAL No
Cause:
The Profile Transducer Block Flow is no
longer supported.
To continue to use the functionality:
Use the Totalizer operation mode
parameter in the Totalizer function block.
0 → 9 Measuring mode: BIDIRECTIONAL
0 → 24 UNIT TO BUS No
Cause:
Functionality is no longer required as the
unit is adopted automatically.
Previous model: Promass 83 PROFIBUS PA
Control variable Function Support
0 → 2 Positive zero return: ON Yes
0 → 3 Positive zero return: OFF Yes
0 → 4 Zero point adjustment: START Yes
