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, Promag 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 Promag 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 Promag 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 Promag 500.
The functions are supported as follows depending on the previous model:
Previous model: Promag 50 PROFIBUS DP
Control variable Function Support
0 → 2 Positive zero return: ON Yes
0 → 3 Positive zero return: OFF 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: Promag 53 PROFIBUS DP
Control variable Function Support
0 → 2 Positive zero return: ON Yes
0 → 3 Positive zero return: OFF Yes
0 → 5 Electrode cleaning circuit (ECC): OFF Yes
0 → 6 Electrode cleaning circuit (ECC): ON 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.
0 → 50 Relay output 1: ON Yes, terminals 24/25 (I/O 2)
0 → 51 Relay output 1: OFF
