9.3 Compatibility with earlier model
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.
Earlier models:
• Promass 80PROFIBUS PA
– ID No.: 1528 (hex)
– Extended GSD file: EH3x1528.gsd
– Standard GSD file: EH3_1528.gsd
• Promass 83PROFIBUS PA
– ID No.: 152A (hex)
– Extended GSD file: EH3x152A.gsd
– Standard GSD file: EH3_152A.gsd
9.3.1 Automatic identification (factory setting)
The Promass 500 PROFIBUS PA automatically recognizes the measuring device configured
in the automation system (Promass 80 PROFIBUS PA or Promass 83 PROFIBUS PA) and
makes the same input and output data and measured value status information available
for cyclic data exchange.
Automatic identification is set in the
Ident number selector parameter using the
Automatic mode option (factory setting).
9.3.2 Manual setting
The manual setting is made in the Ident number selector parameter via the Promass 80
(0x1528) option or Promass 83 (0x152A) option.
Afterwards the Promass 500 PROFIBUS PA makes the same input and output data and
measured value status information available for cyclic data exchange.
• If the Promass 500 PROFIBUS PA is acyclically configured via an operating program
(Class 2 master), access is directly via the block structure or the parameters of the
measuring device.
• If parameters have been changed in the device to be replaced (Promass 80 PROFIBUS PA
or Promass 83 PROFIBUS PA) (parameter setting no longer corresponds to the original
factory setting), these parameters must be changed accordingly in the new replacement
Promass 500 PROFIBUS PA via an operating program (Class 2 master).
Example
The setting for low flow cut off has been changed from mass flow (factory setting) to
corrected volume flow in a Promass 80 PROFIBUS PA currently in operation. This device is
now replaced by a Promass 500 PROFIBUS PA.
After replacing the device, the assignment for the low flow cut off must also be changed
manually in the Promass 500 PROFIBUS PA, i.e. to corrected volume flow, to ensure the
measuring device behaves identically.
9.3.3 Replacing the measuring devices without changing the GSD
file or restarting the controller
In the procedure described below, the device can be replaced without interrupting ongoing
operation or restarting the controller. However with this procedure the measuring device is
not fully integrated!
1. Replace the measuring device Promass 80 PROFIBUS PA or Promass 83 PROFIBUS
PA with a Promass 500 PROFIBUS PA.
