Compatibility to the previous model Promag 35
(Profile Version 2.0)
Promag 35 with Profile Version 2.0 is the precursor to the Promag 55. If Promag 35 is already being
operated in the system and the measuring device has to be replaced, Promag 55 can be used as a
replacement device without having to reconfigure the PROFIBUS network. In the event of a device
being replaced, Promag 55 completely supports the compatibility of the cyclic data with the previous
Promag 35 model.
The measuring devices can be exchanged as follows:
Promag 55 is accepted as the replacement device if the MANUFACT V2.0 option is activated in the
SELECTION GSD (6140) function. The measuring device automatically detects that a Promag 35
device was configured in the automation system and makes both suitable input and output data and
measured value status information available even though the devices differ in name and ID number.
You do not have to adjust the configuration of the PROFIBUS network in the automation system.
Procedure after replacing the measuring devices:
1.
Set the same (old) device address
→
FIELDBUS ADDRESS (6101) function
2.
In the SELECTION GSD (6140) function
→
Select MANUFACT V2.0
3.
Restart the measuring device
→
SYSTEM RESET (8046) function
!
Note!
If necessary, the following settings have to be configured via an operating program:
• Configuration of the application-specific parameters
• Configuration of the system units for the measured values and totalizers.
6.6.4
Maximum number of writes
If a nonvolatile device parameter is modified via the cyclic or acyclic data transmission, this change
is saved in the EEPROM of the measuring device.
The number of writes to the EEPROM is technically restricted to a maximum of 1 million. Attention
must be paid to this limit since, if exceeded, it results in data loss and measuring device failure. For
this reason, avoid constantly writing nonvolatile device parameters via the PROFIBUS network!
