Compatibility to the previous model Promag 33
(Profile Version 2.0)
Promag 33 with Profile Version 2.0 is the precursor to Promag 53. If Promag 33 is already being
operated in the system and if the measuring device has to be replaced, Promag 53 can be used as a
replacement device without having to reconfigure the PROFIBUS network.
In the event of a device being replaced, Promag 53 completely supports the compatibility of the
cyclic data with the previous Promag 33 model.
The measuring devices can be exchanged as follows:
Promag 53 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 33 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.
6.5.4
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!
