Where do I specify which I&M data is downloaded to which PROFINET IO devices?
You specify which I&M data you want to download to which PROFINET IO devices in the "Load
preview" dialog. You will find the following alternatives in the drop-down list of the
"Identification and maintenance data (I&M)" row:
•
Load nothing
The check boxes for all PROFINET IO devices as well as the check boxes for the loadable
I&M data are cleared.
No I&M data is transferred to the actual hardware during loading with this setting.
• Load data
The check boxes for all PROFINET IO devices as well as the check boxes for the loadable
I&M data are selected.
The respective I&M 1, I&M 2 and I&M 3 data is transferred to all PROFINET IO devices
during loading with this setting.
• Load selected
You select the check boxes of those PROFINET IO devices to which you want to load
I&M data. You also select the check boxes of the identification data you want to load.
With this setting, you transfer the selected I&M data to the selected PROFINET IO devices
during loading.
Note
Language dependency of the I&M data to be loaded
The I&M data are loaded to the real hardware in the form that you specified in the properties
of the relevant PROFINET IO devices and your modules. There is no language dependency.
4.9.3 Asset management
4.9.3.1 Further information about asset management at PROFINET
Operation of machines and plants without a detailed knowledge of devices and assets is
difficult to imagine.
Maintenance requires data for this – data that is extensive and up-to-date as far as possible.
The requirement of greater transparency with regard to the data made available by plant
components has been fulfilled by PROFIBUS & PROFINET International (PI): The identification
and maintenance data familiar since PROFIBUS times have been extended.
The current PROFINET fulfills this requirement through the definition of a special data record:
the Asset Management Record (AMR).
The aim of this definition is to enable you to acquire
all the components to be maintained
online - and not only those components that can be addressed and accessed through the
PROFINET device model (Device / Module / Submodule). PROFINET now also reaches non-
PROFINET components!
