4.1.1.5.3 PI Mapping
To undertake settings on the "PI mapping" (process image mapping) page, the
process image size of the master must first be set.
Use the [Data Frame] button in the symbol bar to open the dialog for entering
the process image and mailbox sizes (see Figure 28).
Figure 28: Determine data framework g064444e
The following settings are possible (see Table 29):

Toggle field Settings
Process image size
12 bytes, 24 bytes, 48 bytes*
Mailbox size
6 bytes, 12 bytes, 18 bytes*
* Standard setting
Button Description
[Apply]
Transfers the altered parameters to the module's permanent memory. A
software reset is conducted so that the changes take effect. The dialog
remains open.
[Default]
Selects the standard setting for this module. Then transfer the parameters
to the permanent memory of the module by using the [Apply] button.
[Close]
Ends the parameterization dialog without transferring any altered pa-
rameters to the permanent memory of the module.
Note
Please note that the structure of the process image changes when the process im-
age size or mailbox size is changed. Therefore, changes in the configuration of
the superordinate control may be necessary.
On the "PI mapping" page, the slave process data is allocated to the slots in
the master (see
Figure 29). Up to 46 bytes of the process image are available
for this purpose (depending on which process image size was set in the "Data
framework" dialog). The control/status byte and internal byte are not taken
into consideration here.
