BECKHOFF EtherCAT IP Core for Altera FPGAs v3.0.10 - Manual (Page 46)

IP Core Configuration
III-34 Slave Controller – IP Core for Altera FPGAs
5.2 Parameters
5.2.1 Product ID tab
Figure 9: Product ID tab
PRODUCT_ID input in hexadecimal groups
The Product ID can be chosen freely and is for vendor issues. It can be read out in register
0x0E08:0x0E0F.
The PRODUCT_ID has to be entered in hexadecimal format for each of the four 16 bit fields
(representing a 16 bit part of the 64 bit Product ID each).
The Product ID is meant to identify special configurations of the IP Core. It does not have to reflect the
EtherCAT slave product code, which is part of the EEPROM/XML device description.
NOTE: The current GUI seems to allow 32 bit entries for each of the 4 16 bit fields, but this is not true. This is an
Altera MegaWizard configuration restriction.
