QUESTION:

How can you determine the I/O addresses of an AS-i slave regardless of the AS-i Master used when the initial address of the binary I/O area is known?

ANSWER:

When using an AS-i Master in automation systems, you must define an I/O address area for each AS-i Master in the hardware configuration. This results in a fixed binary I/O address area each of four input bits and four output bits for every possible standard slave (A slave) depending on the its slave address (1 to 31). In order to determine the address assignment of your AS-i slave relatively quickly during continued configuration, you can use the Excel table in the "Adressbelegung_ASI.zip" file below (address assignment_ASI). You just have to enter the initial address of the I/O area of the AS-i Master in Field 4 of the table. After transfer, the resulting address area of all possible AS-i slaves is displayed.
Download the "Adressbelegung_ASI.zip" file into a directory of your choice and then extract it. You can now use the Excel table.
