In this chapter you will learn the methods how to address slaves using the controllere.
NOTE
Every address is allowed in the system only once so that the AS-i master can communicate with
every slave individually.
Slaves with the address 0 do not operate on the bus.
The manufacturers of AS-i slaves always deliver their devices with the address 0.
The controllere displays an error message and does not process slaves with wrong addresses or
addresses which have been assigned twice.
11.2.1
Permissible slave addresses
Single slaves
(0), 1...31
A/B slaves
(0A), 1A...31A, 1B...31B *)
*) The address 0B is not possible.
If an address has been assigned to a single slave, this address must not be assigned as an A or B
address. Addresses assigned to A/B slaves must not be assigned to single slaves.
Example of non permissible address assignment: 17, 17A
If an address has been assigned to an A slave, this address may also be assigned as B address.
A/B slaves share one address number.
Example of permissible address assignment: 17A, 17B
Maximum number of slaves per master: 31 single slaves or 62 A/B slaves
