In this chapter you will learn the methods to address slaves by means of the con-
trollere.
i
Tip
To allow the AS-i master to communicate with each individual slave, each address
must only occur once in the system.
Slaves with the address 0 do not operate on the bus.
On delivery, the AS-i slaves always have the address 0.
The controllere displays an error message and does not process slaves with
wrong addresses or addresses which have been assigned twice.
Permissible slave addresses
Single slaves
(0), 1...31
A/B slaves
(0A), 1A...31A, 1B...31B *)
•
If an address has been assigned for a single slave, this address must not be
assigned as an A or B address at the same time. Addresses assigned for A/B
slaves must not be also assigned for single slaves.
Example of non permissible address assignment: 17, 17A
•
If an address has been assigned for 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
*) The address 0B is not possible.
