2.5 Slave profile
Each slave is marked with a specific profile to assure unequivocal identification by the AS-Interface mas-
ter. This profile is permanently programmed by the manufacturer and cannot be changed. The conditions
for this are listed in the AS-Interface specifications. The profile consists of one data byte including the
identification code (ID-Code) as well as the Inputs/Outputs code (I/O-Code). These data determine the
slave function ("ID-Code") and the I/O configuration ("I/O Code").
The slave profile information (ID- and I/O-Code) is very important for an easy replacement of slaves in the
system. It enables the master to check if the current configuration corresponds to the reference configura-
tion.
2.6 Adressing
Fig. 2-7 : Manual addressing device
Each slave must be programmed with a unique address before setting up the AS-Interface system. To do
so, you can use an addressing device
4
or perform this configuration online via the master. Refer to the
corresponding description.
Addresses are non-volatile : they remain stored even in case of power cutoff
and can be changed a least 15 times per slave.
Slaves conforming to the specification 2.1 are fitted with a chip including an
EEPROM to store addresses. Addressing is not limited for such slaves.
