Meaning of the ID code (selection)
Structure slave profile = S-x.[ID-Code].x
ID code
(hex)
ID code
(bits 3…0)
Description
0
0000
4 I/O connections for binary sensors and/or actuators with 1 signal each
1
0001
2 dual-signal I/O connections for binary sensors and/or actuators with 2 signals each
A
1010
Slave operates in the "extended addressing mode" (B slave or A/B slave)
B
1011
Slave corresponds to "Safety at Work"
F
1111
Manufacturer-specific device (cannot replaced by products from other manufacturers)
Description of the extended ID code 1
Can be changed by the user, but is not part of the slave profile.
Default setting:
F
h
for standard slaves
7
h
for A/B slaves
The value is evaluated and checked by the master. The user can make an additional distinction
between slaves which do not differ in the AS-i system, e.g. slaves with different ranges for current,
voltage or frequency. This prevents damage when replacing slaves with a wrong range.
Description of the extended ID code 2
Extended ID code 2 for analogue slaves with profile 7.3.x
The extended ID code 2 is used to specify complex slaves.
Structure slave profile = S-7.3.[ext.ID code2]
