Peripheral fault
A peripheral fault is shown on the master and on the slave by a red flashing LED.
Depending on the slave type it is possible to visualize an overflow, an overload of
the sensor's power supply or another fault regarding the peripheral equipment of
the slave.
Permanent configuration
The configuration data of all expected slaves stored in the master (⇒ slave pro-
file). If the permanent configuration differs from the ⇒ actual configuration, there
is a configuration error.
Permanent parameter
The parameter stored in the master that are sent to the slave after start-up of the
master in the ⇒ activation phase.
Configuration mode
During the configuration mode the master exchanges data with all connected
slaves, no matter which of the slaves are projected. In this mode it is possible to
commission a system without being obliged to configure it before.
See also ⇒ protected mode.
Single slave
Compared to an ⇒ A/B slave a single slave can only be addressed from the ad-
dress 1 to 31; the fourth data output bit can be used. All slaves of the older speci-
fication 2.0 are single slaves.
There are also slaves fulfilling the new specification 2.1 that are single slaves, e.g.
the newer 16-bit slaves.
Slave profil
The configuration data of a slave consisting of:
⇒ IO code, ⇒ ID code, ⇒ extended ID1 code, ⇒ extended ID2 code.
The slave profile is to differentiate between the different slave categories. It is
specified by the AS-i Association and preset by the slave manufacturer.
AS-i 2.0 slaves do not have extended ID1 and ID2 codes. In this case an AS-i mas-
ter 2.1 enters "F" the extended ID1 and the extended ID2 code.
Subject to reasonable modifications due to technical advances.
