AS-Interface
Glossary
Inclusion phase
The AS-i master sends a command to an available slave address to detect new
slaves. If no reply is received, it immediately begins with the next data exchange
phase.
I/O code
The first digit of the slave profile, which indicates how many in- and outputs the
slave has. A 4I/4O slave has for example a “7”, and a slave with 4 digital inputs a
"0".
LPF - List of Peripheral Faults
The list of peripheral faults was introduced with specification 2.1. This list includes
an entry for each slave that signals a
⇒
peripheral fault.
Master configuration
Released configuration, without code sequences. The safety unit cannot turn on
the outputs, but as soon as the code sequences are learned, the device is usable.
Such a master configuration can for example be used in serial production ma-
chine building for loading the safety program, whereby the configuration is creat-
ed in the design and the code sequences taught on the physical machine.
Offline phase
In offline phase there is no communication on AS-i.
Password
Security code for a (security) configuration, is required for releasing a configura-
tion or activating a changed configuration. The password is a string of 4 … 8 al-
phanumeric characters. It is stored in the configuration.
Peripheral fault
Depending on the slave, an overflow, an overload on the sensor supply, or some
other fault affecting the slave peripheral can be displayed.
PIN
A security code is required for teaching code sequences. The PIN is a 4-digit dec-
imal number.
The PIN does not authorize for activating a safety configuration.
The PIN is stored in the EEPROM of the unprotected device section as well as in
the unprotected area of the chip card, and is therefore sent to a new device when
the chip card is replaced. When resetting to factory defaults, the PIN is set to
0000.
