configuration data (PCD) and independent of LPS.
A full list of the CQM1-ARM21's available functions is given in Appendix A,
AS-Interface PICS.
To allow an uncomplicated usage in standard applications, AS-Interface
defines "profiles" for the slaves. In general a slave does not have a fixed
meaning assigned to the I/O data and the parameter values, i.e., the
specifications for the communication part do not restrict the usage of a slave
to specific applications. However, it is the most important issue of the slave
profiles to restrict the use of the data and parameter values for the most
common applications, and to assign specific semantics to them.
In addition to the AS-Interface specifications, a profile contains all the
additional definitions and restrictions needed for a slave in a specified
application. The slave profile is independent of the vendor of the actuator,
sensor, or other devices and elements. Thus, the profiles should help to
increase the interchangeability of actuators and sensors.
A slave profile has a well defined and fixed:
- I/O configuration (I/O code) with well defined semantics for the I/O data
and parameter values,
- identification code (ID code),
- definition of semantics of the levels high or low of the I/O data and
parameters,
- list of minimum requirements on the physical realisation.
The ID code of the slave is used to distinguish between different slave
profiles with the same I/O code. It is fixed to the slave during the assembling
of the slave and is stored non-volatile and irreversible.
Defined slave profiles exist for:
- I/O=X ID=0
- I/O=0 ID=1
- I/O=1 ID=1
- I/O=7 ID=1
- I/O=7 ID=2
- I/O=B ID=1
- I/O=D ID=1
Virgin slave chips, before assembly at the manufacturer, have no particular
configuration. They carry the I/O code = F
