AS-i 3.0 PROFIBUS Gateway with integrated Safety Monitor
Glossary: As-i terms
ID2 Code, extended ID2 code
The ID2 code is set by the slave manufacturer and cannot be changed. The AS-i
Association determines the ID2 codes, which are assigned for a particular class
of slaves. For example, all 2-channel 16 bit input slaves having an S-16 bit code
use ID2 code “D”. Since this code was not introduced until AS-i Specification 2.1,
it is also referred to as extended ID2 code.
Current configuration
The configuration data of all slaves detected by the master. The configuration
data of a slave, the
⇒ slave profile, consists of:
⇒ IO code, ⇒ ID code, ⇒ extended ID1code , ⇒ extended ID2 code.
Current parameter
The AS-i parameter that have most recently been sent to the AS-i slave, as op-
posed to
⇒ permanent parameters.
Configuration Error/Config Error
An configuration error is displayed if the target and the current configuration of
the connected slaves do not match. A configuration error could be due to the fol-
lowing:
Missing slave:A slave entered in the
⇒ LPS is not available
Wrong type of slave:The
⇒ slave profile of the connected slave does not comply
with the configuration.
Unknown slave: A connected slave is not entered in the
⇒ LPS.
LAS - List of Activated Slaves
The master exchanges I/O data with the slaves entered in the LAS. In protected
mode only the detected slaves (
⇒
LDS) that are expected by the master and are
entered in the
⇒
LPS are activated. In configuration mode all slaves entered in
the
⇒
LDS are activated.
LDS - List of Detected Slaves
If the master was able to read the
⇒
slave profile, the slave is entered in the LDS.
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.
LPS - List of Projected Slaves
The list of projected slaves includes all slaves expected by the master. When sav-
ing the current configuration all entries in the
⇒
LDS are stored in the LPS (ex-
cept for a slave with address 0).
