A special power supply combining a DC supply and a decoupling circuit needed
in an AS-Interface network.
Time to send one bit on the AS-Interface line.
The value of the I/O configuration and the identification code of a specific slave.
The image of the configuration data of all slaves, stored in the AS-Interface
master.
Period of time when the master sends values of the output data image to the
slaves and receives input data from the slaves.
A part of the AS-Interface power supply for decoupling the DC source and for
conditioning the physical data transmission within the AS-Interface network.
Period of time when the execution control of the master tries to find all slaves
connected and operating. All slaves found are listed in the list of detected slaves.
Master function that controls the message exchange and provides several
functions to the host interface.
The user of the master. Users may be, for example, a programmable logic
controller, a personal computer, a gateway, or a human operator.
The logical interface between the master and the host.
Set of four bits which defines the direction of data flow at the slave I/O ports.
Set of four bits which defines the type of slave for a given I/O-configuration.
Input data stored in the master, received from the slaves.
A list of all slaves at the AS-Interface line that are activated and capable to
communicate properly with the master. The list is available in the master.
A list of all slaves actually detected by the master. The list is available in the
master.
A list of all configured slaves of the interface system as the target configuration.
The list is available in the master and It includes the configuration data of all
configured slaves.
Control unit on the AS-Interface line that communicates serially with the slaves.
The time between the last bit of a master request and the first bit of the slave
response at the master.
Message sent from the master to a single slave.
Data that remain unchanged after power interruption.
Address of the AS-Interface slave different from the zero address.
Output data stored in the master to be transferred to the AS-Interface slaves.
Parameters (sets of 4 bits) that define the functionality of all the different slaves in
the AS-Interface network.
A stand alone device or part of another device that provides an interface to the
AS-Interface line and communicates with the master.
The time between the last bit of a slave response and the start of sending the first
bit of the next master request, measured at the master ports.
Answer that is sent to the master by the slave after a master request has been
received and processed without error.
A transaction comprises a master request and a slave response.
Master function that controls the data transmission, transmission pauses and
retransmissions in case of failures (e.g., transmission failures, missing response
from the slave, invalid response received, ...)
Special address reserved for the online assignment of a new address to an AS-
Interface slave.
