Assign parameters
To assign parameters is to pass slave parameters from the master to the slave.
B
Baud rate
Rate at which data are transmitted; specifies the number of bits transmitted
per second (baud rate = bit rate).
Bit time
The bit time (T
value of the baud rate: T
C
Configure
Configure means performing the different settings for individual modules in a
Distributed I/O System.
Consistent data
Data which have related contents and must not be separated are known as
consistent data.
The data of an ASi slave must always be treated consistently, the data must
not be corrupted by being read out at different times.
Control command
A DP master can send commands simultaneously to a DP slave, a group of
DP slaves or to all DP slaves to synchronize the DP slave stations.
By means of the
to synchronize DP slave stations by event driving.
D
Diagnostics
Diagnostics comprises detection, isolation, classification, display and the
ongoing evaluation of errors, malfunctions and messages.
Diagnostics features monitoring functions which run automatically during
system operation. In this way higher availability of the system is achieved as
a result of shorter commissioning times and down times.
Within the distributed I/O, there are various diagnostic possibilities – ranging
from the overview as to which DP Slave has reported a diagnosis to the mon-
itoring of individual inputs and outputs.
