HSA
Highest Station Address
The highest address to which the master will look for new masters. This is done
with the FDL Status message. It has nothing to do with the configured slaves!
Default value is 126, but the end user can decrease it to a lower value. We
recommend leaving it on 126 in order to display not configured slaves in the Live
List. This value does not influence the I/O cycle time of the network.
Hub
A Hub refreshes a signal and passes the information on to all nodes which are
connected to the Hub. Data frames which were received on one port are
transferred to all the other ports (chicken foot topology).
Ident Number
The primary slave device identification is an Ident Number. This is a unique 16
bits number assigned by the PNO. It is stored within the device and defined in
the corresponding GSD file. In addition it is part of the GSD file name. At runtime
the Ident Number is used within the;
•
Set slave address procedure
•
Parameterization telegram (byte 5 + 6)
•
Standard part of a diagnosis message (byte 5 + 6)
The Ident Number can be retrieved from a device. Its main purpose is to make
sure that a GSD file and configuration/parameterization data between master
class 1 and its slave are matching.
LED
Light Emitting Diode
Indicators on devices to inform he user of its status.
Live List
The Live List is a matrix that lists all the available devices. It is directly visible
which devices are ‘troublemakers’. With different background colours the status
of the devices is displayed. The Live List can also generate the product name of
the devices when a diagnostic message is captured (synchronized with the GSD
library).
Module
A card that can be inserted in the backplane of ComBricks.
Examples of modules: repeaters, DP slaves or I/O cards.
MPI
Multiple Protocol Interface.
Protocol defined by Siemens which uses the layer 1 and 2 of PROFIBUS (FDL).
OE
See ProfiTrace OE.
PA
See PROFIBUS PA.
PB
PROFIBUS.
