User Manual PROFview XL 4 The PROFview XL Application Software
4.4.3.4 Master simulator
The PBT master simulator serves for commissioning and measuring on idle PROFIBUS plants; it can be acti-
vated/deactivated by clicking on the master simulator button. The communication with all existing PROFIBUS
stations starts immediately after activation, and all measurements can be carried out. A yellow background in
the current view symbolizes that the PBT master simulator is active.
As already described in Section 3.4.1 "Master simulator", the master simulator can only be run on an idle
plant, i.e. the master station must be disconnected from the bus, as described in that section. Only when the
PBT no longer detects level changes (bus status LED = yellow/red, differential voltage > 0.1 V) can the mas-
ter simulator be activated.
4.4.4 Status bar
The status bar can be found at the bottom of the PBT application software window (Fig. 6).
When the mouse pointer or the direction keys are moved through the menus, the left area of the status bar
describes the functions of the entries in the menu. This area also displays appropriate descriptions regarding
the effects of the buttons on the toolbar if you move the mouse pointer over these buttons.
The right-hand area comprises the trigger status icon, information regarding the PROFview XL connected,
and keyboard information. The trigger icon is lit whenever a trigger pulse is initiated at the hardware trigger
output. If a PROFview XL is connected and is in use, its serial number is displayed.
4.5 "Configure segment" view
The "Configure segment" view is displayed directly after starting the PBT application software. Here you can
make the basic settings for measuring. Fig. 7 shows a screenshot.
4.5.1 Segment
If your PROFIBUS plant consists of several segments (bus segments separated by a repeater), you can op-
tionally enter a name for the segment (max. 30 characters) in the field "Designation" to permit differentiation.
The data transfer rate you wish to use for the PROFIBUS segment to be measured can be set under "Baud
rate". You can also use the "Baud rate scan" function to let the PBT determine the baud rate automatically.
