Generic Slave Device DTM
Section 3-4
The Configuration User Interface for the Generic Slave Device DTM, contains
three tabbed windows. Above these windows the Device, the Manufacturer,
the GSD file and the Unit’s PROFIBUS ID number are displayed.
Configuration Tab
The Configuration tab contains the Device settings and the I/O Module Con-
figuration.
Device Settings The Device Settings contain the station address, i.e. the Unit’s PROFIBUS
address and the Watchdog time for the Unit. The station address is normally
set automatically by the Master DTM, when the slave DTM is added to its
tree. However, the User has the opportunity to change the address. The
changed address will be transferred to the Master DTM.
Note In case a changed address is invalid, for example if there is already another
slave device with the same new address, the Master DTM will set the number
back to its old value.
The Watchdog value is the value used by the slave device to monitor commu-
nication from the Master Unit. If no messages are sent to the slave by its Mas-
ter within the Watchdog timeout time, the slave device will stop data
exchange and switch back to the fail safe mode.
Module Configuration The I/O Module Configuration defines the I/O Data which the slave will be
exchanging with the Master Unit, when it is in data exchange mode. The
upper window in the Configuration tab contains all possible modules, which
are in the GSD file. The lower window holds all selected I/O modules.
The User has to select the modules, which are associated with the physical
configuration of the slave device. Selecting, i.e. copying the module from the
upper window of the lower window can be done in several ways.
• Double-click the left mouse button on the selected module in the upper
window.
• Select the module in the upper window and click the Insert button or
Append button. Insert will insert the module above the row selected in the
lower window. Append will add the module to the end of the selected
module list.
Note 1. The User can select multiple rows (in both windows) by simultaneously
holding the SHIFT or CTRL key on the keyboard and selecting the rows
using the left mouse button.
2. The amount of I/O modules and data which can be selected depends on
the slave device. The four rows of information above the module display
the maximum amounts as well as the selected totals.
Removing one or more selected modules from the list is done by
• double-clicking the left mouse button on the module in the lower window.
• selecting the module in the lower window and click the Remove button. In
this case selecting multiple modules is also possible.
