Configuring the Slave Devices
Section 3-3
Example
The figure below, shows the DTM User Interface for the CJ1W-PRT21
PROFIBUS DP slave device.
The DTM Configuration User Interface displays two lists.
• The Available Modules list, which contains the I/O modules the user can
select.
• The Configured Modules list, which contains all the I/O modules selected
by the user.
Adding/Inserting I/O
Modules
To select the I/O modules, perform one of the following procedures.
• Select the I/O module that needs to be added in the Available Modules
list, and double-click it with the left mouse button. If more than one mod-
ule must be added, repeat this step for the other modules.
• Select the I/O module that needs to be added in the Available Modules
list, and press either the
Insert
or
Append
button. This method allows
selection of more than one module, by pressing either the
Shift
or the
Ctrl
key on the keyboard, while selecting the modules.
Note
1.
When pressing the
Insert
button, the selected I/O module will be inserted
above the selected module in the Configured Modules list.
2.
The selected I/O modules are sent to the slave device, in the same se-
quence as selected in the user interface. Depending on the device, the se-
quence may be checked by the slave device. If an incorrect sequence is
sent, the I/O configuration is rejected. This is for example the case with the
OMRON PRT1-COM Multiple I/O PROFIBUS DP Interface.
3.
A mandatory I/O module sequence is sometimes indicated in the GSD file,
by using non-PROFIBUS standard GSD file keywords (i.e. only interpreted
by a specific configurator). The Generic Slave DTM does not check such
keywords. In this case, refer to the manual of the specific device for details.
