Module n Type / Module n Length
The PS69-DPS PROFIBUS-DP Slave offers a flexible, modular composition of its
I/O data. This means that parts of the input and output image can be viewed as
single modules. The master can put the different modules from the PROFIBUS-
DP Slave to different locations in its I/O area. The individual configured modules
are mapped linearly in the I/O area of the Slave module. It is possible to
configure up to 24 I/O modules. A module is defined by a Module Type and its
Module Length:

Note: Please notice the definition of Input/Output modules and do not confuse them with the input
and output area of the module in the controller memory map. PROFIBUS gives a clear definition of
Inputs/Outputs. Inputs and Outputs modules are always defined from viewpoint of the PROFIBUS
master. If you configure an Output module you will see this in the input area of the communication
module, because the input area of the controller memory map is the output area from point of view
of a PROFIBUS master. The same applies to an Input module. If you define an Input module it is
mapped in the output area of the controller memory map, because the output area is the input area
from viewpoint of a PROFIBUS master.
The projects on the DVD can also be used as an example for a module
configuration by the controller application. You only have to set the parameter
"ForceUserConfiguration" from 0 to 1 in the configuration array. In chapter
"RSLOGIX SAMPLE PROGRAM" later in this manual explains the predefined
configuration parameter of the sample project.
