4.3 Configuration
The configuration of a Profibus DP slave is required for defining the quantity of I/O data and for
reserving the addresses in the control.
The MVK-MP is a compact device in the physical sense. In the DP system, however, it is considered a
modular system. This modular system consists of a "vitual" head module, which is followed by "virtual"
user data and "virtual" diagnostic modules.
First the head module is included in the configuration, same as in a modular set. Head modules always
have data length zero and are used to identify and parameterize the module. They are related to the
part no. of the corresponding MVK-MP. Please note that you can only add one head module, which has
always to be the first element in the configuration.
Now the user data modules can be connected to the head module in any required order. Each user data
module has a spefic data length (one or two bytes). To each of the user data module an individual
address can be assigned in the PLC's process image.
MVK-MP does not only offer the possibility of transferring diagnostic information in a DP diagnostic
telegram, it can also include this information into the cyclic data exchange same as the user data. This
is done via the diagnostic modules.
The advantages are:
 Access to the diagnostic information is given the same way, independently of the DP
master used.
 The diagnostic information is available in the process image and can quickly and easily
be evaluated.
 No inconvenient operation with special diagnostic function blocks required.
 In the process image of the control only as much memory in the I/O range is used as
necessary.
The MVK-MP uses the ID format described in IEC 61158.
4.3.1 Relation between Channel Number and Pin/Socket
By means of the channel number you can define the socket and the associated pin. Example: The
channel number is 12, this corresponds to Pin 2 (X=1) of socket no. 2 (Y=2).
Channel number = XY

X = 0
