4. Setup
4.1 GSD File
T
he operation of the equipment described in this manual requires a GSD file in GSDML format.
GSDML-Vx.x-Murrelektronik-MVK_MPNIO-JJJJMMTT.xml
I
mport the GSD file to the corresponding configuration tool before starting up the device.
The GSD file can be downloaded from the Murrelektronik website under "Service >> Technical Data:

4.2 Configuration with S7 Hardware Manager
T
his chapter explains the HW configuration as an example (hardware setup software of the Siemens
Simatic S7 Manager) to show how a MVK-MPNIO is configured and parameterized.
4.2.1 General Information
A PR
OFINET device must be configured in order to define the quantity of I/O data and to re-
serve addresses in the controller.
T
he MVK-MPNIO is a compact device in the physical sense. In the PNIO system, however, it is
considered a modular system. This modular system consists of a "virtual" head module, which is
followed by "virtual" user data, and "virtual" diagnostic modules.
F
irst, the head module is added to the virtual bus, similar to a modular set. Head modules al-
ways have data length zero and are used to identify and parameterize the module. They are re-
lated to the Part No. of the corresponding MVK-MPNIO.
Each head module is automatically followed by an energy supply module on socket 1. The di-
agnostic is reported to the power supply units via this module.
T
he user data modules can then be connected in any required order. Each user data module
has a data length of one byte. An individual address can be assigned to each of the user data
modules in the PLC process image.
MV
K-MPNIO not only offers the possibility of transferring diagnostic information in acyclic diag-
nostic telegrams, it can also include this information in the cyclic data exchange as well as the
user data. This is performed using the diagnostic modules.
T
he advantages are:
A
ccess to the diagnostic information is given in the same way, independently of the PN
controller used.
The diagnostic information is available in the process image and can be evaluated quickly
and easily.
No need for inconvenient operation with special diagnostic function blocks.
Only as much memory in the I/O range is used as is required in the process image of the
c
ontroller.
