MITSUBISHI ELECTRIC
2.2.8 Configuration
Configuration of the I/O Modules
The configuration of the node is performed in accordance with the physical requirements of the head
station and I/O modules.
The head station or the process data channel is to be configured on the first slot. The other slots are
configured in accordance with the physical requirements of the I/O modules. Here only I/O modules
with process data are relevant. The supply modules, bus internal system supply module and the bus
end module are to be ignored for the configuration because they do not provide any process data.
One or two modules are entered in the hardware catalogue for each I/O module.
The module appear as "name/ID number/type/specifications", for example:
STL-DO4/51205045/4DO/24V/0.5 A.
In the hardware catalogue of GX Configurator-DP you will find the entries *STL-DO4 and *STL-RO2.
When using these denominations the head station adds the binary information of the current module
in a byte which was previously opened with a STL-D04 respectively a STL-RO2. The use of "*" is only
permitted when the number of outputs is less than or equal to the remaining bits in the previously
opened byte. The binary I/O modules combined in a byte can be arranged at separate locations, i.e.
binary I/O modules with a different signal type or also byte orientated I/O modules can be connected
between.
In order to be able to individually arrange the scope of connected periphery units independent of the
control program, it is possible to parameterize I/O modules in the configuration table as "not
plugged". In this manner process data still present is filtered for the individual module and not trans-
ferred on the Profibus DP to and read by the periphery units.
GSD Files
Under Profibus DP the features of the modules are defined by the manufacturers in the form of a GSD
file (General Station Description).
Structure, content and coding of this unit main data are standardized and made available to the user
allowing to project optional DP slaves using the project units of various manufacturers.
The GSD file is read by the configuration software and the corresponding settings are transmitted. For
the necessary inputs and handling steps please refer to user manual of the FX Configurator DP or GX
Configurator DP.
The GSD files for the STlite series can be downloaded from the following web-site:
