1-4 CX-Profibus Configurator
1-4-1 CX-Profibus Features
CX-Profibus The PROFIBUS-DP Master Unit requires a configuration before it can
exchange I/O data with the Slave stations. For this purpose OMRON provides
the CX-Profibus Configuration program, which runs under Microsoft Win-
dows™ NT 4.0, Windows™ 2000 or Windows™ XP
Together with the CX-Profibus Container application, OMRON provides two
DTM COM Objects:
• A DTM to configure the CS1W-PRM21 / CJ1W-PRM21
• A DTM to allow the handling of classic GSD files in CX-Profibus
The following presents a quick overview of the functions.
CX-Profibus FDT
Container application CX-Profibus provides an FDT environment in which DTMs can be executed.
The main function of CX-Profibus is to facilitate the DTMs and the data
exchange between them. It provides:
• Network setup functions: A tree view shows the relations between the
DTMs, i.e. the relation between the Master and Slave devices.
• Device Catalogue functions: A Device Catalogue containing the installed
DTMs is maintained, to which the user can add new DTMs or delete
them. Device DTMs can be added to the network from this Catalogue.
• Project maintenance functions: CX-Profibus provides the functions to cre-
ate, save and open project files. It also facilitates user access control,
allowing the limitation of use to authorized personnel only, using pass-
word protection.
• Additional functions: CX-Profibus provides additional functions like print-
ing, error logging, FDT Communication logging and help files.
CS1W-PRM21/CJ1-PRM21
DTM The CS1W-PRM21/CJ1W-PRM21 DTM consists of three parts:
• The Settings DTM, which handles the configuration for the PROFIBUS-
DP Master Unit. This includes the bus parameters settings, the I/O data
mappings and Master specific settings. The Settings DTM provides its
own User Interface.
• The Monitoring DTM, which handles the status monitoring and control
over the PROFIBUS-DP Master unit, when it is on-line and communicat-
ing over the PROFIBUS network. It provides its own User interface to
read out Master status flags and Error log, as well as Slave status flags
and the Slave diagnostics messages received by the Unit. It also allows
the user to send Global_Control messages over the network and to
change the PROFIBUS-DP Master Unit’s mode on the PROFIBUS net-
work.
• The communication DTM, which provides the interface between the two
DTMs mentioned above and CX-Server. Cox-Server, which is provided
with the CX-Profibus packages is the driver providing communication
between the PC and the PLC CPU.
Generic Slave DTM The Generic Slave DTM allows the handling of classic GSD files of up to GSD
revision 3 within CX-Profibus. Upon allocating a Slave station, for which only
a GSD file is available to a Master Unit in the network, this DTM will be
invoked. This DTM also consists of two parts:
• The Settings DTM will provide the user interface to display the device’s
information and the selectable values, as defined in the GSD. After mak-
ing the necessary configuration settings, these will be transferred to the
Master DTM automatically.
