The PROFIBUS Parameter User Interface allows the user to set operational
parameters for the communication between the PROFIBUS Master and the
GRT1-PRT. The User Interface provides entries to set
• the device address (i.e. defining it for communication)
• the PROFIBUS group allocation for the GRT1-PRT.
• the FINS fragment length, used in acyclic communication.
• Specific PROFIBUS Master Unit behaviour with respect to this slave
device.
The I/O Configuration User Interface allows the user to define the configura-
tion of SmartSlice I/O Units attached to the PROFIBUS Communication Unit.
It also allows the user to make parameter settings for individual SmartSlice
I/O Units.
The I/O Configuration is used by the PROFIBUS Master Unit when mapping
the I/O data of individual SmartSlice I/O Units on to the PLC memory areas. It
is also sent by the PROFIBUS Master Unit to the GRT1-PRT for verification
when establishing communication. The I/O Configuration sent by the Master
Unit must match the physical configuration attached to the GRT1-PRT
PROFIBUS Communication Unit, in order to proceed with I/O data exchange.
The Monitoring User Interfaces allows the user to read information from indi-
vidual SmartSlice I/O Units. It also provides a means to read the Error Log of
the GRT1-PRT PROFIBUS Communication Unit.
The GSD file concept is the older, and consequently more widely used means
of configuration. The GSD file for the GRT1-PRT is a text based file, which
contains all options required to configure a PROFIBUS Master Unit. The file
can be loaded by the configuration software of the Master Units, which will
then present the information to the user to allow the appropriate selections to
be made.
The drawback of the GSD file is that- unlike the GRT1-PRT DTM - it only pro-
vides setting options for PROFIBUS DP and PROFIBUS DP-V1. The GSD file
does not provide the means to initiate parameter data transfer via PROFIBUS
DP-V1 Class 2 messages. These have to be programmed in the Master Unit it
self.
The GSD file for GRT1-PRT can be used to configure most third-party Master
Units. The GRT1-PRT GSD file contains all the necessary parameters to
allow the user to configure the Master Unit for I/O data exchange.
1. The GRT1-PRT DTM can also be used in third-party configuration soft-
ware provided that this software supports the FDT/DTM concept.
2. With the Cx-Profibus FDT Container OMRON also provides a Generic
Slave DTM, an FDT/DTM interface between the FDT Container program
and GSD files. Alternatively, this DTM can be used to setup a Master Unit,
using the GRT1-PRT GSD file. This Generic Slave DTM however, does
not provide the means to initiate PROFIBUS DP-V1 messages.
After setting up the configuration, it must be downloaded to the PROFIBUS
Master Unit. The download process depends on the Master Unit used.
