Download GSD Files
Determines whether a Full Upload or Generic Upload can be performed from the
downloaded configuration.
If you set this parameter to False (default), GSD files are not downloaded to the PLC.
Subsequent upload operations are Generic.
If set to True, the GSD files required by the network configuration are sent to the PLC.
Subsequent upload operations are Full uploads.
Full Upload -- A full upload of a hardware configuration containing a IC693CPU366 has
the following characteristics:
Occurs if Download GSD Files is set to True on download.
You have full configuration capability, including adding slaves and adding new
modules to existing slaves.
The Toolchest is populated with GSD files from the uploaded configuration,
allowing you to add more of an existing slave to the configuration.
Download/upload of text fields, such as descriptions, is controlled by the
Download Names/Descriptions parameter.
Generic Upload -- A generic upload of a hardware configuration containing a
IC693CPU366 has the following characteristics:
Occurs if Download GSD Files is set to False (default) on download.
If the project is uploaded from the PLC and the GSD files are in the Toolchest,
the network is rebuilt. If the GSD files that were used to build the network are
not present in the Toolchest, the network is rebuilt but new modules cannot be
added to the slaves.
Existing slaves for which there is no GSD file in the Toolchest are made
generic. You cannot add or remove modules under the generic slave. The
following operations can be performed on a generic slave:
- Change its station number.
- Edit its parameters in hex mode.
- Delete the slave.
New, fully functioning slaves can be added from GSD files in the Toolchest.
Note: Downloading GSD files may use too much memory in the PLC. It is recommended that this parameter remain
set to False (default).
