Uploading and Downloading Files
53
H In the Modbus command to the bridge, perform a register write to register 8
in the bridge. Write the host URL as data into that register.
The URL can be in the absolute IP address form:
205.167.7.0/<filename>
or it can be in the form:
//<host_name/domain/<filename>
where <filename> is the name of the file to be downloaded (SGATE.BIN
or RTE.CFG). Note that you specify RTE.CFG here, not RTE.TXT.
H When the download is complete, the download status will be contained in the
MODICON.LOG file:
//<host_machine>/<http_root_directory>/cgi-bin/modicon.log
The new contents will be appended to an existing MODICON.LOG file.
Note that the MODICON.LOG file can grow large as new data is appended.
It is the user’s responsibility to delete or edit the file as required.
H The bridge will automatically begin using the new downloaded configuration.
5.3.3 Download Example
Here is an example of the contents of a message to download the file RTE.TXT
from the host path: //username.modicon.com/WebShare/wwwroot.
The following contents would be written into register 8 in the bridge:
//username.modicon.com/WebShare/wwwroot/rte.cfg
