Downloading Files to the Bridge
Before initiating your first download:
H Install an HTTP server on the host machine and configure it as described in
Section 5.1.
H Copy the program DWNLD.EXE from the host software diskette to the HTTP
cgi--bin directory you have configured on the host machine:
\\cgi-bin
5.3.1 Download Overview
You can download a new version of the bridge’s application SGATE.BIN file or
mapping RTE.TXT file to the bridge. To download a file, write the host URL and
filename as data to register 8 in the bridge. After the download, the status of the
download will be stored in the file MODICON.LOG in the host cgi--bin directory.
SGATE.BIN
When the download is complete and the bridge is restarted, the bridge will copy
SGATE.BIN to its application program SGATE.EXE. It will begin running this as its
new application.
RTE.TXT
The bridge’s mapping tables are stored within the bridge in the file RTE.CFG.
Before downloading new mapping, you must place it in a file named RTE.TXT.
If you have previously uploaded RTE.CFG, the file’s contents are appended into
the MODICON.LOG file in your cgi--bin directory. You can copy those RTE.CFG
contents from MODICON.LOG and paste them into an RTE.TXT file. Then you
can download the RTE.TXT.
The RTE.TXT download will write a new RTE.CFG file in the bridge. When the
download is complete and the bridge is restarted, the bridge will use this file’s
contents as its new mapping tables between TCP and Modbus Plus.
5.3.2 Initiating a Download
To initiate a download:
H Put the file to be downloaded (SGATE.BIN or RTE.TXT) into the
of the host machine.
