4.15 Uploading and Downloading
To upload or download a configuration file, the 905G must be connected to the PC via a
RS232 cable. For Modbus/DF1 units, the host device must be disconnected, even if it is
connected to the RS485 port. Other units do not need to disconnect the data bus. When the
PC is connected, put the 905G into configuration mode by pressing the small pushbutton
switch in the end plate of the module for 5 seconds, until the ACT LED starts flashing.
In configuration mode, the 905G will stop its normal functions.
Make sure the correct
communications port is
selected on the PC - if
necessary, change the
selection from the
Utilities menu.
Connect the PC to the
module using the
configuration cable.
The configuration may
be programmed into a
905G, or a
configuration may be
loaded from a 905G.
After programming or
loading is complete,
disconnect the PC from
the 905G. Reset the
905G by removing
power and re-
connecting power. The
905G will start up
normally and the OK led will be on. The serial port will have its original set-up.
4.15.1 Loading from a 905G
If you load a configuration from a 905G into a “blank” or new project, then the program will
not be able to display the mappings from remote modules (as the program does not know
what the remote modules are). You will get a warning message like this:
If you open the archived project first, and load into the archived project, then all mappings
will display as normal - any mappings to/from the 905G will be over-written on the PC
display by the loading process.
