Secondly, load the HMI programming software and adjust the speed 'Settings' to
2400 baud in the 'Transfer \ Project' window before starting the transfer.
NOTE: After each successful transfer the call must be terminated and redialled at
9600 baud before normal transparent mode to the PLC can be resumed.
CAUTIONARY NOTE:
At the time of writing. it is only possible to communicate with the E range and certain
versions of the MAC range of HMI's, using either method 1 or 2.
3.3.5 Transferring files from/to the HMI
It is also possible to download files held in the E HMI, for example, "Trends",
"Recipes" and "Alarm Lists". To do this requires the HMI to be dialled from the
Windows HMI Tools program "Filetran".
Firstly, enter your telephone numbers in the Connections list by selecting 'Edit',
under 'Options\Comm Settings'.
Then check that the communication is set to
9600,8,N,1.
a) Method 1 (preferred):
Using two Mitsubishi A2S/DIN/DESK MODEMs at both ends.
To dial your chosen telephone number click 'Connect' and wait for the Files to be
displayed before selecting the files to receive or send..
To "Hang-up", click on the 'Close' button and the modems will return to their normal
"command mode" state.
b) Method 2:
Dialling from another manufacturers make of modems connected at the PC end.
Firstly, make sure that the RS232 port in the HMI is set to 9600,8,N,1 then dial as
described in method 1, above.
NOTE:
The RS232 port in the HMI will need to be changed back to the FX or AnS format
every time it is required to program a PLC through the transparent mode.
3.3.6 Communicating with other makes of PLC controllers
Because the purpose of the Modems' on-board intelligence is to communicate
specifically with the Mitsubishi range of PLC's there may be some difficulty in
transferring data between other makes. Until a local protocol has been written for the
device being connected, setting another code will confuse the modem and it will
incorrectly convert the serial format.
To allow the A2S type modem to be used for non-Mitsubishi equipment, for example
On-line Maintenance operation, it will be necessary to set the remote A2S Modem
into the special transparent protocol, as follows:
