T64H

Hi, I'm not able to connect to T64H. Any idea about USB to RS232 cable.?

Do you mean you don't have an USB to RS232 adapter and need to purchase one? We do supply a USB to RS232 adapter as follow:

What I meant was, I have USB to RS232 cable but I still can't get connected. Perhaps a standard off-the -shelve cable such as these are not suitable for plc applications? Thanks.

Are you using the WinTRiLOGI version 3.5 software? T64H-Relay default baud rate is 9600bps, 8 data bits, 1 stop bit and no parity. You need to go to the Controller menu and select Serial Port Setup and the select the correct COM port. Test communication with the "IR*" command.

Your RS232 port must have a +10V on its pin 4 that goes to the PLC to power its opto-isolated RS232 interface. If this voltage is missing then you will not be able to communicate with it.

Thanks for your quick respond. Yes I'm using WinTRiLOGI version 3.52. From the pull-down Controller menu, I use Detect ID since I'm connected to one plc but still could not get connected. About the voltage presence at pin 4, how do I check them? Are there any particular brand of USB to RS232 recomended to work with T64H?

for discussion on USB to RS232 adapter.

Have you previously connected to this PLC before using a laptop with built-in RS232 port? If so, then it is likely an incompatible USB-RS232 adapter.

Thanks mate..The link you provide helps me to understand about the RS232 and I'm connected to the plc. It was both Com port setting and USB to RS232 converter.

The next thing is, I'm not able to retrieve programs in the plc using "Open matching source file" from "Controller" menu. What I did was, I do "Program transfer to plc" using demo program. It says program transfer complete. Using new Untittled page, I tried to retrieve back the program and I cant. Changing the filename to the same one as I have uploaded earlier and I still cant. Both occassion it prompt filename does not exist. Hope you can help on that. Thanks.

It is not possible to retrieve downloaded program from the PLC using WinTRiLOGI software back to the PC. This is to protect OEM users so that there downloaded program will not be easily copied.

The "open matching source file" menu item is only used to match the file name of the previously downloaded program from the PC with that on the PC's hard drive. If you don't have the program file stored on your hard drive then it will not be able to open a "matching" file name.

Oops..that's a bit of a problem. I install that progam about 10 years ago using Dos version and RS 232 cable. Since then, I've connected to the plc 4 or 5 times to  modifiy the program, still using Dos version. Now I don't have the Dos version anymore.
- Can I get the Dos version of TriLOGI
- would I be able to retrieve my old program.
Thanks.

We no longer support the DOS version since they would not work on your PC which is most likely running windows XP, Vista or Windows 7.
