regarding the communication cable

[chitra]

i am using T22H for the first time. do we need to use only DB9 cable RS232 . i did not have rs232 socket in my laptop. so i used a rs232 to usb connector to connect to the PLC and i used internet trilogi ver 5.1 . but i get a pop up message stating "no response from PLC"
so am i using the correct interface (usb to rs232) ?
Or is it some other mistake?
Please help.

T22H can only be programmed using WinTRiLOGI version 3.5x or the DOS version TRiLOGI 3.3.

Where did you get your copy of internet TRiLOGI version 5.1? This is a very old version and only works for the T100MD+ PLC and will not work with T22H-npn. If you have downloaded the educational version from our website it won't work either.

Yes, T22H-npn is still in production even though it is already more than 15 years old design, but is still popular among some users for its simplicity and reliability. We will keep producing them as long as there are still OEM users who rely on the model and is not interested in upgrading to the more capable models.

Uploading of PLC program is not supported by WinTriLOGI. OEM does not like user to be able to upload program from the PLC since other people can copy the program easily.

In your case you may need the original source file. If you can't find, try to swap the H2044 IC (8-pin) between the new PLC and the old PLC. If the H2044 is good or the program is not corrupted then the new PLC will be running the original program in the old PLC. If this doesn't work then you may need to rewrite the program.
