We have a load of DT021 display terminals still in use on our lines. They are connected via RS232 to Omron C60K PLC's. All they do is display a fault code based on the value of DM0009 in the relative PLC they are connected to and also a machine speed from another data memory. A couple of these displays have lost their program? and display japanese on the screen.

Does anyone know where I can get hold of the software to re-program these ageing screens?

Any help appreciated. Thanks.

Fantastic! Thanks.

I may have just hit another problem, I don't think I have a copy of the program for the screen, is there a way to download it from a good working screen or will I have to start from scratch?

The answer is not in the manual that was in Jay's response?

Hi, Still not getting to grips with the old DOS software. I have found another program called Sysmate DT021 R/W which on the face of it looks like it should be able to save from a good working screen and load in to a none working screen.
I have no documentation for this though and get an error 69 when trying to save from a screen. This is all assuming that I am using the correct cable and dip switch settings on the screen.

Any more info or advice appreciated, Thanks.
