Is there any Free software for these I need to upload a program and put in another unit I have the output light turning off but the power never goes away on relay output, thinking the relay welded.
I am downloading Lite version after registering at Omron, (Taking Forever) are there proprietary cables needed The unit in question is connected to an Omron touch screen through an RS232C adapter I believe.
Here is a tutorial link for using the old SysWin software. You might find it useful or at least informative. I would recommend that you pay particular attention to the whole page, especially Appendix E on the lower right side of that webpage. http://www.mikroe.com/old/books/plcbook/plcbook.htm
