Strange Program

4 posts in this topic

I have a direct logic 06 plc and once in a while the program, which is normally 130ish lines, will add around 1000 extra lines. When this happens my machine will not run. Does any one have a clue what is causing this or how to fix it?

You mean the program in the PLC is changing? If so, then it is probably from dirty power, or the PLC's internal power supply is bad.

Also update your firmware. As jawoltuis said, this is a symptom of poor power. There have been firmware updates that help with similar issues.
