I would check section 4-1 through 4-2-4 of the CT021 manual - make sure you aren't writing to reserved memory locations used for configuration data of the CT021 unit.ġ) Check of the above manual to see the location of the machine switch settings. Maybe checking it too offten? Anyhow if anyone has any idea what these do or how they would change please post.ĮDIT. One thing i thought might cause this is every cycle of the program it was checking the value of an encoder connected to this card. I have added some new code, but nothing big or really even used as i had the outputs of the new rungs jumped out.
No idea on how or why these would change they should of been Output Control Mode = Range ModeĪnd/Or Counter Output Patterns = Logically Or This was there reading Output Control Mode = 0x40 No Applicable Set DataĪnd/Or Counter Output Patterns = 0圆4 No Applicable Set Data Output Control Mode and And/Or Counter Output Patterns. Clicked on parameters for that card and found two settings in red. How i found it was by going to the IO Table and Unit Set up. It happen all of a sudden after its been running the program for some time.
