I am working with a power flex 753 Device net and have been forcing DO output blocks for start and stops to test if I can talk to the drive. Everything was working out great. However something happened where I started the drive and went to attempt to stop the drive and it stopped, but i cannot get the 1 to leave the out put on the DO block and start the drive now. Everything was working great now I try to turn the output off and I get this error: Field:CV (458763) FB_INVALIDMODEFORWRITE, Function block is in an invalid mode for write operation. Absolutely not sure what I have done to randomly get this error.
