Because of the COVID19 issue, people are ore obsessed with cleaning. Recently , we had a problem on a machine and traced it back to an operator cleaning a touch panel changed a setting with out knowing it. These particular HMI's already had a function programmed for cleaning the panel. The operator didn't know this function existed and so they didn't use it. These were setup on Siemens Comfort panels. The operators were trained and that hurdle has been cleared.
We have other model HMI's throughout our plant and I am looking to implement a similar "clean screen" function on them. My first one will be a C-More EA9 15" panel and Contrologix PLC.
I am attaching the logic I will use to do this. I would like someone to look at it and let me know if this approach will work.
I am open to suggestions and improvement on the logic as I have very many to do.
This ability to clean the screens and not upset our processes is important and gives the operators a small measure of comfort during these trying times. We are deemed an essential business and need to keep running.
