I would like to get input/suggestions for displaying alarms, messages and faults. I'm really looking for any references, guidelines, books, etc. that may describe methods for creating machine failure messages from the PLC to HMI. I have done this many times, but know that my method(s) may or may not be better than anyone elses. I worked for an OEM company that supplied the automotive industry with wheel alignment machines and typically Ford, Chrysler, etc. would have a specification book on what and how alarms were displayed and acknowledged. The
spec's were supposed to be corporate-wide, but in reality each plant was different. Sometimes we would just display messages, sometimes if
there was a fault, the machine was not allowed to continue to the next step until the fault was corrected. I am doing research on this subject and will probably be including this topic in my book for our company. Any input is greatly appreciated!
