Question-
Say I have 8 digital INPUTS to my PLC, any of which may be asserted HIGH for a few seconds, all these inputs "OR'd", currently, to produce a 1 second OUTPUT pulse, to show general activity in my plant. Say further that activity is fairly quiet and the same input is the ONLY input asserting itself multiple times in a row...
I'd like to somehow inhibit any input from causing an output pulse IF it was the LAST input to have created an output pulse.... I.e., I don't want any one input to cause an output if it isn't preceded by an input other than itself... Once any other input causes an output, the inhibited input can rejoin the fun...
Any simple ideas?

Many thanks!
