Keith, that was sort of my point. Still a single Start button, but the similar functions of Jog/Thread can be anywhere.
We do have a few lines around here that do have multiple "Line Start" buttons, but that is the exception rather then the norm.
The reason that most lines here do not have multiple start buttons is just that on an actual start up, there are way too many things that the operators need control over, Line speeds, Pressures, Levels, etc.
All of our lines return to a zero speed setpoint on Stop, so being able to 'Start' them from anywhere would require many more duplicate controls/HMI's. Thread/Jog take care of that problem by having a slow, fixed, pre-programmed speed and conditions when engaged.
