Multiple points of order

[Law]

Dear all,

I'm trying to figure out what is meant here by "Multiple points of order". It's from a car wash commander controllers users manual.

"Also features such as Non-Sequential Stack Up and Multiple points of order can be obtained by adding IPB-34 INTELLIGENT PUSHBUTTON STATIONS. A maximum of 5 IPB- 34's (4 Points of Order plus 1 Keypad) may be tied in."

Thanks in advance for your help !

In a tunnel instance I would guess it means you could use 4 IPB-34 (12 button) push button stations and 1 keypad to control different functions along the tunnel without going back to the main controller. Plugged in in any order.

Thank you very much for your time and answer. It makes more sense.
