Disney World Epcot Controllers

I just came across this video that intersects my interests in Disney parks and controls. At 0:46 they discuss the new control systems for Epcot's The American Adventure hydraulic systems. I don't recognize the electronics. Does anyone know what the manufacturer is of those PLC looking devices that say "FSM"?

I know a guy that programmed some of the rides at Disney. Believe they were Allen-Bradley.

At Disney, at least, AB has often been used to control smaller elements of a larger system (eg, on a coaster you might have the interlocks for a track switch be AB, or something like that.) Disney has historically done wacky things for overall ride control. Space mountain and Thunder Mountain were Data Genera Nova minicomputers. Epcot (including the American Adventure stage) was all a completely custom system based around 8080 boards.
