Abstract: A system and method for detecting integrity of a position for a mover in an independent cart system, includes receiving multiple first position feedback signals at a first processing core and receiving multiple second position feedback signals at a second processing core. Each of the first and second position feedback signals are generated by first and second position sensors, respectively, by detecting a magnet array mounted on the mover. A first value of the position of the mover is generated with the first processing core responsive to the first position feedback signals, and a second value of the position of the mover is generated with the second processing core responsive to the second position feedback signals. The first and second values of the position of the mover are compared with either the first or second processing core to verify operation of the first and second position sensors.
