Offset Data Size Alignment Mask Divisor
Byte 6 16bit (unsigned) Normal FFFF 100
Resulting channel: (0xCC8A masked with 0x0FFF) / 100 = 523 so channel is
clamped to 255
Typical CAN input channel application
A CAN message contains a 16 bit RPM value with resolution of 1 RPM.
Using a 16bit unsigned data type and a divider of 100 gives a resulting
channel with a resolution of 100 RPM. The maximum channel value of 255
will be equivalent to 25500 RPM.
The resulting channel can be used in conditions to turn outputs on when the
RPM is above or below preset limits.
