@AN (Analog Input)

[Function]

DESCRIPTION:

@AN returns the value of an analog input as a voltage (+/-10V). Note that the @AN command is a
function, which means that it does not follow the convention of other commands, and does not require the
underscore when used as an operand. The resolution is 14 bit, or 1.2mV per bit. To read analog inputs
from a slave controller, use the SA command.

When using this command to access I/O on a slave controller in distributed control mode, use it with the handle for
outbound master commands. Do not use the handle which is for incoming slave update packets. For example, if a
slave is connected on handles E and F, reference the I/O for the slave on handle E.
