AO (Analog Out)
[I/O]
DESCRIPTION:
The AO command sets the analog output voltage of the local analog output or ModBus devices connected
via Ethernet.
ARGUMENTS: AO m, n where
m is either the local analog output voltage ranging from 9.9982 to -9.9982 or the I/O number calculated
using the following equations:
m = (SlaveAddress*1000) + (HandleNum*1000) + (Module-1)*4) + (Bitnum-1)
Slave Address is used when the ModBus device has slave devices connected to it and specified as
Addresses 0 to 225. Please note that the uses for ModBus are very rare and this number will usually be 0.
HandleNum is the handle specifier from A to P (1 - 16).
Module is the position of the module in the rack from 1 to 16.
BitNum is the I/O point in the module from 1 to 4.
n = the voltage which ranges from 9.9982 to –9.9982. If m is < 1000, n is omitted.
USAGE:
OPERAND USAGE: _AO returns the value of the local analog output in volts.
