AO
FUNCTION: Analog Out
DESCRIPTION:
The AO command sets the analog output voltage of Modbus Devices connected via Ethernet.
ARGUMENTS: AO m, n where
m is the I/O number calculated using the following equations:
m = (SlaveAddress*10000) + (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 255. Please note that the use of slave devices
for modbus are very rare and this number will usually be 0.
HandleNum is the handle specifier from A to F.
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 9.99 to –9.99
