AOUT Instruction Block
The example below shows an AOUT block for an Analog Rail module connected
to port 2 of a local I/O head, which in turn is connected to port 3 of an AutoMate
Processor. Data from register 2000 is used in this example.
SRC Ć Register number from which the data to output will be taken.
IOPORT Ć Processor port to which the Analog Rail is connected (directly or
indirectly); value range 0Ć3.
LHPORT Ć Local I/O Head port to which the Analog Rail is connected; value
range 0Ć3. If a Local I/O Head is not used, the value is 0.
CHAN Ć Channel on the Analog Rail module to write; value range 0 or 1.

4.2 Analog Rail Module in DCS 5000/AutoMax
Systems
This section describes how the Analog Rail is used with
DCS 5000/AutoMax systems.
4.2.1 Configuring the Analog Rail Module with a
DCS 5000/AutoMax Remote I/O Head
The Analog Rail module is used in the Local Head mode when the
host is a DCS 5000/AutoMax Remote I/O Head. For AutoMax
Version 3.0 and later, the Analog Rail module is configured using the
AutoMax Programming Executive. Refer to instruction manual
JĆ3750 for more information. For DCS 5000 or AutoMax Version 2.1
or earlier, the module is defined in the configuration task for the
master rack using the DCS 5000 or AutoMax Programming
Executive software. See instruction manual JĆ3649 for more
information on the configuration task.
