2.2 Introduction to Configuring Racks and
Variables
Once you create the system/section/rack structure for your
application, you can begin to configure the hardware in your
installation. Hardware configuration consists of adding modules to
each rack (including network and remote racks, UDC modules, and
PMI rail hardware) to reflect the actual installation. AutoMax Executive
V3.x checks that modules are added properly. For example, a
second AutoMax Processor module can be added only after a
Common Memory Module (M/N 57C413 or 57C423) has been
added. If your application includes modules that are not supported in
V3.x, you can use generic" modules. There are three generic
modules: one with 32,768 registers (GEN32K), one with 8000H
registers in hex (GEN32KH), and one with 32 registers (GEN32) for
use in a remote I/O rack (or in a main rack when 32 registers are
sufficient). Note that GEN32K and GEN32KH modules can be used
only in a rack that contains an AutoMax Processor module.
After you have added a module, you can map variables to I/O points
or common memory on that module using forms" tailored as
required for the specific register organization on each module. This
variable configuration map," along with information about the
application tasks for the rack, is stored in databases, and must be
compiled and downloaded to the rack along with application tasks
before application tasks can run in the rack. This configuration
information is sometimes called the configuration task.
After you have completed the physical configuration of your system,
you can generate a bill of material which lists all of the racks, heads,
rails, and modules used in the system along with the needed
batteries, cables, and optional hardware and software. See Appendix
L for additional information.
2.3 Introduction to Creating Application Tasks
After you have configured I/O points and common memory using
variable names, you can create application tasks using these variable
names instead of locations. You can create BASIC tasks, PC/Ladder
Logic tasks, and Control Block tasks. BASIC and Control Block tasks
are stored in text files which are edited using a text editor; PC/Ladder
Logic tasks are stored in binary files and edited using a custom
editor. A text editor (Norton Editor) and the PC Editor are both
included with the AutoMax Programming Executive software. In
addition, you can create include" files which are added to a BASIC
or Block task when it is compiled (by using the BASIC language
INCLUDE statement).
Once the variables have been configured and the application tasks
created, you can compile the tasks to create object code that will run
on the AutoMax Processor or UDC module(s) in the rack. PC/Ladder
Logic tasks are stored as object code and do not need to be
compiled.
