Once all of the hardware for a rack has been configured, you can configure the

variables in each rack. Configuring variables consists of attaching symbolic

names

to the variables that must be accessible to more than one application task

in the rack. There are two categories of variables that are configured: I/O

locations that are connected to field signals and the common memory variables

on Processor modules and Common Memory modules. Local variables, i.e.,

those

that do

not need to be accessed by more than one application task, are not

configured. They are defined in the application task in which they are used.

Three different forms" are used to configure variables: a basic form used for I/O

and interface modules (including UDC modules), a form used for common

memory modules, and a form for Network Interface modules (M/N 57C404). The

correct form, including any preĆdefined dedicated registers, is automatically

called up when you select a module to configure.

10. To configure variables on a selected module, select Configure Variables from

the pull down menu. You can also zoom in to configure the variables by

double clicking on the selected module. For Processor and Common

Memory modules, the form displays item numbers to be configured, not

be configured will be displayed on the screen, in pages and views where

applicable.

Views are logical collections of

registers, e.g., interrupt registers. A

Page

is a contiguous set of 64

registers within a view

. If multiple views exist, a

dialog box will prompt you for the view you want to configure.

The Programming Executive software incorporates three features that allow you

to configure variables more quickly: copy/paste, autoĆname, and substitute. All

three of these options are found on the Configure Variables pullĆdown menu.

After

configuring the variables in

the rack, you can create application tasks for the

rack. Before you can create a new task, you must first add the task to the rack.

11. Select the Manage Tasks command from the Rack menu. Select the Add

command from the Task menu. Select New on the resulting dialog box for a

new task. Enter the task name, along with the other information prompted for

in the next dialog box. This procedure adds the name of the application task

and

all information about it to the selected rack. The application task can now

be created/edited.

12. Select the Edit Task command from the Task menu (or doubleĆclick the

selected task). The Programming Executive will call up the appropriate editor

(PC editor for PC tasks or text editor for all other types). See the appropriate

language instruction manuals for more information. See this instruction

manual for information on the PC editor.

13. When you are finished editing the task, save it and select Compile from the

Manage Tasks menu. .PC and .INC tasks do not need to be compiled.

Compilation

statistics (or errors) will be printed to the screen and to log files if

the log option is selected.
