LogicPro User’s Guide Chapter 6: Variables

Doc.# 28002-00 Rev 3.00 Watlow Anafaze 59

a) Place a check mark in either the Input or the Out-

put check box.

b) Select the I/O driver from the list. The drivers in the

list are determined by the Resource you selected.

Information on these drivers is located in Chapter

12, “I/O Drivers.”

c) Enter the I/O physical address. See Chapter 12,

“I/O Drivers,” for addressing information.

d) Select one of the following I/O sizes from the list of

sizes:

• Bit — a binary digit that can hold the value of

0 or 1.

• Word — 16 bits in length.

10. Enter any comments in the Comment field.

11. Click [OK].

NOTE! If the I/O point is an Input, you must choose Input.

If the point is an output, choose Output if you in-

tend for the logic Program to set the output’s

state. You may also choose Input for a physical

output if its state is set by the closed-loop control

Program and the logic Program is only interested

in sensing the value or state of the physical out-

put. For database registers, choose Input or Out-

put based on whether the logic Program sets the

value (output) or just reads it (input).

The Variable appears in the dialog box list. The next time you

add a Variable, the Add Variable dialog box remembers the

previously entered type and size fields. This makes it easier

and faster to add many similar Variables to a Resource/

Program.

Editing a Resource/Program Variable

Resource and Program Variables are edited in the same

manner. To edit a Resource/Program Variable:

1. Select the Variable you want to edit in the Resource/

Program Variables dialog box.

2. Click [Edit]. The Edit Variable dialog box appears.

3. Enter the appropriate information in all the dialog box

fields, according to the procedure in “Adding a Re-

source/Program Variable” on page 56.
