30.3.2 Using Addresses with Flexible Names (Variable Format)

The following explains the symbol variables that you can use when [Register Variable] is set to [Variable Format].

Use symbol variables that are not fixed to the hardware to create a reusable logic program.

In GP-Pro EX, you can name variables and use them in logic programming. For most PLCs, data storage areas are handled as device addresses in registers named by the PLC manufacturer.

Example:

 

External Input/Output

Internal Relay

Timer

Data Register

Company M

X001

M100

T200

D00001

Company O

01

1001

TIM000

DM0000
