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.
For example:
|
|
External Input/Output
|
Internal Relay
|
Timer
|
Data Register
|
|
Company M
