You cannot use symbols set up as an array in logic programs.
On the GP-Pro EX, you can use (Device Address) of the connection device/PLC and the addresses of the display unit's data storage area.
These addresses can be used in two ways, as follows.
For a device address (Device Address), use the original addresses of device/PLC or display unit, for example, [PLC1]X00100 or [#INTERNAL]LS0100.
For a symbol variable, you can assign a name to the device/PLC or the address of display unit, such as "sales_quantity" or "stock_quantity".
There are two kinds of Symbol Variables.
Names applied to device addresses are called symbols.
You can manage all addresses using names, and even use these names when defining the address in parts and other objects.
Allocatable device address:
Bit address and Word address
You cannot use symbols set up as an array in logic programs.
Items that are assigned to the variable area of the display unit are called "variables."
There are two ways to register variables as follows.
Variable format:
Allows you to name each variable.
When creating a new project file, select [Variable Format].
If you selected a model that does not support logic functions, you cannot select [Address Format].
You can select [Address Format] only when creating a new program. You cannot change the format to [Address Format] after you create a program.
29.3.2 Using Addresses with Flexible Names (Variable Format)
Address Format:
Uses External Addresses Use this format when there are too many addresses to name.
You can change the method from [Address Format] to [Variable Format] even during logic programming. However you cannot change back from [Variable Format] to [Address Format].
Even if the number of addresses in the logic program exceeds the number of variables, you can change the format from [Address Format] to [Variable Format]. This causes only the addresses in the logic program to change to variables.
Thus, not all the addresses available to the logic program are changed into variables.29.3.3 Using Prepared Addresses (Address Format)
PLC Address (Device Address)
External Address
Connection Device Address
This looks up the connection device data.
You can use this area only when communication with the device/PLC is set through a direct access system.
For example, [PLC1]X00100
You cannot use disabled addresses to read devices/PLC. For unreadable addresses, refer to the "GP-Pro EX Device Connection Manual".
Internal Address
These are temporary storage locations for saving data such as the values operated on or controlled in the display unit.
LS Area
This contains free user areas and an area for operating the display unit.
You can use this area only when communication with the device/PLC is set through a direct access system.
For example, [#INTERNAL]LS0100
USR Area
You may use all areas as you like, up to 30,000 Words.
For example, [#INTERNAL]USR00100
Memory Link System Area
This area acts as a medium for the host write/read request.
You can use this area only when communication with the connection device is set through a memory link.
For example, [#MEMLINK]0100
These variables have predefined functions. They display and control the state of the display unit when a logic program is run. The system variables cannot be deleted.
