The total number of symbols you can register is 10000.
The total variables you can register differs depending on the model. (You cannot register variables with the GP-4100 Series (Monochrome Model).)
GP-3200 Series, ST3000 Series: 1000
Other models: 6000
You can check the registration status of variables by selecting the [Project Information] in the [Information] from the [Project] menu and open the [Logic] tab in the [Memory Usage], from the displayed dialog box and then click [Details] from the [Variable Capacity].
The device number (including array settings) of each variable that can be registered is as follows.
Bit Variable: 8000
Bit Variable Inputs: 512
Bit Variable Outputs: 512
Integer Variable: 8000
Integer Variable Inputs: 128
Integer Variable Outputs: 128
Float Variable: 128
Real Variable: 128
Timer Variable: 512
Counter Variable: 512
Date Variable: 64
Time Variable: 64
PID Variable: 64
You cannot use symbols set up as an array in logic programs.
When using symbol variables with a bit address type, symbol variables with any element number other than 0 will result in an error on GP-Viewer EX.
