Specialities:
Inputs I Depends on PCD.
Max = 8191
Outputs O Depends on PCD.
Max = 8191
Registers R 4095
Share the same addresses
Flags F 8191 You can set a range of
volatile flags if you like
to.
Constants K 16383(32Bit) or
8191 (13Bit(##)
Timers T 0 to X
Counters C X to 1599
Texts X 0 to Y
DataBlocs DB Y to 3999
RAM Texts RAM X 3990 to Z
RAM Data RAM DB Z to 4999
Blocs
Share the same addresses.
First timers
then Counters
Share the same addresses.
First texts then
DB’s
Share the same Address
range.
PCD 2 goes up to 5999
PCD 4/6 go up to 7999
Every element ( input / output / register / timer/ ect) in your project can have a
name, these names are called SYMBOLS. There are:
• Symbols from a Network editor
These symbols are known to all the PCD’s in the Workspace. They are created
in one of the network editors like “S-Net”.
• GLOBAL Symbols
These Symbols can be used in every file of the current project. Each project
has it’s own project-shared symbols.
• LOCAL Symbols
These symbols can only be used inside the active program file. Each program
file has it’s own local symbols.
You can search for symbols. You can drag and drop symbols from one editor to
the other. And you can import/export symbols.
