Programming Languages Ladder Logic (LD),
Sequential Function Charts (SFC),
Structured Text (ST), and
Instruction Lists (IL)
Function Blocks Maximum number of definitions 2,048
Maximum number of instances 2,048
Tasks Type of Tasks Cyclic tasks
Interrupt tasks (Power OFF interrupt tasks, scheduled interrupt tasks, I/O interrupt tasks, and
external interrupt tasks)
Number of Tasks Cyclic tasks: 128
Interrupt tasks: 256
(Interrupt tasks can be defined as cyclic tasks to create extra cyclic tasks. Therefore, the total
number of cyclic tasks is actually 384 max.)
Symbols
(Variables)
Type of Symbols • Local symbols: Can be used only within a single task in the PAC.
• Global symbols: Can be used in all tasks in the PAC.
• Network symbols (tags): I/O memory in the CPU Unit can be externally accessed using symbols, depending on
parameter settings.
Data Type of Symbols • BOOL (bit)
• UINT (one-word unsigned binary)
• UDINT (two-word unsigned binary)
