F - Real | Yes | Yes | Single | 4 bytes |
Address: Indicates the data address in the memory area.
Ex: %E0000 (Operand = E, Address = 0)
- %<Operand><TableId>[TablePosition]
Operand: Indicates the memory area, the valid values are:
Operand | Read | Write | Bit Read | Bit Write | Data Type | Address size |
|---|---|---|---|---|---|---|
TM - Memory Table | Yes | Yes | Yes | Word | 2 bytes | |
