Point Address Syntax
The syntax for the ControlLogix communication points is: <File Type><File Number> : <Address>
- File Type: identifies the Operand.
- File Number: number reference for the File Type
- Address: address number in the PLC.
The valid values for File Type are:

Address | Description |
F8:1 | File Type = F, File Number = 8, Address = 1 |
F8:2 | File Type = F, File Number = 8, Address = 2 |
N7:1 | File Type = N, File Number = 7, Address = 1 |
B3:10 | File Type = B, File Number = 3, Address = 10 |
ST11:1 | File Type = ST, File Number = 11, Address = 1 |
DLG0:34 | ile Type = DLG, Queue Number = 0, Number of Bytes = 34 |
Consider the table below to calculate the Number of Bytes for the DataLogging
