4. I/O Variable Definition
In order to input or output with CODESYS, input variable to I/O Mapping or Parameters, and define
variables of I/O channel.
In this example, assigning variable [DO00] in bit 0 of CPSN-DO-08BL DO port is defined as I/O
variables.
This example also applies to most of other I/O modules or I/O in the different controllers.
1
Add [CPSN-DO-08BL] as demonstrated in the previous page “Add I/O modules (page 61) “,
and double click the icon on the device window.
* I/O functions within the controller are pre-registered under the tree hierarchy (listed as in
PCB271 I/O) of CODESYS device window.
2
When the configuration window appears, select [Internal I/O Mapping].
3
(1) Open the tree that has “do0-7” strings in the [Channel] row.
