The inputs and outputs are automatically addressed (preset in the device on delivery). At least 1
byte of inputs or outputs is reserved for each module. The rotary switch of the CPX-CEC-…-V3,
for example, only occupies 4 bits of inputs, but 1 byte is reserved.
Alternatively you can also address the inputs and outputs manually.
3. Save the project and close the dialog by clicking "Close".
Addressing settings
The I/O addresses are automatically assigned by Codesys.
The I/O addresses are edited directly in the I/O mapping for the respective module.
When adding a module to an existing project at a later time:
•
Specify the address manually.
This will prevent subsequent module addresses from shifting.
Note
With manual address assignment, Codesys does not perform a check for possible overlaps in the
I/O range.
•
Check the distribution of the address ranges.
