4.7 Possible uses of onboard drive and measuring system interface in the application (C230-2, C240)
The table below lists the combination possibilities for the C230-2/C240.

Note
A standard output and a drive cannot be used simultaneously on one axis channel.
The input (X3 to X6) used as a counter input cannot be used simultaneously as an encoder input.
When a project is created and when a project is downloaded, a consistency check of the
permitted combinations per axis channel is automatically performed.
This results in the following possibilities in the application for the C240, for example:
• Configuration of hydraulic axes on the onboard resources of the C240
• Use of unassigned axis channels of the C240 as I/O variable for the user program
• Use of the analog outputs of the C240 as unassigned process outputs
Note: The resolution and the characteristic curve of the analog output of the C240 differ from
those of a SIMATIC S7 controller. The following table lists the digital values and their
associated analog values (characteristic curve).
