Configuration of digital inputs/outputs (X142)
You configure the required digital input/outputs and operating modes over interface X142.
Overview of supported operating modes
You can configure the following operating modes for the individual channels of the X142 interface:
列表: Overview of operating modes
Operating mode of X142 I/Os | Functionality | Use with technology objects (TOs) | Use via I/O area (without TO) | Isochronous mode |
|---|---|---|---|---|
DI | Digital input Input delay (1 µs/125 µs) Hardware interrupt (optional) Hardware interrupt at rising and/or falling edge | Hardware limit switch for positioning and synchronous axes | No OB restrictions | Optional |
DQ | Digital output | Output cam Cam track | No OB restrictions | Optional |
Timer DI | Acquisition of the switching time of a digital input ** with up to two edges per application cycle (e.g. for use as measurement sensing input) | Measuring input (OB 91 required) | OB 91/OB 6x | Required |
Timer DQ | Precisely timed output of a digital output ** with up to two edges per application cycle (e.g. for use as an output cam output) | Output cam (OB 91 required) Cam track (OB 91 required) | OB 91/OB 6x | Required |
Oversampling DI | Acquisition of 32 states of a digital input ** at equal intervals per application cycle | --- | OB 91/OB 6x | Required |
Oversampling DQ | Output of 32 states of a digital output ** at equal intervals per application cycle | --- | OB 91/OB 6x | Required |
Event/period duration measurement | Measurement of number of edges and period duration (e.g. for simple speed measurement with hole mask and light barrier) | --- | OB 91/OB 6x | Required |
Pulse width modulation PWM | Output of a configurable pulse-pause ratio with a configurable frequency | --- | No OB restrictions | Optional |
Procedure
Select the Device configuration entry in the project tree under the CPU. The device view opens.
In the device view, click the DI/DQ 8x24VDC [X142] interface. You can now edit the configurable properties under Properties in the Inspector window.
You can find an overview of all channels and your selected settings under Channel parameters.
