The feedback test for digital and analog I/Os makes it possible
Simulation of long-term tests and reliable fault diagnosis
With the newly integrated signal feedback test, the ICT tool from DEDITEC GmbH offers a user-friendly solution for comprehensive testing of all digital and analog inputs and outputs (I/Os) of a module.
This allows long-term tests to be carried out without any programming effort – whether during initial commissioning or after years of use.
The signal feedback test also makes it possible to detect errors in the connection wiring or rule out hardware defects.
How it works
In the signal feedback test, the inputs and outputs are connected to each other 1:1 via an external cable. Within the test software in the ICT tool, the outputs and inputs can be linked in blocks or individually.
The tests can also be performed with different delay times. During the run, the software detects whether the outgoing signals are correctly read back at the corresponding inputs. It reliably analyzes and detects transmission errors or deviating switching states.
