Diagnostic
Our ICT-Tool offers extensive diagnostic functions that enable targeted detection of errors in control or wiring. Any DELIB errors that occur are automatically recorded and used for detailed analysis in the event of possible malfunctions.
Access times tests
This test can be used to determine the access times to the module. The test values are read and written in 8, 16, 32, or 64-bit commands.
Access times Register
The following example checks the register accesses to an Ethernet module. The average access time here is 0.5 ms.
Access times Analog I/O
In the following example, the access times to an Ethernet module with analog I/Os are checked. The average access time here is 0.6 ms.
Access times Digital I/O
In the following example, the access times to an Ethernet module with digital I/Os are checked. The average access time here is 0.6 ms.
Cable return test
The cable return test can be used to check the function of all digital and analog inputs and outputs (I/Os) of a module. To do this, inputs and outputs are wired together externally on a 1:1 basis. The test software analyzes whether the output signals arrive correctly at the inputs, thereby identifying wiring errors or hardware defects.
Analog test
In analog test mode, the D/A converter outputs defined test voltages, which are then read in by the A/D converter and compared with the target values. The software counts the number of test runs and automatically documents any deviations.
Digital test
In the digital test, the switching states of the relay or MOSFET outputs are fed back externally to the optocoupler inputs. Here, too, the software counts and compares the number of cycles and automatically detects transmission errors or deviations.
A/D quality measurements
The quality of an A/D measurement is influenced by various factors and can be affected by external interference. A reliable method for checking measurement quality is to measure a stable battery voltage. Our diagnostic tools can be used to determine the residual ripple and noise behavior.
A/D ripple
The A/D ripple test can be used to measure the residual ripple of the individual A/D inputs and check for interference signals such as mains hum or voltage instabilities.
A/D noise
The noise behavior of each A/D channel can be displayed graphically using A/D noise measurement. Additional filter stages with averaging can be used to smooth and improve the measurement signal.
FIFO In/Out
Hier können Sie den Software-FIFO Ihres NET-Moduls testen und sich Statuswerte ausgeben lassen.
D/A output test
The D/A output test enables targeted testing of each individual D/A channel of a module. A freely selectable test voltage can be output directly. Currently, simple square wave signals with configurable high and low times are available. The signals can be monitored simultaneously with an oscilloscope. This function is also ideal for long-term tests. The test software detects DELIB errors and logs them automatically.
