Values that have been saved are transferred to the backplane asynchronously to the CPU without influencing cyclic data transfer so that they can be analyzed in the application. The memory size (12 KB) allows recording of extensive current or voltage processes.
It doesn't matter if only one channel or multiple channels are sampled. The sample rates can be configured from 100 Hz to 20 kHz. before the time when the trigger occurs and record the values until the memory is depleted. Start recording with a delay after the time when the trigger occurs.In particular, recording before the time when the trigger occurs is possible by continually saving the measurement values in parallel during normal operation and not just when the trigger conditions are met. Additionally, various sampling methods can be configured using definable trigger conditions or a direct start from the CPU: Sample a defined numbers of measurement values when a trigger occurs. Sample a defined number of measurement values when a trigger occurs in addition to a defined number of values that are available before the trigger occurs. Start recording in the past, i.e. That means the minimum and maximum values are continually resaved independently of the bus or CPU clock. Because the module has an extremely fast 50 µs conversion time, it includes an internal electronic slave pointer for minimum and maximum values. In this way, nearly all application requirements can be fulfilled with only one module. As above, we start the data acquisition, wait for the oscilloscope to be ready and transfer the data: The raw plott looks pretty confusing, because we the different rounds are just. Center the falling edge at 20 of these 200ms.

The software filters are also configured. Trigger on the falling edge at 138 mV (on channel 7). Like all X20 analog modules, the measurement function of each individual channel can be configured for current (0.20 mA) or voltage (± 10 V). The 2-channel and 4-channel 16-bit X20 analog input modules not only have a high conversion resolution, they also have other special characteristics. JA new function is now available for the proven X20 I/O system from B&R. Analog I/O modules with oscilloscope function
