Hardware Errors

Error messages in the editing mode of the signal graph:

Message: The hardware list changed. The measuring card is offered, could not be found however not at its old position in the selection box. Please you control the adjustments in the hardware Setup of the Modules.
Note: After an update of the driver Modules changed the order of the measuring cards in the selection box. The measuring card used is now at a different position. An automatic correction took place, the check of the adjustments in the dialogs was recommended.
Message: The desired measuring card is not offered. Please use another card.
Note: The signal graph was created using a different operating system. The operating system used at present does not offer a driver for the selected measuring card. Offer evade you on another card.
Message: False driver version!
Note: The used driver DLL of the hardware manufacturer is probably too old. One in the ICONNECT driver used API function cannot be found.
Message: Measuring card not found!
Note: The selected measuring card cannot be found at the selected identification number (DEVICE ID).
Message: The card needs a complete channel chain beginning with channel 0.
Note: The selected measuring card can head for analogue inputs only then, if beginning starting from channel 0 a channel list without gaps is structured, thus e.g. 0-1-2-3 but not 0-1-4-7.
Message: Adjusted frequency had to be modified.
Note: The sum scanning rate is too small or excessive. It is corrected for the admissible limit values.

Error messages while runtime:

Message: The sampling rate is too high. The measurement was interrupted.
Notes: to the measuring adjustments sampling rate/block size
Sample:
block size 1, sampling rate 1, time 1 s
block size 1, sampling rate 1000, time 0.001 s
block size 100, sampling rate 1, time 100 s
Optimization of information flow-rate and latency by the correct selection of the block size:
As flow-rate of a signal graph one defines the highest scanning rate, with which the signal graph runs still in real time, i.e. with that the driver buffer constantly does not fill. Latency one calls the delay between scanning a Samples and the reaction of the signal graph; this reaction can insist both in the output of a control value, as well as in the representation of the result on the monitor.
Message: Hardware parameters changed. The measurement must again be started.
Note: New values for sampling rate or block size are sent while runtime (external parameters). These become only effective after restart of the signal graph.
Message: It was not selected an I/O channel.
Note: No channels are configured.
Message: The digital port was already occupied with other direction.
Note: It is tried to access a digital port (port A, b, c) which was already programmed with another digital direction.
Message: It is tried to output a value outside of the valid parameter area.
Note: A hardware driver function is addressed with an invalid parameter.
Message: The output rate is too high. The measurement was interrupted.
Note: With the synchronous analog output cannot be served the card with the desired output rate.
