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. |
