Diagnostic interrupt
With the help of bit 6 of byte 0, you may release the diagnostic interrupt. In
case of an error, the record set 0 with a size of 4byte is transferred to the
superordinated system.
More detailed information is to find below under "Diagnostic data".
Function-no.
Here you set the function-no. of your measuring function for every channel.
Please see the according table above.
Option-Byte
Here you may set the transducer velocity for every input channel. Please
regard that a higher transducer velocity causes a lower resolution because
of the lower integration time.
The data transfer format remains unchanged. Only the lower Bits (LSBs)
are not longer relevant for the analog value.

*) These specifications apply to 1channel operation. For multi-channel operations, the conversion rate
per channel can be calculated by dividing the specified conversion rate by the number of active
channels.
