DO 0 to 15
signal
Parallel Judgement Output
The judgement results of judgement 0 to 15 set in the processing item [Parallel Judgement Output]
are output to DO 0 to 15.
Reference:
"Processing Item List Manual", "Parallel Judgement Output" (p.406)
Parallel Data Output
The measurement values set in data 0 to 7 in the processing item [Parallel Data Output] are output
in 16-bit format. Reference:
"Processing Item List Manual", "Parallel Data Output" (p.403)
●
Only integers are output.Decimals are rounded up.
●
The range of values that can be output is as follows:
When in binary format: -32768 to +32768
When BCD format: -999 to +999
When measurement values are outside of these ranges, the following apply.
For binary format:
When measurement value is < -32768: -32767 is output.
When measurement value is > +32768: +32768 is output.
For BCD format:
When measurement value is < -999: -999 is output.
When measurement value is > +999: +999 is output.
●
For the output format, select from a 2's complement binary format or BCD format.
For a definition of 2's complement, see Reference:
Terminology Explanations (p.271) .
●
Output Sequence
Measurement results are output in sequence starting with the smallest processing unit No.
Example) When [Parallel Judgement Output] is processing unit 5 and [Parallel Data Output] is
processing unit 8
Note
●
After measurement, the data output by the OR signal or DO signal is held until the next measurement is
performed.Note that the output state will be maintained even after measurement is complete.
However, when [One-shot OR signal] is on in Reference:
Setting Communication Specifications (Parallel
Interface) (p.178) , the OR signal will turn off after the set output time has elapsed.
●
The output signal factory default setting is OFF, but the signal may be ON for approx. 0.5 sec when power is
turned on.Be careful of signal loading occurring at external devices.
