I/O Format (Parallel Interface)

Input Format

When the Main screen is displayed, the following commands can be input.
  • STEP signal
    Measurement is performed once when STEP signal turns on.
  • DSA signal
    When "Output control" is set to "Handshaking", this is a signal to provide notification that the external device is ready to receive data.
    Setting Communication Specifications (Parallel Interface)
  • DI signal
    Commands can be input in the following format.Set 0 (OFF) or 1 (ON) for each DI signal.
    Confirm commands and information, and turn DI7 (run) ON with an interval of at least 1 ms.

*****
The controller does not see this signal, so a setting of either 0 or 1 makes no difference.
Input Example: 10000000
Scene switch
Switch measurement scenes.
1
01
Input "Scene No." in binary format.
Switch to scene 2.
Input Example: 10100010
Scene group switch
Switch measurement scene groups.
1
11
Input "Scene Group No." in binary format.
Switch to scene group 2.
Input Example: 11100010
Clearing Measurement Values
Clear measurement values.
The OR signal and DO signal are not cleared.

Clear Error
Clear error output.
The ERROR indicator is also cleared.

Note
  • When the input command is not received correctly, the ERROR signal turns on.

Output Format

Each time measurement is performed, the measurement result is output.
Output can be selected to turn on either when the judgement result is OK or when it is an NG error.The factory default setting is "ON at NG".
Setting Communication Specifications (Parallel Interface)
Signal
Output contents
OR Signal
Overall judgement results are output.
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.
"Processing Item List Manual", "Parallel Judgement Output"
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."Processing Item List Manual", "Parallel Data Output"
  • 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 Terminology Explanations.
  • 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
Timing chart sample
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 Setting Communication Specifications (Parallel Interface), 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.
