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
- 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.
| | Input format (DI7 to DI0) | |
---|
| | Command information (DI4 to 0) |
---|
| Measure continuously during input of commands. | | | ***** The controller does not see this signal, so a setting of either 0 or 1 makes no difference. | |
| Switch measurement scenes. | | | Input "Scene No." in binary format. | Switch to scene 2. Input Example: 10100010 |
| Switch measurement scene groups. | | | 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. | 1 | 10 | 00000 | Input Example: 11000000 |
Clear Error | Clear error output. The ERROR indicator is also cleared. | 1 | 10 | 00001 | Input Example: 11000001 |
Clear Parallel OR+DO | Clear the OR signal and DO signal. | 1 | 10 | 00010 | Input Example: 11000010 |
Note - When the input command is not received correctly, the ERROR signal turns on.
Important
- During parallel continuous measurement and when the STEP signal is input continuously, do not perform switching of the scene group. When this is performed, set "Unchecked" in "Save scene group on scene switch" in either of the settings items below.
Output Format
Each time measurement is performed, the measurement result is output.
| |

| Overall judgement results are output. |
| Parallel Judgement 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.
- 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 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.
