I/O Format (Parallel Interface)

Input Format

When the Main screen is viewed, the following commands are input:

STEP signal
Perform a measurement when STEP signal is ON.
DSA signal
This is a signal to inform that the external device is ready to receive data and that the measurement by the controller has also completed.

DI signal

The commands are input in the following formats. DI signals can be set to "0" (OFF) or "1" (ON).
Confirm commands and information, and turn DI7 (Perform) ON with an interval over 1ms.

Table: Input Commands
Item	Description	Input format (DI7 to DI0)			Example for Input
Item	Description	Perform (DI7)	Command (DI6 to DI5)	Command Information (DI4 to 0)	Example for Input
Continuous measurement	Measure continuously during input of commands.	1	00	***** Controller doesn't view this signal, independently from setting of either 0 or 1.	Example for Input: 10000000
Scene switch	Switch measurement scenes.	1	01	Input "Scene No." in binary format.	Switches to scene 2. Example for Input: 10100010
Scenegroup switch	Switch measurement scene group.	1	11	Input "Scene Group No." in binary format.	Switches to scene group 2. Example for Input: 11100010

0: OFF 1: ON

Note

ERROR signal is ON if input command isn't received correctly.

Important

When parallel continuous measuring is engaged and continuous STEP signal is inputted, switching of scene group should be avoided. To switch a scene group, uncheck "Save scene group when switching" by either of the following methods.
- The Switch Scene Group window Switching the Scene Group
- [Measure setting] in the [Measure] menu Setting for Measurement

Output Format

Output the measurement results whenever performing measurement. The result is output only if "Output" of [Test Measurement setting] in the "Control" area is checked.

Setting for Measurement
When judgemnet results are either OK or NG, it's possible to choose output ON. Ex-factory setting is "ON if NG".

Setting Communication Specifications (Parallel Interface)

Table: Output Format (Parallel Interface)
Signal	Output Contents
OR Signal	Output comprehensive Judge
DO 0 to 15 signal	Parallel Judgement Output The results of Judge 0 to 15 set in [Parallel Judgement Output] are output to DO 0 to 15. Processing Items List Manual, "Parallel Judgement Output"
DO 0 to 15 signal	Parallel Data Out Value of Data 0 to 7 in [Parallel Data Out] are output in 16-digits format. Processing Items List Manual, "Parallel Data Out" Only integral part of a value can be output. Value shall be circled up. The range of output value is as follows: Binary format: -32768 to +32768 BCD format: -999 to +999 The measurement value beyond the range is as follows: Binary: -32768 measurement value: Output -32767. Measurement value >+32768: output +32767. BCD: -999 measurement value: Output -999. Measurement value >+999: output +999. For output format, 2's complement or BCD format are available. For 2's complement, see Terminology. Output Sequence Measurement results are sequentially output from smaller processing unit No. Example) When [Parallel Judgement Output] in processing unit 5 and [Parallel Data Out] in processing unit 8 are set

Note

After measurement, the data output to OR signal or DO signal shall be kept until next measurement. Please note, output state shall be maintained even if measurement is finished.
When the Output "One-shot OR signal" Setting Communication Specifications (Parallel Interface) is set to ON, however, the OR signal, after the set output time has lapsed, will turn to OFF.
Ex-factory output is set OFF, and about 0.5s ON is maintained if switching-on. Due attention shall be paid to signal reading of external devices.
