Conduct Test Runs on 3D Measurement System
In this phase, you need to conduct test runs on the 3D measurement system to make sure that an external device can obtain measurement results normally.
Prerequisites for Test Runs
Before testing the 3D measurement system, the following conditions must be satisfied:
-
If the laser profiler uses an external device to trigger each round of data acquisition, make sure that the external device can normally input signals to the laser profiler to trigger one round of data acquisition.
-
If the laser profiler uses an encoder to trigger line scans, make sure that the encoder can input the signals that trigger line scans to the laser profiler normally.
-
TCP ASCII communication has been enabled for the external device and a TCP connection has been established with the 3D measurement system.
In addition, before testing the 3D measurement system, you need to prepare sample objects (including OK and NG ones) and the values (reference values) measured by other measurement instruments.
| For more information about TCP ASCII communication, refer to TCP ASCII Communication Workflow and TCP ASCII Commands. |
Procedure of Test Runs
The procedure for conducting test runs on the 3D measurement system is as follows:
-
After the object is in place, an external device (such as a photoelectric sensor) sends a signal to trigger data acquisition.
-
The laser profiler acquires data.
-
An external device (such as a PLC) sends a command to trigger the Mech-MSR project to run. For example:
trigger, 1
This command triggers the Mech-MSR project with ID 1 to run. Project ID is the number before the project name in the project list.
-
An external device obtains the measurement result output by the Mech-MSR project.
return, 1
This command obtains the measurement result output by the Mech-MSR project with ID 1. The format of the result returned by this command is set by the Data format of return commands parameter in the Communication Configuration window.
-
Confirm that the external device can receive the measurement result normally and parse it.
-
Confirm that the measurement result and measured values of each sample are consistent with the reference values.
If the measurement result and measured values output by the 3D measurement system are consistent with the reference values, the 3D measurement system can be used in the production line.
