Precautions for Correct Use
• Click the upper left of the Image Display Pane and set the Image mode to Freeze Image.
For details, refer to 3-2-7 Changing the Image Mode and Other Display Contents on page
3 - 21.
• If images are taken consecutively at high speed, the number of images that you will be able
to take will be limited. If the maximum number of images have been taken, the READY signal
will not turn ON until the current processing is completed. Therefore, the next STEP signal
cannot be input.
• The ERROR terminal turns ON if a STEP signal is input when the READY signal is OFF.
• If the trigger signal input rate is faster than the communications output, some STEP signals
may be skipped and measurements may be delayed. Make sure to input trigger signals at a
rate that does not cause a delay in communications.
• The multi-input function cannot be used in the following cases:
- The flow has more than one camera input processing unit.
- The flow has a Camera Image Input HDR or Camera Image Input HDR Lite processing unit.
- Branching is used to process a single camera input processing unit more than one time.
- Measurement triggers are input through means other than parallel or EtherCAT communica-
tions(non-procedure commands or measurement commands through a PLC Link).
- The built-in lighting of an Intelligent Compact Digital Camera, FZ-SQ££££, is used.
• If a measurement trigger is input while using the multi-input function, the last NG image can-
not be displayed.
• If images and data are logged to a network drive, the use of the multi-input function and other
heavy measurement loads on the Controller may slow down communications and cause log-
ging errors. In this case, set the measurement takt time so that there is some leeway.
• When the multi-input function is in use, most of the resources of the CPU are allocated to
measurement processing. This may cause performance drops (delayed responses and pack-
et losses) and communications errors. Do not use Ethernet/IP communications while the mul-
ti-input function is in use.
