Vision System FH/FZ5 Series
User’s Manual (Z340)
Example: Normal processing with a single core CPU
Example: Processing using the Single-line High-speed Mode with dual-core CPU
Multi-input Function
With the multi-input function, images are input consecutively and at high speed. This allows the next STEP to be
received as soon as the image input processing is completed. There is no need to wait for measurement
processing to be completed. You can check whether image input processing has been completed with the status
of the READY signal.
There are no setting items for the multi-input function. You can use it as long as you can check the status of the
READY signal, i.e., as long as you use parallel or EtherCAT communications. With EtherCAT communications,
check the status of the Trigger Ready signal instead of the READY signal.
The FH and FZ5-11
both have a multi-core CPU. Using the Single-line High-speed Mode, where each CPU
core takes turns in the execution of the measurement processing, realizes the reduction of the minimum takt
time (*1) by up to 1/2 for the FZ5 and 1/4 for the FH.
*1: The fastest takt time is the shortest time that is allowed to accept a STEP signal without causing a backlog of images.
Reference: Single-line High-speed Mode (p.269)
