 About Double Speed Multi-input
Two cores performs the same inspection flow alternatively, which help to shorten measurement takt
time.
Example: Normal processing with a single core CPU
Example: Processing using the Double Speed Multi-input 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 sta-
tus 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 series and FZ5-800/1100/1200 series Sensor Controller both have a multi-core CPU. Using the
Double Speed Multi-input, where each CPU core takes turns in the execution of the measurement pro-
cessing, realizes the reduction of the minimum takt time
*1
by up to 1/2 for the FZ5 series Sensor Con-
troller and 1/4 for the FH-3050.
*1. The fastest takt time is the shortest time that is allowed to accept a STEP signal without causing a backlog of
images.
Refer to Double Speed Multi-input on page 4-15.
