l 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 sig-
nal.
The FH/FHV series Sensor Controller have a multi-core CPU. Using the Double Speed Multi-
input, 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 1/4 for the FH-3050 Sensor Controller.
*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 - 13.
