Transmission Delay Time
CAUTION
Due to difference in communication protocols, the transmission delay time of the S-LINK V system
differs from that of the conventional S-LINK system.
For transmission, there are fastest transmission time and the slowest transmission time.
Since this product uses the serial transmission method, transmission will be carried out as shown in the follow-
ing figure.
For a detailed description of the following controllers, refer to their respective user's manuals.
