3.8 I/O Signal Timing
When any of the control signal is turned ON to perform the operation of the robot cylinder using the PLC's
sequence program, the response (status) is returned to the PLC. The maximum response time is expressed
using the following formula.
Max. Response Time (msec) = Yt + Xt + 2 + Command Processing Time (Operation Time, etc.)
Yt: Master Station to Remote I/O Station Transmission Delay Time
Filed Network Transmission Delay Time
Xt: Remote I/O Station to Master Station Transmission Delay Time
For the Master Station to Remote I/O Station Transmission Delay Time (Yt) and the Remote I/O Station to
Master Station Transmission Delay Time (Xt), refer to the instruction manuals for the CC-Link Master Unit and
mounted PLC.
