3.7 I/O Signal Timings
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.
Maximum response time (msec)䋽Yt+Xt+3+ command processing time (operation time, etc.)
Yt: Master stationoslave transmission delay time
Xt: Slaveomaster station transmission delay time
Master Station o For the master station o slave transmission delay (Yt) and slave omaster station
transmission delay (Xt), refer to the operation manuals for the EtherNet/IP master unit
and PLC installed in the master unit.
