4.7 I/O Signal Timings
When any of the control signal is turned ON to perform the operation of the actuator 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)
ዙYt+xt+3+ command processing time (operation time, etc.)
Yt: Master Stationĺslave transmission delay time
xt: SlaveĺMaster Station Transmission Delay Time
Master Stationĺ For the master station
o slave transmission delay (Yt) and slave o master station
transmission delay (xt), refer to the Operation Manuals for the EtherCAT(R) master unit
and PLC installed in the master unit.
