4.8 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 Station ψslave transmission delay time
xt: Slave ψMaster Station Transmission Delay Time
Master Station
ψ For the master station -> slave transmission delay (Yt) and slave o master station
transmission delay (xt), refer to the Operation Manuals for the CompoNet master unit and
PLC installed in the master unit.
