Remote I/O Communications Characteristics Section 7-1
CVM1- and CV-series PLCs (Synchronous Mode)
Minimum I/O Response
Time The minimum I/O response time occurs with the I/O timing shown in the fol-
lowing diagram.
T
IN
: The Input Slave’s ON (OFF) delay (Minimum value: 0)
T
OUT
: The Output Slave’s ON (OFF) delay (Minimum value: 0)
T
RT-IN
: The Input Slave’s communications time/slave
T
RT-OUT
: The Output Slave’s communications time/slave
T
PLC0
: The PLC’s cycle time (instruction exe peripheral servicing)
Note Refer to the information on each slave in SECTION 5 to SECTION 7 for
details on Input and Output Slaves’ ON and OFF delay times. Refer to 7-1-2
CompoWay/F Communications Cycle Time and Refresh Time and the Opera-
tion Manual for the PLC being used for details on the PLC’s cycle time.
