I/O Response Time Characteristics Section 2-5
TMIN = IN + TS(IN) + TM-in-min + TI/O + TPLC + TM-out-min + TS(OUT) + OUT
TMIN : Minimum I/O response time
TPLC : PLC’s cycle time
Ts (IN): Input data transmission time for one node
High-speed Communications Mode: 20 µs
Long-distance Communications Mode: 160 µs
TM-in-min :Input processing time in the Master
Master Input processing time
CS Series, C200HX/C200HG/
C200HE-(Z)E, and C200HS
160 µs
CS Series 20 µs (allocated words for 1 unit
number), 25 µs (allocated words for
2 unit numbers)
CJ Series 25 µs
CQM1 120 µs
T M-out-min: Minimum output processing time in the Master
Master Min. input processing time
CS Series, C200HX/C200HG/
C200HE-(Z)E, and C200HS
35 µs
CS Series 35 µs (allocated words for 1 unit
number), 45 µs (allocated words for
2 unit numbers)
CJ Series 45 µs
CQM1 40 µs
TS (OUT) : Output data transmission time for one node
High-speed Communications Mode: 15 µs
Long-distance Communications Mode: 110 µs
IN: Input delay in the Slave (Minimum value is 0.)
OUT: Output delay in the Slave (Minimum value is 0.)
TI/O : I/O refreshing time
