Maximum I/O response time (T MAX)
TM-out-min
The maximum I/O response time is the total of the following terms:
TPLC
T MAX = IN + T S + T M-in-max + T PLC × 2 + T M-out-max + T S + OUT
T MAX : Maximum I/O response time
T PLC : PLC’s cycle time
IN: Input delay in the Slave (Refer to 2-5-3 Slave I/O Delay Times on
page 51.)
OUT: Output delay in the Slave (Refer to 2-5-3 Slave I/O Delay Times on
page 51.)
T S: Communications cycle time
