  • Page 118: I/O Response Time

    Appendix C I/O Response Time I/O Response Time Compared with a wired network, wireless communications may be delayed due to the influence of the sur- rounding electromagnetic environment, making it difficult to achieve the calculated response time. The calcula- tion method is provided here as a guide. The response time required until an input signal from the I/O Slave Station reaches the personal computer or PLC via the Serial Master Station can be estimated as follows: T1: I/O Slave Station input filter (10 ms/100 ms)
