    Section 6-6 Slave Station Input Data Slave Station Input Data The following diagram shows the structure of the input data for the Slave Sta- tion. The input contact data (variables) for I/O Slave Stations from unit number 1 to 64 are stored in addresses 0004H to 0043H of variable type 80. The Serial Master Station’s input/output data is cleared when the power is turned OFF.

Serial number registration status indicates whether the serial number is also registered when registering an I/O Slave Station. The serial number reg- istration status for I/O Slave Stations from unit number 1 to 64 are stored in addresses 0083H to 0086H of variable type 82.

    (2) Class 2 is not satisfied if the Power Supply Units are operated in parallel. WT30 Terminals require a 24-VDC power supply. Provide a power supply of at least 15 W, considering the inrush current generated at startup. An OMRON Switching Power Supply Unit is recommended.

  • Page 117: 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)
  • Page 118: Wireless Communications Delay (Twcy)

    Appendix C I/O Response Time Wireless Communications Delay (T The response time required until an input signal from the I/O Slave Station is reflected in the Serial Master Sta- tion’s memory is a total of approximately 10 ms per I/O Slave Station plus the input filter time, as follows: Response time = T ×...
