Appendix 5.3 Cyclic transmission delay time
The following is the formula to calculate cyclic transmission delay time.
(1) Between the master station and an intelligent device station/remote device
station
(a) Master station (RX/RWr)  Intelligent device station/remote device station (input)
The following time is shown:
• The time between a signal input to the intelligent device station/remote device station and the CPU module
device of the master station turning on or off
• The time between data input to the intelligent device station/remote device station and the data being
stored in the CPU module device of the master station
SM : Master station sequence scan time
LS : Link scan time
n1 : SM  LS (Round up the calculated value to the nearest integer.)
Rio : Intelligent device station/remote device station processing time
( Manual for the intelligent device station/remote device station used)
(b) Master station (RY/RWw)  Intelligent device station/remote device station (output)
The following time is shown:
• The time between the CPU module device of the master station turning on or off and the output of the
intelligent device station/remote device station being turning on or off
• The time between data set to the CPU module device of the master station and the data output to the
intelligent device station/remote device station
SM : Master station sequence scan time
LS : Link scan time
n2 : LS  SM (Round up the calculated value to the nearest integer.)
Rio : Intelligent device station/remote device station processing time
( Manual for the intelligent device station/remote device station used)
