Appendix 5.3
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
Block Data Assurance per Station
Calculation
value
Asynchronous mode
Normal value
(SM × 1) + (LS × n1) + Rio
Maximum
(SM × 1) + {LS × (n1 + 1)} + Rio
value
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
(
(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
Block data assurance per station
Calculation
value
Asynchronous mode
Normal value
(SM × n2) + (LS × 1) + Rio
Maximum
(SM × n2) + (LS × 2) + Rio
value
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
