Appendix 6 Processing Time
Cyclic transmission delay time
The following are the formulas to calculate cyclic transmission delay time.
Between the master station and an intelligent device station/remote device station
■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
CT: Inter-module synchronization cycle
n1: SM CT (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)
■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
CT: Inter-module synchronization cycle
n2: CT 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)
