(2) Master station and local stations
(a) Master station (RX)
Local station (RY)
Shows the time after the local station CPU module device is turned on or off until the master station CPU
module device is turned on or off.
[m = 1]
[m = 2 to 4]
SM : Master station sequence scan time
LS : Link scan time
SL : Local station sequence scan time
n : (LS × m)
LS (Round up the calculated value to the nearest integer.)
n1 : SM
LS (Round up the calculated value to the nearest integer.)
k : SL
(LS × m) (Round up the calculated value to the nearest integer.)
m : Number of points of "RWw/RWr Setting" set for the local station in "Network Configuration Settings"
(b) Master station (RY)
Local station (RX)
Shows the time after the master station CPU module device is turned on or off until the local station CPU
module device is turned on or off.
SM : Master station sequence scan time
LS : Link scan time
SL : Local station sequence scan time
n3 : SL
