Master station  local station
When data is transmitted from a local station to the master station as follows:
• Master station (RX)  local station (RY)
• Master station (RWr)  local station (RWw)
• Master station (LB)  local station (LB)

Station-based block data assurance
(SM  n2) + (LS  1) + Rio
(SM  n2) + (LS  2) + Rio
Description
Master station sequence scan time
Communication cycle intervals (can be checked in the SW0060)
Processing time of the remote station
Round up the calculated value to the nearest integer of (LS  SM)
Station-based block data assurance
If LS < SL: (SM  1) + (LS  (n1 + 1)) + (SL  1)
If LS  SL: (SM  1) + (LS  (n1 + 2))
(SM  2) + (LS  (n1 + 2)) + (SL  1)
Description
Master station sequence scan time
Communication cycle intervals (can be checked in the SW0060)
Local station sequence scan time
Round up the calculated value to the nearest integer of (SM  LS)
Station-based block data assurance
If LS < SM: (SM  1) + (LS  (n3 + 1)) + (SL  1)
If LS  SM: (LS  (n3 + 2)) + (SL  1)
(SM  1) + (LS  (n3 + 2)) + (SL  2)
Description
Master station sequence scan time
Communication cycle intervals (can be checked in the SW0060)
Local station sequence scan time
Round up the calculated value to the nearest integer of (SL  LS)
No station-based block data assurance
