Master station  local station
When data is sent 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)
• Master station (LW)  local station (LW)
Calculation value Station-based block data assurance
If LS < SL: (SM  1) + (LS  (n1 + 1)) + (SL  1)
Normal value
If LS  SL: (SM  1) + (LS  (n1 + 2))
