(b) Devices for which network refreshing can be executed
64 transfer settings (LX, LY, LB, LW), one SB transfer setting and one SW
transfer setting can be performed for each network module.
It is possible to transfer to different devices.
SB, LB, B, LX, LY, X, Y, M, L, T, C and ST can be set in 16-point units, and
SW, LW, W, D, R and ZR can be set in one-point units.
