* 1 The own station send range for LB/LW of a Basic model QCPU or safety CPU must be set within
the range of LB/LW0 to 3FFF in [LB/LW settings (1)].
If it is set to LB/LW4000 or higher, or set in [LB/LW settings (2)], a LINK PARA. ERROR or a
NETWORK PARAMETER ERROR will occur when parameters are received.
POINT
The LB/LW points for each station can be set to 16384 (3FFF
H
) or less. (Total of
[LB/LW settings (1)] and [LB/LW settings (2)])
(1) Assuring 32-bit data integrity
If settings are made with the following conditions 1) to 4) satisfied, 32-bit data integrity
will be automatically assured. (
Section 4.1.5 Assurance of cyclic data integrity)
1) The start device No. of LB is a multiple of 20
H
.
2) The points assigned per station in LB is a multiple of 20
H
.
3) The start device No. of LW is a multiple of 2.
4) The points assigned per station in LW is a multiple of 2.
