Remark
A station with a Basic model QCPU or safety CPU will receive another station's data in LB/LW0 to 3FFF, which is set in
"LB/LW Setting(2)", however, they will not be refreshed to the CPU module's devices.
Only the direct access to link devices is available. ( Page 70, Section 4.1.4)
(b) When a station other than Universal model QCPUs exists on the network
The station cannot receive other stations' data of station No.65 and higher.
(c) When a Universal model QCPU exists on the network
If the group cyclic transmission function is used, the station can receive other stations' data of the same shared
group and those of the stations to which no shared group is set.
It does not receive data of other stations in different shared groups. ( Page 83, Section 4.1.8)
