(4) Precautions
(a) When a station other than Universal model QCPUs exists on the network
The station cannot receive other stations' data of station No.65 or higher.
(b) When a station with 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. (
