Appendix 10 Low-Speed Cyclic Transmission Function
The low-speed cyclic transmission function is convenient when sending data that does
not require a high-speed transfer to other stations in a batch mode using the cyclic
devices (LB/LW).
Although it is a cyclic transmission, the performance is the same as that of the transient
transmission.
A station can transmit data only once in a single link scan. To send data from multiple
stations simultaneously, the link scan time should be longer than the total transmission
time for all the sending stations.
In the low-speed cyclic transmission, the send range for each station is set with the
common parameters of the control station. The following screen shows the network
range assignment settings of the common parameters.
Low-speed cyclic send range
for each station
The sending to other stations can be activated by three methods: 1) Transmit data of
one station in 1 scan (default), 2) Fixed term cycle interval setting, and 3) System times.
These methods can be designated by the supplementary settings of the common
parameters, and only one of them can be selected.
The screen shown below is the supplemental screen where the activation method can
be selected.
