Program example of cyclic transmission
The following shows a program example of cyclic transmission.
■Overview of the program example
D0 of the control station (station No.1) is sent to Y50 to Y5F of the normal station (station No.2) through cyclic transmission.
In the program example, an interlock is established with link relay (LB) and cyclic data is sent.
Each number in the figure, from No.1 to No.2, represents a station number.
No.1 is control station and No.2 is normal station.
