Program example

Program example of transient transmission
The following shows a program example of transient transmission.
■Overview of the program example
Through transient transmission, by using the READ instruction, the values in D300 to D304 of the normal station (station
No.2) are read to D800 to D804 of the control station (station No.1).
When creating a program, configure an interlock using 'Baton pass error status of own station' (SB0047) and 'Baton pass
status of each station' (SW0070 to SW0073).
